Abstract
Laser cladding is an interdisciplinary process that uses laser technology, design and, production with the help of a computer, a positioning device equipped with software and, a material feeder with a nozzle. 17-4 PH stainless steel has wide
applications in the industry, including gas turbine blades. Due to the efficiency of these blades, after some time, due to contact with particles and environmental pollution, they will wear and corrode; therefore, due to the high cost of replacing the part, it must be rebuilt. In this research, the wear properties of 17-4 PH and Stellite6 steel claddings on 17-4 PH steel substrate were investigated. The results showed that the mass reduction due to the wear of the Stellite6 cladding compared to the substrate has decreased by about 88 and 93% in loadings of 6 and 54N, respectively. Also, the reduction in mass due to the wear of 17-4 PH stainless steel cladding as the substrate at the loading of 6N, which is reduced by 22% at the loading of 54N. The stainless-steel cladding and the substrate have more friction than the Stellite6 cladding. Also, the wear mechanism
of the stainless-steel cladding and the substrate is scratchy and sticky and, mechanism of the Stellite6 cladding is scratch wear at 6N load and sheet wear at 54N load.
