The influence of technological conditions on the strength characteristics of plasma-sprayed
coatings of aluminum oxide powder with a fraction of 40–63 [μm], modified with a titanium oxide
Nano powder with a particle size of 40–50 [nm], was studied. As independent variables (technological
factors), which are the most significant and have the greatest influence on the strength characteristics
of the coatings, there was chosen lens current, arc current, and the position of the solenoid relative to
the nozzle. The adhesion strength and tensile strength of the coatings were adopted as optimization
criteria. Mathematical models of the adhesion strength and the tensile strength of plasma coatings of
aluminum oxide was obtained. As a result of multi-criteria optimization using the obtained
mathematical models, the optimal combination of the levels of controlled factors was determined.
