Vantagens e desvantagens de adicionar tit\u00e2nio em a\u00e7o inoxid\u00e1vel austen\u00edtico<\/h2>\n

Quando o a\u00e7o inoxid\u00e1vel austen\u00edtico de cromo-n\u00edquel \u00e9 aquecido a uma faixa de temperatura de 450-800 \u00b0C, corros\u00e3o intergranular<\/a> mas a adi\u00e7\u00e3o de tit\u00e2nio melhorar\u00e1 essa situa\u00e7\u00e3o, mas isso \u00e9 bom ou ruim?<\/em><\/p>\n

A corros\u00e3o intergranular \u00e9, na verdade, causada pela precipita\u00e7\u00e3o de carbono da estrutura metal\u00fargica austen\u00edtica saturada na forma de Cr23C6, que faz com que a estrutura de austenita no contorno do gr\u00e3o se esgote em cromo. Portanto, evitar a defici\u00eancia de cromo no contorno do gr\u00e3o \u00e9 uma forma eficaz de prevenir a corros\u00e3o intergranular.<\/p>\n

Os elementos do a\u00e7o inoxid\u00e1vel s\u00e3o ordenados de acordo com o grau de afinidade com o carbono, na ordem de tit\u00e2nio e t\u00e2ntalo, molibd\u00eanio<\/a>cromo e mangan\u00eas. Pode-se observar que a afinidade do tit\u00e2nio e do carbono \u00e9 maior do que a do cromo. Quando o tit\u00e2nio \u00e9 adicionado ao a\u00e7o, o carbono se combina preferencialmente com o tit\u00e2nio para formar carboneto de tit\u00e2nio, o que pode efetivamente impedir a forma\u00e7\u00e3o de carboneto de cromo e a precipita\u00e7\u00e3o para formar um limite de gr\u00e3o pobre em cromo. Pode prevenir eficazmente a corros\u00e3o intergranular.<\/p>\n

Como o tit\u00e2nio e o nitrog\u00eanio podem se combinar para formar o nitreto de tit\u00e2nio, o tit\u00e2nio e o oxig\u00eanio podem ser combinados para formar o di\u00f3xido de tit\u00e2nio, portanto, a quantidade de tit\u00e2nio adicionada \u00e9 limitada. Para evitar a corros\u00e3o intergranular na produ\u00e7\u00e3o real de a\u00e7o inoxid\u00e1vel, a quantidade de tit\u00e2nio adicionado \u00e9 principalmente de cerca de 0,8%.<\/p>\n

Para evitar corros\u00e3o intergranular, o a\u00e7o inoxid\u00e1vel contendo tit\u00e2nio deve ser estabilizado ap\u00f3s o tratamento com solu\u00e7\u00e3o. Ap\u00f3s o tratamento em solu\u00e7\u00e3o, o a\u00e7o inoxid\u00e1vel austen\u00edtico obt\u00e9m uma estrutura de austenita monof\u00e1sica, mas o estado dessa estrutura n\u00e3o \u00e9 est\u00e1vel. Quando a temperatura \u00e9 elevada para mais de 450 \u00b0 C, o carbono na solu\u00e7\u00e3o s\u00f3lida precipita gradualmente na forma de carboneto, do qual Cr23C6. A temperatura de forma\u00e7\u00e3o \u00e9 650 \u00b0 C e 900 \u00b0 C \u00e9 a temperatura de forma\u00e7\u00e3o TiC. Para evitar a corros\u00e3o intergranular, \u00e9 necess\u00e1rio reduzir o teor de Cr23C6 e permitir que o carboneto exista completamente na forma de TiC.<\/p>\n

\"TiC\"<\/a><\/p>\n

Como a estabilidade do carboneto do tit\u00e2nio \u00e9 maior do que a do cromo, quando o a\u00e7o inoxid\u00e1vel \u00e9 aquecido acima de 700 \u00b0 C, o carboneto de cromo come\u00e7a a se transformar no carboneto de tit\u00e2nio. A estabiliza\u00e7\u00e3o consiste em aquecer o a\u00e7o inoxid\u00e1vel a 850-930 \u00b0 C durante 1 hora. Neste momento, o carboneto de cromo se decompor\u00e1 completamente para formar carboneto de tit\u00e2nio cinza ou preto est\u00e1vel, e a resist\u00eancia do a\u00e7o inoxid\u00e1vel \u00e0 corros\u00e3o intergranular \u00e9 otimizada. Al\u00e9m disso, o tit\u00e2nio \u00e9 adicionado ao a\u00e7o inoxid\u00e1vel para precipitar compostos intermet\u00e1licos Fe2Ti sob certas condi\u00e7\u00f5es para melhorar a resist\u00eancia do a\u00e7o inoxid\u00e1vel a altas temperaturas.<\/p>\n

Desvantagens:<\/strong>
\nO tit\u00e2nio tamb\u00e9m n\u00e3o \u00e9 totalmente inofensivo no a\u00e7o inoxid\u00e1vel e, \u00e0s vezes, o tit\u00e2nio tamb\u00e9m pode prejudicar o desempenho do a\u00e7o inoxid\u00e1vel. Por exemplo, existem inclus\u00f5es facilmente, como TiO2 e TiN, e seu conte\u00fado \u00e9 alto e distribu\u00eddo de maneira desigual, o que reduz a pureza do a\u00e7o inoxid\u00e1vel em certa medida; tamb\u00e9m piora a qualidade da superf\u00edcie dos lingotes de a\u00e7o inoxid\u00e1vel, resultando em um aumento na quantidade de moagem do processo, o que \u00e9 f\u00e1cil. Isso causa desperd\u00edcio; o desempenho de polimento do produto acabado n\u00e3o \u00e9 muito bom e o processamento de superf\u00edcies de alta precis\u00e3o \u00e9 muito dif\u00edcil.<\/p>\n
