金属噴鍍是一項具有一定經济价值的新工艺,它的应用范圍很广,可增补磨損尺寸,修复磨損零件和有縮孔、裂縫的鑄件,也可噴鍍耐热层(鋁)耐蝕层(鋅)和耐磨层。一般噴鍍在工件表面的鍍层温度很低(不超过80℃),而且不与底层材料发生焊合作用,也不与附着的基面起化合作用,所以基本不会产生过热現象、零件变形及基体組織性能的改变。在正常情况下,噴鍍各种金属的抗拉极限强度为9.5～29公斤/毫米~2,延伸率为0.23～1.43％,弯曲强度甚小,金属鍍层的密度
Metal plating is a new technology with certain economic value. It has a wide range of applications, which can increase the wear size, repair worn parts and castings with shrinkage and cracks, and can also be sprayed with heat-resistant layer (aluminum) (Zinc) and wear layer. Generally sprayed on the surface of the workpiece coating temperature is very low (not more than 80 ℃), and does not occur with the underlying welding material, nor with the attached base from the combined effect, so basically no overheating, parts Deformation and matrix changes in organizational performance. Under normal circumstances, the tensile strength of various metals sprayed to 9.5 ~ 29 kg / mm ~ 2, elongation of 0.23 to 1.43%, bending strength is very small, the density of the metal coating
