Effect of heat treatment on wear properties of plain carbon steel

摘要

A study was made of the effect of heat treatment upon the wear resistance of low and high carbon steels as determined by the ball on a plate wear-testing machine (diamond indenter) under combined action of rolling and sliding friction under pressures. Total ten samples of the steel (5 samples each from low carbon and high carbon range) were subjected to five different heat treatments i.e. annealing, normalizing, oil quenching, water delay quenching and water quenching heated to a temperature of 960¢ªC. One from each heat treated types was prepared for microstructural and hardness studies. The hardness of the five different heat treated samples was measured by Vickers hardness testing machine. Optical microscopies to study the microstructure and Scanning electron microscopic analysis of wear surface have been done.
