Abstract: А methodology was developed for constructing theoretical and numerical dependencies and algorithms for determining contact and wear parameters, including for gears with coatings. The asymptotic dependences of calculating the parameters of contact interaction and wear of elastic bodies with composite coatings are proposed. A computer program has been created that makes it possible to build a profile of the teeth of gears, determine the contact zone of the interacting teeth of gears, calculate the thickness of the worn layer, and take into account the location of fibers in the matrix of the composite material for wear parameters. The proposed approaches can be used in production processes to select materials when creating structural elements of machine parts.

Keywords: contact parameters, composite coatings, gears, asymptotic dependencies.
