Abstract
The results of the study of the effect of defects in the deposited layer on the durability of deposited samples made of steel 08Kh14N5M2DL operating under friction conditions at high heating temperatures up to 800...900 °С and significant loads in the zone of tribological contact are presented. Defects in the deposited layer were pores, non-fusion and cracks. Defects in the friction tested specimens were determined by X-ray computed tomography. It has been established, that the wear resistance of the surfacing layer without defects decreases both with increasing test temperature and the load on the tribological contact. A particularly serious decrease in wear resistance was caused by the presence of microcracks in the deposited layer of the mesh. To a lesser extent, the amount of wear was affected by the presence of porosity in the deposited layer.
