Hardening wear proof coatings developed by heat treat? Needless to say. But, with so many processes available, where can you start? How can you choose?
Start with a knowledge of one's metal chemistry. For instance, dimensionally stable steels, people that have higher carbon and increased chromium content, are recognized for their great resistance to wear. Due to chromium, various other favorable carbide forming components as well, like tungsten, manganese or molybdenum, can produce higher hardness.

But, besides alloy composition, consider material stress reduction, tempering or austenitizing temperatures. If you want the very best distribution of carbide, hardness high quality of the metal matrix, that is.
Just how do we define hardness, anyway? Generally speaking, hardness is really a measurement of a surface's capability to withstand indentation, deformation, when another item is applied with stress against it. Ideals reflect particular loads, over given areas, by counter-experience indentation, of known materials properties.

Heat therapy options are differ and wide. And they are very specific. So, can say for certain the differences among these thin movies. Otherwise, negative outcomes range from, based on metal and high temperature treat procedure, inter-granular (oxidation) cracking, breakdown in grain boundary, precipitant development, retained austenite, along with other issues.
"Ion nitriding" metal, for instance, involves diffusion of nitrogen in to the metal. Based on responses between ionized nitrogen with alloying elements electrically, harder areas, though superficial, are produced. Another choice in high temperature treating will be "carburizing." There, higher temperatures are essential to diffuse carbon in to the metal surface area, to a particular depth, for the production of martensite.

Before you select your heat treat, understand these procedures, their effects on metallurgy, and what surface properties best fit your preferences. Only after that, will your hardening wear resistant coatings last best!
