Abstract

The results of stochastic simulation (computer-aided design) of a layered structure formation and functional characteristics (porosity, roughness, adhesion) of metal coatings based on titanium aluminide powders (γ-phase TiAl) under conditions typical of atmospheric plasma spraying are given. Taking into account the stable formation of a metal splats and titanium aluminide coatings, as well as minimum porosity and maximum adhesive strength of coatings, the optimal plasma spraying mode has been obtained: the particle velocity U p = 250 m/s, the particle temperature T p ≤ 2050 K, the particle diameter D p = (30 ± 10) μm.
