Sažetak
Abrasion resistance of thin hard coatings is a key property for their application. The paper compares the abrasion resistance of two coatings produced by plasma- assisted chemical vapor deposition (PACVD): gradient coatings TiN/TiCN and multilayer coatings TiN/TiBN, which were applied to tool steel EN DIN X37CrMoV5-1. The coatings were tested for roughness, microhardness, and adhesion. Abrasion resistance was tested using the "dry sand - rubber wheel" method according to ASTM G- 65 and micro-abrasion wear was tested using a calotester device. In the calotest, the coating is worn by rotating a hardened steel ball made of steel EN DIN 100Cr6 coated with diamond paste. At the place of calotest wear, a spherical crater with a circular rim on the outer edge and the bottom of the crater is formed in the substrate material. The ratio of the outer and inner diameter of the circular rim around the crater determines the thickness of the coating. The outer diameter of the crater can also be an indicator of resistance to micro abrasion. By carrying out a series of calotests of different duration, from 10 s to 60 s, craters are created in coating and substrate. The diameter of craters were increased with the prolongation of the test. The paper compares the rate of wear on the same samples, determined according to both methods of abrasion resistance testing.
