摘要：

This study studied the tribological properties of PVD AISI 4140 low - alloy TiN coated and reported. The morphologies before testing are assessed with a laser confocal microscope and XRD. Three tests are conducted per sample: the rotating, scratch, and reciprocation tests. The contour of counter bodies and wear scares are studied and reported. The wear scares are also further studied using the SEM-EDS chemical analysis to study the amount of wear that has occurred. The results showed a change in roughness and waviness after coating. In the reciprocating tests showed a high degree of spalling on the TiN sample is observed with a higher wear volume compared to the substrate. However, a lower coefficient of friction is observed. This is similar to the rest of the tests.
