Advantages of laser cladding technology
1, good bonding strength: laser cladding formed between the cladding layer and the plunger rod matrix is metallurgical bonding, bonding strength is much higher than the traditional coating process, can withstand large loads and complex conditions, to ensure that the cladding layer is not easy to fall off.
2, local treatment: the laser beam spot is small, energy concentration, can be local cladding on the specific parts of the plunger rod, does not affect the performance of other parts of the matrix, reduce the thermal impact on the overall structure, especially suitable for parts with high precision requirements.
3, optimize the material properties: by selecting the appropriate copper alloy powder, you can give the plunger rod surface such as good wear resistance, corrosion resistance, anti-friction and other properties. For example, some copper alloys have self-lubricating properties, which can effectively reduce the coefficient of friction between the plunger rod and the mating part, reducing wear.
4, high quality cladding layer: the laser cladding process is fast, the melting pool solidification speed is fast, can inhibit the formation of coarse grains, so that the cladding layer is fine, uniform composition, so as to improve the comprehensive performance of the cladding layer.
