The acceptance should be carried out under good light or artificial lighting. The components can be inspected visually. When necessary, a magnifying glass can be used for inspection. 1) Before the components are coated, the separation of the components and the metal parts should be carried out in a proper manner. 6) When the components that cannot be separated or are inconvenient to be separated are assembled by pressing, welding, steel welding, lap welding, spot welding and other inseparable methods, they can be replaced by electroplating, sugar capsule plating or spot welding. 5.1 Quality requirements for special-shaped parts with complex inner cavities before plating. Before plating, there must be no residual solder and molten metal. During the blasting process, there must be no gas traps and welding wires. 5. Degreasing and rust removal of metal parts before plating 5.1 Before plating, metal parts should be free of oil seals, paint, metal dust, machine scratches, dark-colored velvet, etc. 5.E.2 For castings that have not been machined, forgings and natural emulsions, the ultimate tensile strength of the material should be reduced by 10M. H/T 12611--2008 5.6.3 After spraying, there should be no residual scale, rust, oil marks, fingerprints, etc. on the surface. For high-strength steel parts that have been sprayed, the inner ring should be slightly (pre-treatment). 5.7 Requirements for heat treatment to eliminate residual stress before plating of parts 7. After mechanical machining, cold forming and straightening, the parts should be treated according to the conditions specified in Table 1. When the maximum strength of the material is greater than 0.50MPa, except for the parts shown in Table 1, the heat treatment should be carried out to eliminate residual stress according to the conditions specified in Table 1.
