INFLUENCE OF COATING DESTRUCTION ON TRIBOLOGICAL CHARACTERISTICS OF FRICTION UNITS

Destruction of tribological coatings during operation is a limiting factor, the implementation of which leads to the loss of the specified properties by the friction unit. On the example of a two-layer coating of diamond-like carbon with an intermediate layer of titanium aluminum nitride, a case of its destruction due to defects on the surface was considered. The destruction of the coating leads to a significant increase in the coefficient of friction and the intensity of wear, since the abrasive wear particles formed in this case stimulate the process of destruction of the surface layers in contact with the bodies.
