Boride layer growth kinetics on X90CrMoV-18 steel
Sažetak
Boronizing is a type of thermal diffusion process with primary goal of increasing the surface hardness, wear, and corrosion resistance. Wear resistance of boronized parts depends on the type of borides that form on steel surface and their thickness. This paper focuses on evaluation of borides layers that form on martensitic stainless steel X90CrMoV-18. Pack boronizing was carried out at temperature range of 850-1000°C in duration of 1, 3 and 5 hours. After boronizing differences in surface boride layers were observed for different temperatures and time of boriding. Boriding compound depth and cross section hardness was measured. Results indicate difference in boride layer thickness and volume share of boride phases depending on temperature and time of boriding.
