Grinding hardening can obtain effect besides fine machining on the surface of workpiece. A certain degree micro-damage will be formed during grinding process which mainly contains micro-crack, melting coating, decarburization, and scratch. In order to study hardening, paper carries a experiment characteristics are observed. The generation mechanism micro-crack is revealed. It by accumulation di...

We proposed a novel numerical method for the reliable prediction of decarburization with CO2. In our method, mass, momentum, and energy conservation equations are solved simultaneously, where reactive mass transfer, compressibility, moving interface between gas liquid fully considered. reaction model, we assumed that rate-limiting processes transfer in phase interfacial rate. Our quantitatively...
