The Calculation of the Thickness of Thermal Spray Coating for Protection of Low Alloyed Steel when Heated under Rolling

Abstract

In scientific work has been developed a thickness calculation procedure of an aluminum thermal spray coating, sprayed on the low-alloyed steel surfaces in order to provide its effective protection at hight temperatures. The method is based on the calculations of the diffusion layer thickness with consideration of temperature change on the blank`s surface and on the dependence of the parameter (directly proportional to the diffusional coefficient) on the temperature.
