Decreasing the Impact–Abrasive Wear of Steel

详细

A new method of assessing the impact–abrasive resistance of steel permits simulation of the impact–abrasive wear with variation in the magnitude and inclination of the impact force, type of abrasive, and its grain size and rate of consumption. The influence of five carbide-forming elements on the properties of the cast and quenched steel is studied: specifically, attention focuses on the abrasion resistance, impact–abrasive resistance, and hardness of the steel. Optimal steel compositions with abrasion resistance and impact–abrasive resistance greater than that of 35GL steel are identified.
