ESTIMATION OF ADHESIVE CHARACTERISTICS OF CONTACTING MATERIALS WITH COVERINGS

G.I. Kostyk, O.M. Melkozerova

In the given work the technique, for a rough estimate of characteristics of adhesion of contacting materials with coverings is offered. It is shown that values of energy of adhesion for pairs of the materials, received with application of various theories, slightly differ from each other. Communication between durability of coupling and energy of adhesion that allows to define adhesion characteristics practically for any materials is revealed. It is shown that durability of coupling is connected with thickness of a covering inversely proportional dependence. As an example calculation of energy and force of adhesion, and also durability of coupling for a steel 38ХС and titanic alloy ВТ14 with a number coverings is offered.

Keywords: energy of adhesion, durability of coupling, force of adhesion.
