Abstract
Physical vapor deposition (PVD) coatings are utilized to improve the service life of tools and components. Depending on the application, these tools and components undergo various stress types. For instance, in cold forging applications the tools predominantly endure cyclic impact loads. Previous studies on fatigue response of PVD coatings under cyclic impact loads focus on Ti-based or CrN coatings and attribute the coating fatigue behavior to the elastic-plastic deformation of the substrate. However, the influence of the coating chemical composition on the impact fatigue behavior, particularly for CrAlN coatings, is rather missing in the literature. The current work aims to investigate the influence of Al content on the impact fatigue response of CrAlN high-power pulsed magnetron sputtering (HPPMS) coatings. CrAlN coatings with low, medium and high Al content were deposited on HS6-5-2C steel substrates. The chemical and phase compositions were determined by electron probe microanalysis and X-ray diffraction analysis, respectively. The elastic-plastic properties of the coatings were determined by nanoindentation test. Rockwell C indentation test was used to analyze the adhesion between coating and steel substrate. The coated samples were subjected to a cyclic impact load of F = 1000 N and frequency of f = 50 Hz during the impact tests with N = 0.1 × 106, 0.5 × 106, 0.75 × 106, and 106 impacts. Finally, the fatigue behavior of the CrAlN coated steel substrates was analyzed inside the impact imprint area for fatigue cracks and plastic deformation using scanning electron microscopy and confocal laser scanning microscopy, respectively. Additionally, the impact fatigue response of the uncoated steel substrate was also taken into consideration. CrAlN/steel compounds showed better impact fatigue response as compared to the uncoated steel substrates. Moreover, the increase in Al content resulted in an improved impact fatigue behavior for the CrAlN/steel compounds.
