ABSTRACT
It is known that the service life of oilfield machines and mechanisms is to a certain extent determined by the operability of friction units, the operation of which, as a rule, occurs under severe conditions (heavy loads, abrasive aqueous medium, etc.). It is also known that the determining parameters in the units of machines and mechanisms (lubricated with water) with polymer elements are specific load, sliding speed and relative clearance. In the field, these factors affect the coefficient of friction together, therefore, the study of their influence [µ = f (p, ʋ, ψ)] on the coefficient of friction is possible only with the use of mathematical modeling. We have studied the nature of the joint influence of the main operating parameters on the performance of the ison thermoplastic elastomer plain bearings.
Keywords: Operation, polymer elements, field conditions, bearings, sliding speed.

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
