Diamond-like carbon (DLC) coatings are currently used in many areas of the economy. Due to their unique properties, such as high hardness, low friction, and high wear resistance, are also used in industry, especially on machine parts exposed to increased wear. The paper presents the results of operational tests of diamond-like carbon coatings deposited in the physical vapor deposition (PVD) process on samples made of 4H13 stainless steel. The properties of DLC coatings were assessed based on microstructure analysis, nanohardness and roughness measurements, and tribological tests. The results obtained during the tests showed that using diamond-like coatings significantly improves the tribological properties. In addition, the coatings are free of pores and microcracks. In addition, DLC layers are characterized by high nanohardness and low roughness. This type of coating can be used on surfaces of machine parts.
