|Abstract:||Dense, with good adhesion to the substrate, hard, wear-resistant coatings from the powder of Al2O3 were obtained on the surface of the steel (STE255) by using the cumulative-detonation device. The results of investigations of the structure and physico-mechanical properties of the coatings by using scanning, optical microscopy, X-ray phase analysis, microhardness and tribological tests are presented. It was found that optimization of plasma spraying to helps reduce the porosity of coatings of Al2O3 less than 1 % and to increase the hardness of them to 1250 HV0.3. The tribological investigations have shown that the coatings of Al2O3 significantly increase the wear resistance of the sample STE255 and provide a low ability to wear out the coating|
