Grinding–hardening using dry air and liquid nitrogen
Grinding–hardening using dry air and liquid nitrogen

This is because, as revealed experimentally , the penetration ofliquid nitrogeninto thegrinding zoneis extremely limited such that the high heat dissipation due to the boiling ofliquid nitrogenis effective only outside thegrindingzone. Thecoolingconditions were accounted in the model as represented by Eqs.
