A\u00e7o ferramenta produzido por metalurgia do p\u00f3 versus a\u00e7o ferramenta produzido por fus\u00e3o convencional<\/h1>\n\n\n\n

Dois a\u00e7o para ferramentas<\/a> Barras podem ter a mesma denomina\u00e7\u00e3o de grau e ainda assim comportar-se de maneira completamente diferente na linha de produ\u00e7\u00e3o. A composi\u00e7\u00e3o qu\u00edmica da liga \u00e9 frequentemente semelhante, \u00e0s vezes id\u00eantica, mas uma barra prov\u00e9m de um lingote est\u00e1tico e a outra de p\u00f3 atomizado consolidado sob press\u00e3o. Essa \u00fanica diferen\u00e7a na forma como o metal l\u00edquido se solidifica \u00e9 a causa principal de quase todas as discrep\u00e2ncias de propriedades que os compradores encontram ao comparar a\u00e7os metal\u00fargicos e convencionais.<\/p>\n\n\n\n

Este artigo analisa a origem dessa lacuna, o que ela altera na ferramenta final e quando o custo adicional do gerenciamento de projetos realmente vale a pena.<\/p>\n\n\n\n

Como os dois processos solidificam o a\u00e7o<\/h2>\n\n\n\n

O a\u00e7o ferramenta convencional come\u00e7a em um forno el\u00e9trico a arco e \u00e9 fundido em lingotes est\u00e1ticos ou blocos de fundi\u00e7\u00e3o cont\u00ednua. Para a\u00e7os onde a limpeza \u00e9 crucial, as usinas adicionam uma etapa secund\u00e1ria de refus\u00e3o, refus\u00e3o por eletroesc\u00f3ria ou refus\u00e3o por arco a v\u00e1cuo, para reduzir a porosidade na linha central, gases aprisionados e macroinclus\u00f5es. O que a fundi\u00e7\u00e3o convencional n\u00e3o pode evitar \u00e9 o tempo. Um lingote grande esfria ao longo de horas, \u00e0s vezes dias, e durante esse per\u00edodo os elementos de liga t\u00eam espa\u00e7o para migrar. O resultado \u00e9 a segrega\u00e7\u00e3o micro e macrosc\u00f3pica, o bandamento qu\u00edmico que aparece posteriormente como veios de carbonetos na microestrutura.<\/p>\n\n\n\n

O a\u00e7o produzido por metalurgia do p\u00f3 come\u00e7a da mesma forma, com fus\u00e3o por indu\u00e7\u00e3o, mas o fluxo de material fundido nunca entra em contato com um molde. Jatos de g\u00e1s de alta press\u00e3o o atomizam em got\u00edculas finas que se solidificam quase instantaneamente ao ca\u00edrem atrav\u00e9s de uma torre de atomiza\u00e7\u00e3o. Essa taxa de resfriamento \u00e9 v\u00e1rias ordens de magnitude mais r\u00e1pida do que a fundi\u00e7\u00e3o de lingotes e \u00e9 r\u00e1pida o suficiente para suprimir a rea\u00e7\u00e3o eut\u00e9tica grosseira de carbonetos que causa a segrega\u00e7\u00e3o. O p\u00f3 resultante \u00e9 peneirado, selado em recipientes e consolidado at\u00e9 atingir a densidade total por prensagem isost\u00e1tica a quente, sendo ent\u00e3o forjado ou laminado em barras da mesma forma que o a\u00e7o convencional.<\/p>\n\n\n\n

Tamanho e distribui\u00e7\u00e3o de carbonetos<\/h2>\n\n\n\n

A taxa de solidifica\u00e7\u00e3o \u00e9 o fator crucial aqui. O resfriamento lento d\u00e1 aos carbonetos tempo para crescerem e se aglomerarem na dire\u00e7\u00e3o do fluxo do lingote, e ent\u00e3o a lamina\u00e7\u00e3o estica esses aglomerados, transformando-os em faixas. A solidifica\u00e7\u00e3o r\u00e1pida nunca lhes d\u00e1 essa chance.<\/p>\n\n\n\n

Essa diferen\u00e7a de ordem de grandeza no tamanho dos carbonetos \u00e9 o que se reflete posteriormente em termos de tenacidade, retificabilidade, usinabilidade e estabilidade dimensional.<\/p>\n\n\n\n

Tenacidade e propriedades transversais<\/h2>\n\n\n\n

Os carbonetos em faixas oferecem um caminho f\u00e1cil de seguir, e esse caminho \u00e9 pior na dire\u00e7\u00e3o transversal, perpendicular \u00e0 dire\u00e7\u00e3o de lamina\u00e7\u00e3o. O a\u00e7o ferramenta convencional \u00e9 visivelmente mais fraco nessa orienta\u00e7\u00e3o, o que \u00e9 importante para qualquer ferramenta submetida a cargas em m\u00faltiplos \u00e2ngulos, em vez de diretamente ao longo do eixo da barra. Como o a\u00e7o PM n\u00e3o possui faixas de carbonetos, suas propriedades permanecem consistentes independentemente da dire\u00e7\u00e3o da medi\u00e7\u00e3o. Para ferramentas sujeitas a impactos ou cortes interrompidos, essa isotropia costuma ser o fator decisivo em rela\u00e7\u00e3o aos valores brutos de dureza.<\/p>\n\n\n\n

Capacidade de moagem e usinabilidade<\/h2>\n\n\n\n

A capacidade de retifica\u00e7\u00e3o \u00e9 geralmente medida pela rela\u00e7\u00e3o G, o volume de metal removido por unidade de desgaste da rebolo. Carbonetos grandes e duros, particularmente os carbonetos MC ricos em van\u00e1dio, n\u00e3o retificam de forma limpa. Eles fraturam ou arrastam-se pela rebolo, desgastando-a rapidamente, por isso as ligas convencionais de alta resist\u00eancia apresentam baixas rela\u00e7\u00f5es G. Os carbonetos PM s\u00e3o suficientemente pequenos para se desprenderem durante a retifica\u00e7\u00e3o sem danificar o abrasivo, e o a\u00e7o PM pode retificar at\u00e9 dez vezes mais r\u00e1pido do que uma liga convencional com teor de carboneto compar\u00e1vel.<\/p>\n\n\n\n

A mesma distribui\u00e7\u00e3o fina e uniforme de carbonetos facilita a usinabilidade no estado recozido. O processamento por metalurgia do p\u00f3 tamb\u00e9m permite que as usinas aumentem o teor de enxofre para obter a\u00e7os de usinagem livre sem a perda de trabalhabilidade a quente que a metalurgia convencional sofre, uma vez que os sulfetos de mangan\u00eas permanecem pequenos e dispersos, em vez de formarem filamentos.<\/p>\n\n\n\n

Estabilidade dimensional por meio de tratamento t\u00e9rmico<\/h2>\n\n\n\n

Todo a\u00e7o ferramenta sofre deforma\u00e7\u00e3o durante o processo de t\u00eampera, mas a forma como essa deforma\u00e7\u00e3o ocorre \u00e9 crucial. A segrega\u00e7\u00e3o e a estrutura direcional de carbonetos fazem com que o a\u00e7o convencional se deforme de maneira irregular, frequentemente adquirindo um padr\u00e3o quadrangular reconhec\u00edvel \u00e0 medida que perde a circularidade. O a\u00e7o metal\u00fargico (PM) se deforma uniformemente em todas as dire\u00e7\u00f5es, de modo que a ovaliza\u00e7\u00e3o se mant\u00e9m pr\u00f3xima a um c\u00edrculo perfeito. Essa deforma\u00e7\u00e3o previs\u00edvel \u00e9 mais f\u00e1cil de compensar na fase de projeto e reduz o risco de trincas por t\u00eampera em geometrias complexas.<\/p>\n\n\n\n

A resist\u00eancia ao desgaste \u00e9 mais complexa do que parece.<\/h2>\n\n\n\n

Este \u00e9 o erro mais comum entre os compradores de produtos. Para uma composi\u00e7\u00e3o qu\u00edmica id\u00eantica, o a\u00e7o convencional pode, na verdade, apresentar uma resist\u00eancia ligeiramente melhor ao desgaste abrasivo puro, porque seus carbonetos maiores atuam como blocos que impedem o deslizamento das part\u00edculas abrasivas. No entanto, a maioria das falhas reais em ferramentas decorre do desgaste adesivo e da microfissura\u00e7\u00e3o, e n\u00e3o da abras\u00e3o pura, e \u00e9 a\u00ed que o a\u00e7o metal\u00fargico se destaca, j\u00e1 que seu campo uniforme de carbonetos resiste muito melhor \u00e0 microfissura\u00e7\u00e3o e ao lascamento.<\/p>\n\n\n\n

A maior vantagem \u00e9 a liberdade de liga. O processamento PM possibilita a produ\u00e7\u00e3o de ligas como CPM 10V, CPM Rex 76 e ASP 60 com n\u00edveis de van\u00e1dio, ni\u00f3bio e cobalto que se fragmentariam durante a conforma\u00e7\u00e3o a quente se fundidas convencionalmente. Essas ligas PM superligadas atingem resist\u00eancia ao desgaste e dureza a quente incompar\u00e1veis a qualquer liga convencional, simplesmente porque nenhum lingote convencional conseguiria manter essa composi\u00e7\u00e3o qu\u00edmica durante a forjagem.<\/p>\n\n\n\n

Resposta ao tratamento t\u00e9rmico<\/h2>\n\n\n\n

Os carbonetos finos se dissolvem mais rapidamente durante a austenitiza\u00e7\u00e3o, portanto o a\u00e7o PM atinge a dureza m\u00e1xima a uma temperatura de t\u00eampera mais baixa e responde de forma mais uniforme em toda a pe\u00e7a. Dito isso, o a\u00e7o PM n\u00e3o tolera um ciclo de tratamento t\u00e9rmico inadequado, assim como o a\u00e7o convencional. Uma ferramenta PM com tratamento t\u00e9rmico inadequado ainda ter\u00e1 desempenho inferior a uma ferramenta convencional tratada termicamente corretamente.<\/p>\n\n\n\n

Quando vale a pena pagar o pr\u00eamio do seguro de manuten\u00e7\u00e3o preventiva.<\/h2>\n\n\n\n

O a\u00e7o ferramenta metal\u00fargico normalmente custa de 5 a 50% ou mais do que o equivalente convencional, e os a\u00e7os convencionais ainda cobrem cerca de 90% do mercado porque as ferramentas padr\u00e3o n\u00e3o precisam do que o metal\u00fargico oferece. O metal\u00fargico justifica seu pre\u00e7o em algumas situa\u00e7\u00f5es espec\u00edficas.<\/p>\n\n\n\n

Geometrias complexas de ferramentas, como fresas, machos e alargadores, onde a distor\u00e7\u00e3o irregular durante a t\u00eampera comprometeria as toler\u00e2ncias de acabamento, se beneficiam do movimento previs\u00edvel do metalurgia do p\u00f3. Ferramentas sujeitas a impactos fortes ou cortes interrompidos se beneficiam da tenacidade isotr\u00f3pica do metalurgia do p\u00f3, que resiste ao lascamento que danificaria uma ferramenta convencional. Aplica\u00e7\u00f5es que exigem extrema resist\u00eancia ao desgaste abrasivo ou adesivo justificam a ado\u00e7\u00e3o de ligas de metalurgia do p\u00f3 superligadas, sem equivalente convencional. Grandes blocos de ferramentas, incluindo matrizes de fundi\u00e7\u00e3o de grande porte<\/a>, se beneficiam da aus\u00eancia de segrega\u00e7\u00e3o proporcionada pela PM, uma vez que a segrega\u00e7\u00e3o em um grande bloco convencional acelera a fadiga t\u00e9rmica e o trincamento por calor ao longo da vida \u00fatil do chip.<\/p>\n\n\n\n

Fora esses casos, um \u00f3leo mineral convencional de boa proced\u00eancia e com certificado de teste de f\u00e1brica sem ressalvas cumpre a fun\u00e7\u00e3o por uma fra\u00e7\u00e3o do custo.<\/p>","protected":false},"excerpt":{"rendered":"
