Abstract:
This study designs a pulsed magnetic field assisted supersonic plasma spraying (PM-SPS) device. The instrument is divided into magnetic field generation and spraying modules, and they are connected by a dual control system and professional fixture. The PM-SPS system is simple to operate and has no contact with the spraying process. In addition, it can achieve high field intensity and stable pulse frequency in a short time. It has a strengthening effect on the whole coating forming process. The porosity, roughness, hardness, and tribological properties of the coatings prepared using the PM-SPS system were improved. The reported experiments and results can be generalized to other coating applications, which require high quality surfaces.
