Table 3:The corrosion-resistant experimental result of zinc layers
The beneficial effects of the invention are as follows:Copper alloy of the present invention adds deoxidier coverture by fusion process and refining process causes
Copper alloy fused solution alloying fully, improves copper alloy mechanical strength, as stamping tool supportive body with good carrying axle
To pressure, improve its service life, it is laser impact intensified after, rush stick body surface face and produce intensive uniform misconstruction, dislocation
Increase in density, improves its superficial layer intensity, and hinders its dislocation motion when bearing pressure, reduces the machine cracked
Rate, the dislocation of its surface is intensive to be had and effectively improves its corrosion resistance, weatherability, at the built-up welding of the stick that liquidates body stamping press end face
The overlay cladding that reason is formed to rush stick end its hardness heat-resisting quantity and is improved significantly so that punching press service life extends, and
And easily repaired, bead-welding technology also makes overlay cladding and copper alloy associativity good.
