When considering vacuum carburizing, audit post heat-treat processing cost to determine if the costs...

I have nothing against vacuum carburizing, I’ve spent a good deal of my career developing and selling the process, it’s just that few applications...

Interest in high-pressure gas quenching (HPGQ) increases

Hydrogen for high-pressure gas quenching (HPGQ) has the highest thermal conductivity and heat capacity of any commercially available gas, but currently is not used...

Carburizing vs. nitriding: Where does the future lie?

In last month’s column I highlighted difficulties in applying the plasma nitriding process. In many ways the process’s expected outcome had the right idea;...

The inside story of ionitriding in the United States

When ionitriding—or generically speaking, plasma nitriding technology—was being transferred to the United States from Germany in the mid eighties I was managing an R&D...

In applying heat-treat theory, understanding the reality of surface hardening equipment and processes is...

Much has been opined over the decades and presented in numerous formulae and graphs to explain the case hardening process, especially endothermic and low...
