Abstract

Gas-dynamic deposition of mechanically synthesized hybrid powders based on a nanocrystalline matrix AMg2 strengthened by nanocrystalline graphite and micro-sized Al2O3 particles is performed. The effect of Al2O3 content in a charge, varied in the range of 10–90 wt.%, on the grain size composition of the synthesized hybrid powder is studied. The structure-phase composition of synthesized hybrid powders and formed coatings was studied by X-ray diffraction analysis. Quantitative estimates are obtained of the Al2O3 content in the hybrid coatings formed. The influence of Al2O3 content in the powder on the efficiency of the gas-dynamic spraying of a hybrid coating is determined. The rational content of Al2O3 in powder is determined ensuring efficient hybrid coating deposition.
