ABSTRACT
The article examines the study of increasing the wear resistance of the cylinder-sleeve of a piston pump using the developed technology of plasma spraying. Wear-resistant and durable coatings of nickel, chromium, molybdenum and tungsten were obtained on the surface of the piston pump cylinder-sleeve. A graph of the dependence of the coating thickness depending on the surface hardness of the cylinder-sleeve is presented. According to the graph, depending on the hardness, you can determine the wear resistance of the coating surface of the cylinder-sleeve.
Keywords: piston pump, cylinder liners, plasma method, nickel, chromium, molybdenum, tungsten, wear resistance, coating thickness, hardness, graphical dependence
