Abstract: Introduction.The article discusses the question of applicability of the calculation assessment method of resistance for details from gray cast iron after thermal diffusion hardening. The purpose of research is to check applicability of the calculated model for determination of intensity in case of the variable blanket hardness.Materials and methods.The model of intensity dependence on contact of two disks of friction gear is used in the research. Calculated determination of parameters is executed in two options: contact of the steel disk and di...
