HIGH STRENGTH COATING TESTING LAYERS ON MACHINE PARTS ON THE ABRASIVE WEAR
HIGH STRENGTH COATING TESTING LAYERS ON MACHINE PARTS ON THE ABRASIVE WEAR

Summary/Abstract: This study was conducted plasma technology application of coatings on machine parts. During the application the formed spray hits the surface of the material and the particles are deposited on the surface. In this way, the layers can be applied with a high thickness, and thus revitalized worn machine parts. Studied was the resistance to abrasive wear two types of layers: А12О3 and the А12О3 with phosphates, applied on the base material using plasma technology. Resistance to abrasive wear of coating was investigated by the method ASTM G 65-85. Shown are the result of material volume loss due to abrasive wear of the two aforementioned types of coatings on three samples. It was also presented the results of the material volume loss at different wheal revolution per minute. The layer impregnated with phosphates showed significantly greater resistance to abrasive wear.
