Process Parameters Optimization of Plasma Spraying Nanostructured Coating Based on Particle Swarm Optimization Algorithm
Abstract:
Process parameters of plasma spraying nanostructured Al2O3-13%TiO2 (mass fraction) coating were optimized based on particle swarm optimization (PSO) algorithm. BP neural network was applied to compute fitness of PSO algorithm. A BP neural network model was built. Process parameters of coating were optimized based on PSO algorithm. The results shown that maximal bonding strength was 33.08MPa. Process parameters of plasma spraying nanostructured Al2O3-13%TiO2 (mass fraction) coating were obtained. The results were superior to design of orthogonal optimization. It provided definite reference for selecting the best process parameters of plasma spraying nanostructured Al2O3-13%TiO2 (mass fraction) coating.
