Wear rates were generally increasing with test temperature, especially FeCrC as it more than doubled from RT (0.0015 mm 3 /impact) to 0.0034 mm 3 /impact at 700 °C. The hardfacing FeCrNbBWC showed a 4-fold increase in wear rates at 700 °C compared to RT, nevertheless it was still observed to be the best material for this condition.

Discover how wear simulation can help improving the durability of mining equipment, reducing downtime and operational costs. The Basics of Wear. Wear refers to the gradual loss or deformation of material on a surface due to mechanical action, such as friction, sliding, or rolling contact between surfaces.
The mean impact lives to breakage ranged from 21,000 to over 300,000 for steel balls and from 18,000 to over 300,000 for alloyed white cast iron balls. For the harder steel types that did not break and for all alloyed white cast irons, the major impact wear mode was spalling, with rates of 0.28 to 4.5 mg per impact.
This thesis examines the effects of wear and friction on energy consumption in the mining industry. It is divided into two parts: 1) an overview of the global mining industry, energy usage, and impacts of wear and friction, and 2) case studies of highly energy intensive mining equipment. The document provides background on the scale and operational stages of the global mining …
