Numerical simulation the temperature and stress of the SHS reactive flame spray coatings which were cooled in air and sand from a high temperature to room temperature (25°C). The distribution of temperature and stress of the coatings were discussed. The results show that the cooling velocity of air-cooled product is fast than that of sand-cooled product; temperature distribution of sand-cooled product is more uniform than that of air-cooled product in the process of cooling; the stress state of air-cooled coating is tensile stress state, while the stress state of sand-cooled coating is compressive stress state; the stress distribution and strain situation are close relative to temperature distribution, heat emission speed and geometric shape of products in process of cooling; the smooth geometric shape of the product, uniform temperature distribution and heat emission speed are beneficial to improve the state of residual thermal stress; the stress and strain state of sand-cooled coating is better than that of air-cooled coating.
