It is found that during oxidizing heating at 1000-1150 оС the secondary and eutectic carbides dissolution accompanied by carbon content decreasing and chromium content increasing in surface layers of highchromium cast iron takes place. The processes kinetics is studied, kinetic parameters are found, activation energy and diffusion coefficient of carbon are calculated
