GA/T9798—2005/IS01458.2002
Decorative coatings with no rust, with rust-proof layers and without light layers are suitable for use in areas where the coating has no rust or corrosion, and the requirements for discoloration are not high. The corrosion resistance depends on the type and thickness of the coating. Generally speaking, the protective performance of multi-layer coatings is better than that of single-layer coatings. F
1 Scope
(11/T9798—2005/1801458,2C02 Nickel electrodeposition of metal cover
This standard specifies the general requirements for decorative and protective coatings on steel, alloy, copper alloy and aluminum alloy, as well as the requirements for collector coatings on iron and zinc alloy, the identification of the types of coatings, and the selection of coatings for fuel components under corresponding service conditions. |tt|| The standard does not specify the surface state of the base metal before plating. This standard does not apply to the lock layer on the unformed plate, strip, cut material, nor is it suitable for the layer on the solid or dense elastic layer. GL/197U7 stipulates the requirements for the electroplating layer. /T1260 has already determined the requirements for the continuous + chromium, key + chrome + slightly charged layer on the material. GB/T12$32 and G1/T1137S have respectively determined the requirements for engineering chrome, 2 Normative references

7.4 The strength of the structure
Therefore, the layer and the base and the missing layers should stand on the platform for a long light, and can pass the 27 complementary test or heat test: there should be no cavity between the layer and the body and the total number of each promise, and the office is separated. It is determined that the original price of the town is formulated by the state industry production in the south of the table 5

7.5 Towards accelerated cool salt true (Ca5> and acetylene salt spray (AASS) candlestick test cell silver parts should be tested according to the corresponding service parts number through a degree record test specified in Table 6, G/T10125 small corrosion test method: Any special test to be adopted should be required by the parties. In order to ensure the effective application of the coating, the degree of test should be determined according to the use of the coating. The test object duration, but the experimental duration and the service life of the plated parts are very small. After a certain corrosion test, the test piece should be inspected and evaluated according to the provisions of GB/T6461. Its grades are 0 and 19. The surface layer is relatively close to the previous layer. If it is selected, the relevant additional tests and actual applications are as follows: Table 6 Isolation test under the corresponding service parts number

inch Xie bottom number layer busy, the elongation of the multi-layer nickel flat book nickel should be tested according to the provisions of the appendix, and should meet the provisions of Table 5 before 1.8 Pre-heat treatment for stress elimination
When the purchaser has specified that the tensile strength of the steel is greater than or equal to 1000MPa (31HKU>, the tensile stress caused by the cold forming process should be eliminated before the heat treatment. The process and type should be specified by the purchaser, or the appropriate process and type specified by the purchaser in GK/11934. Steel parts with oxide scale should be removed before electroplating. For high strength parts, alkaline chemical method and alkaline barrier method can be used for removal. Mechanical methods can also be used to avoid oxygen generation during the removal process. 7. Hydrogen embrittlement treatment
For steel parts with tensile strength of 1K MPa (31HRC) or more and surface hardened parts, they should be treated according to GT/T i (or the process and type specified in the ancient regulations need to eliminate hydrogen embrittlement.
The teaching room of the elimination room should be difficult or the test method specified by the demand party is up to the determination, such as SU1C87. The residual hydrogen in the test method of the component should not be bent before eliminating oxygen embrittlement. Note that the type of summer layer specified in this standard is relatively poor. If the left is used, the tensile strength is greater than 1M. The signal well has been treated with potential. If it is only hydrogen, it should be treated naturally. The demand party should pay attention to the heating but it may change color, which is more effective. Of course, daily sampling
