Influence of the particles velocity on the arc spraying coating adhesion

Abstract

The article deals with investigation of the influence of spray gun nozzle parameters on sprayed particles velocity and strength of coating adhesion. Four different arc spray nozzles were chosen for research. All variables of the spray process were constant except the air debit. The adhesion of coatings was tested. The results of the test showed the dependence of coating adhesion on particles velocity and contamination.
