| Summary: | Gear provides an important means of transmission in the automobile, and the service life of the gear teeth has a direct effect on how the engine performs. To enhance the strengthening performance of gear surface, three composite coatings were prepared in this paper by supersonic flame spraying technology, with nickel-based powder as the main material, and ceramic powder WC, TiO2 and Cr3C2 added to it respectively. Hardness tester, scanning electron microscope, X-ray diffractometer and other devices were used to comparatively evaluate the performance of the coatings. Then, static simulation was carried out for the coating. The results show that the coating containing Cr3C2 is superior to the other two coatings in densification and hardness. Finally, ANSYS software was applied to model the gear surface coating, revealing that the gear with Cr3C2 ceramic powder is advantageous over the coating with TiO2 particles. |
