The article describes the methods of applying of protective coatings to the rotor of downhole drilling motors. The analysis of the effectiveness of methods of applying of protective coatingswas carried out. The article shows that the transition to gas-thermal spraying method with laser melting allows to achieve high technical and technological results in comparison with other methods.
