Impact Wear of the Protective Cr3C2-Based HVOF- Sprayed Coatings

Popis výsledku v původním jazyce

High velocity oxygen-fuel (HVOF) prepared CrC-based hardmetal coatings are generally known for their superior wear, corrosion, and oxidation resistance. These properties make this coating attractive for application in industry. However, under some loading conditions and in aggressive environments, the most commonly used NiCr matrix is not sufficient. The study is focused on the evaluation of dynamic impact wear of the HVOF-sprayed Cr3C2-25%NiCr and Cr3C2-50%NiCrMoNb coatings. Both coatings were tested by an impact tester with a wide range of impact loads. The Wohler-like dependence was determined for both coatings’ materials. It was shown that, due to the different microstructure and higher amount of tough matrix, the impact lifetime of the Cr3C2-50%NiCrMoNb coating was higher than the lifetime of the Cr3C2-25%NiCr coating. Differences in the behavior of the coatings were the most pronounced at high impact loads.
