Effect of a Multilayer Anticorrosion Coating on the Thermoelasticity of Round Plates

We propose a computational model of the distribution of temperature in a round plate with bilateral multilayer coatings. The solution of the problem of heat-conduction for plates with coatings and the regularities of variation of temperature across the thickness and along the radius are obtained. The influence of a two-layer coating on the thermoelastic state of a solid gas-turbine disk is established. It is shown that if we neglect the thermal characteristics of the coating, then we get overestimated values of temperature and underestimated values of thermal stresses.
