Summary:The article describes the technology of restoration of seats for bearings by plasma spraying based on the analysis of defects of the shaft of a centrifugal pump used in water industry. Based on the analysis of the wear of the shaft surfaces and the technological processes of restoration of the pump shafts, the method of plasma spraying of metal is selected. To achieve high adhesion, a multivariate experiment was conducted. The regression equation is described that describes the changes in the strength of the sprayed layer from the technological processing conditions. Recommended installation and technological conditions provide strength during plasma spraying.
