Different ratios CrC particle-reinforced Cu matrix composite materials and investigation of wear performance
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 7
Abstract
In this paper, Cu matrix composites (Cu-MCs) were fabricated using powder metallurgy (PM) technique and using different proportions of CrC particles in Cu matrix. CrC particles were added into pure Cu powder at different ratios as 5%, 10%, 15% and 20% by weight. The prepared composites were formed with 400 MPa pressure. The formed parts were sintered 60 minutes at 950°C. Sintered samples were evaluated by observating the density and scanning electron microscopy (SEM) images. Mechanical properties and microstructure of the produced composite materials (CMs) were investigated. Microscope examinations were carried out with SEM. Hardness, one of the mechanical properties, is determined by the Vickers method, which is a method of hardness measurement. According to SEM examination, the CrC phase in the Cu-MCs composed of coaxial grains were balanced. It has also been observed that the hardness increases with increasing CrC ratio. The wear behaviours of the produced CMs were analyzed with pin-on-disk wear test. According to this investigation, 50N and 75N loads were applied to the composite materials and wear depths, friction coefficient variation, wear diameter variation and weight loss were investigated at a slip speed of 0.4 m/s and a slip distance of 1200 m. According to these investigations, it was observed that as the ratio of CrC particle reinforcement increased, wear resistance amount increased regularly.
