| Abstract: | In the plasma spray rapid tooling(RPST), 3D free curved surface is usually sprayed on, using metal powder which is heated and accelerated by a plasma jet, then beats on the substrate to form the spray coating with some porosity. An algorithm for creating prism elements of coating based on the outer normal vector is proposed. The substrate was divided into the tetrahedral elements by commercial CAE software, The temperature field in the 3D plasma sparay coating is simulated by using the homogenization mathematic model of temperature field on macro-micro scale, and the tetrahedral elements and the prism elements. |
