Abstract
In this research, study the effect of coating of tungsten carbide on tribological performance of H13 tool steel was investigated by wear tests, and we made analysis for tungsten carbide coating on wear performance of H13 steel with visually technique by using Scanning Electron Microscope (SEM) and 2D-3D topography images, friction coefficient experiment, and volume loss parameters. As per the results which obtained from wear tests, the tungsten carbide coated steel decreased the friction coefficient by 23% compared to the uncoated steel, and a mechanism of wear was more superficial. The aim of this study is to increase the wear resistance and hardness of H13 hot work tool steel by using tungsten carbide coating.
