Abstract
Among several nanocoatings, Ti and B4C hard coating shows excellent wear performance in cutting tool operation. This hard nanocoating Implemented on GCI substrate using EB-PVD coating is to make them suitable for engine components and to act as a protective coating against surface wear and reduce the wear of the components. The wear test was conducted using Pin-on-disc equipment at the room temperature and surface roughness was measured using surface roughness tester.The wear parameters such as sliding speed and sliding distance were kept constant and the load is varied. Coating hardness was measured using Brinell hardness tester.The investigation shows that Ti, B4C coatings have significant effect on GCI sleeve. Also, the result shows that the coating of Ti, B4C improved the wear resistance of the grey cast iron.
