Spray Welded Plunger

1. The spray welding layer of metal spray welding plunger is bonded to the base metal through metallurgical brazing, and the bonding strength can reach 200-300MPa, which exceeds the ordinary coating and can be used for a long time without peeling. 2. The metal spray welding plunger has high hardness, corrosion resistance and oxidation resistance, which is conducive to extending the service life of the plunger under various working conditions. 3. The metal spray welding plunger has good oxidation resistance and is suitable for the transportation of various high-temperature and corrosive media.
