Abstract
This paper proposes an innovative development of a grinding-hardening technology using an inert cryogen-liquid nitrogen. This technology not only integrates precision surface grinding with surface hardening treatment, but at the same time, produces satisfactory surface integrity of ground components, including compressive surface residual stresses and fine microstructure with a high hardness and wear resistance. The technology is cost-effective and because of the inert nature of the cryogen, the grinding process becomes environmentally conscious.
