| Abstract: |
| The work investigates the compositional and structural changes of NiCr/Cr3C2- BaF2/CaF2 coatings under high temperature oxidation, with emphasis on the effect of oxidation on the mechanical and tribological properties of the coatings which were prepared by HVOF and oxidized at 700，800 and 850 ℃. With the aid of scanning electron microscopy, X-ray diffractometer, microhardness tester, tensile tester and high temperature tribometer, the microstructure, composition and mechanical and tribological properties of the as-sprayed coating were compared with those of the oxidized coatings. One specific, frictional wear test was carried out on a high temperature ball-on-disk tribotester (UMT-Tribolab). The results of previous studies have shown that the coating wears most severely when tested near 300 ℃. This temperature point was chosen to investigate the frictional wear performance of the coating before and after the oxidation treatment, based on the most demanding frictional wear environment. |
