Abstract

Plasma coating technology was applied to machine parts. During application, the jet formed hits the surface of the material and particles are deposited on the surface. In this way, layers of high thickness can be applied and thus revitalize worn machine parts. The paper examines the abrasion resistance of Al2O3 and Al2O3 phosphate layers applied to the base material using plasma technology. The abrasion resistance of the applied layers was tested using the ASTM G 65-85 method. The results of the tests on the loss of the material due to abrasion wear for the two types of coatings in each of the three tested samples are presented. The results of the loss of the material volume at different speeds of the test device wheel are also presented. The phosphate impregnated layer on Al2O3 samples showed significantly higher abrasion wear resistance.
