Wear assessment of plasma nitrided AISI H11 steel
Research highlights ► Thickness of diffusion and compound layers depends on nitriding conditions. ► Wear behavior of nitrided samples depends on surface hardness. ► Formation of oxide layer decreases the friction coefficient and wear weight loss.
Abstract Plasma nitriding is one of the effective methods for improvement of the hardness, wear and corrosion resistance of steels. In this research AISI H11 hot working tool steel was plasma nitrided in various gas mixtures for different times and temperatures. The morphology, size and composition of nitride nanoparticles formed on the surface of the specimens were investigated using scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray diffraction (XRD). The wear behavior of plasma nitrided samples was studied by means of unlubricated pin-on-disc method under constant load of 80N, sliding speed of 1m/s, sliding distance of 2000m at room temperature. The results showed plasma nitriding process improved the wear behavior of H11 steel. The increase in time and temperature of plasma nitriding decreased the hardness and increased the wear weigh loss of the specimens.
