Enhanced wear resistance of blades made of martensitic steels: …
The measured wear rates of martensitic stainless steels and powder steel S35VN were well described by a composite model of wear, and the wear resistance was mainly enhanced by more volume fraction of M 23 C 6 carbides. At the same time, two strategies that substantially improve the wear resistance of blade steels were proposed.Web
