Tribological studies of aircraft engine parts made by selective laser melting

Abstract

This paper presents the results of comparative tribological tests to assess the resistance of additive metal parts to fretting wear. The microstructure of the products made by selective laser melting is studied. Tribological tests were carried out on a friction machine. It is experimentally shown that the tribological properties of products printed from metal, regardless of the printing angle in the construction chamber, differ from products made using traditional technology within 7%.
