Talk:Case hardening

From Wikipedia, the free encyclopedia

What is sorbitizing

My first guess is that it's treatment with sorbic acid, which looks like it would infuse carbon into the surface of the object being treated. I'll do some more digging and see what I can find. scot 15:07, 28 November 2006 (UTC)

Re recent edit - should case hardening link to Surface engineering so directly, as the first link in the list? Is it really a "surface process" in the same sense as the category uses it? It's really a bulk process that just has very limited access to the bulk of the material. Is this a pure "surface" treatment in the way that ion implantation etc. are?
