Abstract

The article is devoted to the study of wear resistance of austenitic stainless steel grade 03Kh17N14M3, manufactured using selective laser melting technology. The large temperature gradient during the selective laser melting process leads to the formation of an anisotropic microstructure. The grains have a highly developed substructure consisting of columnar dendrites, the orientation of which in the synthesized material is an important factor affecting the properties. Measurements of the microhardness HV at an indenter penetration depth of several micrometers revealed anisotropy: the microhardness in the layer plane is 27% higher than in the cross section. The indentation hardness HIT in the layer plane and in the cross section do not differ with increasing indenter penetration depth to tens of micrometers, i. e. the anisotropy of hardness becomes imperceptible. Wear tests revealed a significant inhomogeneity in the wear resistance of the material under study. In the plane of the layer, wear resistance is on average 40% higher than in the direction of sample synthesis. The results of the studies carried out can be used in the development of technologies for layer-by-layer synthesis of parts with increased wear resistance of contact surfaces.
