Principles of development of grinding media with increased wear resistance. Part 2. Optimization of steel composition to suit conditions of operation of grinding media

Abstract

The compositions of wear-resistant steels used as the material for grinding media are validated in order to obtain the optimal relation between the wear resistance and cost. Mathematical experiment planning reveals that low-alloyed hypereutectiod steels with the austenite-martensite structure without secondary carbides and eutectoid steels with the tempered martensite structure are the most promising for impact-abrasivecorrosive wear conditions.
