| Popis: | A Ni/ceramic composite coating (Ni-Cermets) was prepared on GH4586 nickel-based alloy by slurry method, and the morphology, phase composition of the coating was analyzed by XRD, SEM and EDS. The effect of the content of Ni on the microstructure and performance of the coating were investigated through the friction experiment, oxidation test and thermal shock experiment, respectively. It was found that this composite coating exhibited excellent oxidation resistance at 900 °C. Furthermore, Ni-cermets containing 47 wt.% of nickel (Ni47) showed the best resistance to oxidation, wear and thermal shock. The protection mechanism of this composite coating was different from those of traditional metallic coatings. |
