The scheme of the contact between cylindrical and spherical solids and soft coatings has
been considered. Using a nonlinear expression for the friction factor dependence on the
contact pressure and temperature of coating the relation of maximum contact tempera-
ture and contact pressure has been obtained. The critical speed values at which submelt-
ing one of the coatings occurs have been found. The results can be used for solving many
engineering problems because they are presented as simple formulae.
Key words
: coating, friction, heat release, contact pressure, contact temperature, wear.
