Abstract
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 high-chromium cast iron takes place. The processes kinetics is studied, kinetic parameters are found, activation energy and diffusion coefficient of carbon are calculated
