Abstract:
A method for selective carburization of an article using low pressure induction carburization includes: providing or procuring an article including a surface; subjecting the article to directed induction heating, wherein a first portion of the surface of the article is inductively heated to a temperature that exceeds a carburizing temperature, while a second portion of the surface of the article remains at a temperature below the carburizing temperature; and simultaneously with subjecting the article to directed induction heating, subjecting the article to low pressure carburization, thereby selectively carburizing the first portion of the surface of the article while not carburizing the second portion of the surface of the article.
