Introduction of Metal Spray Welding Plunger:
The spray metal grooved plunger produced by our company adopts oxygen and acetylene spray welding technology to spray nickel-based alloy powder onto the surface of the substrate after surface roughening and activation, and then heats it to the temperature range where the solid-liquid phase line appears, so that the alloy material is melted and laid flat to obtain a surface-modified welding layer, thereby changing the wear resistance and corrosion resistance of the workpiece. The thickness of the spray welding layer of the spray metal grooved plunger is determined according to the actual needs of the working conditions, with a minimum thickness of 0.203mm. The welding layer and the substrate metal are metallurgically brazed, and the bonding strength between them can reach 200~300Mpa. The nickel-based alloy powder in the spray metal grooved plunger has good bonding strength with the substrate, good impact resistance, high hardness, wear resistance, corrosion resistance, and oxidation resistance up to 650℃, which can form a good friction pair with the pump barrel.
Features of Spray Metal Grooved Plunger:
The plunger of the down hole pump plungers adopts oxyacetylene flame spraying technology to spray nickel-based alloy powder onto the surface roughened and activated substrate. Subsequently, the alloy material is heated to a temperature range where the solid-liquid phase boundary appears, so that the alloy is melted and a uniformly distributed surface modified welding layer is formed. This process improves the wear resistance and corrosion resistance of the workpiece. The thickness of the flame spray layer of the spray metal grooved plunger is determined according to the actual use, and the minimum thickness is 0.203 mm. The welding layer of the spray metal grooved plunger forms a metallurgical brazing joint with the base material, and the bonding strength is as high as 200-300MPa. The nickel-based alloy powder used in this process is a high-hardness alloy powder with excellent self-fluxing, wettability and flame spraying properties. It has the characteristics of wear resistance and corrosion resistance.
