【 摘 要 】

Results of stochastic modeling of lamellar structure formation and characteristics (microstructure, porosity, roughness) of ceramic coatings made of corundum powders (α-phase of Al2O3) are given in conditions typical for atmospheric plasma spraying (APS), and also detonation and supersonic flame spraying (HVOF). Comparison of characteristics of coatings for two model splats morphologies at their random laying on the base surface is presented.
