Problems solved by technology

The micro-crack nickel plating process on the surface of plastic parts is: A. Metallization of plastic parts, B. Bright copper, C. Semi-bright nickel, D. High sulfur nickel, E. Bright nickel, F. Microporous nickel, G. Washing , H. bright chromium, I. washing, J. drying; although adopting this four-layer nickel-nickel electroplating solution to carry out electroplating on the plastic surface has improved the corrosion resistance of plastic parts to a certain extent in this technical scheme, yet the anticorrosion property of this process Corrosiveness still cannot be achieved with de-icing salts (CaCl 2 ) corrosive environment requirements, the high-sulfur nickel electroplating layer has local fogging phenomenon, in addition, due to the insufficient surface treatment of the plastic in this method, the deep plating ability of the coating layer is poor, and the coating layer is easy to become brittle. Grille, trim, door handle) after short service life
And about the technique of introducing micro-crack nickel, as Chinese patent application (publication number: CN101705508A) relates to a kind of electroplating solution and application thereof for micro-crack nickel electroplating, the main composition of this micro-crack nickel electroplating solution is as follows: nickel chloride: 180-260 g / l, acetic acid: 20-60 ml / l, ELPELYT MR: 80-120 ml / l, 62A: 1-5 ml / l, the evaluation of examples described in the patent literature is actually limited to hexavalent chromium plating , without mentioning trivalent chromium plating

Abstract

The invention discloses a nickel-chromium plating part and a manufacturing method thereof. The nickel-chromium plating part includes a substrate, a pretreatment coating, a base layer, a functional layer and a decorative layer. The pretreatment coating is deposited on the entire substrate, and a copper plate layer is formed on the pretreatment coating; the base layer is formed on the copper plate layer; the functional layer is formed on the base layer and includes a low potential nickel layer and a microporous nickel layer formed on the low potential nickel layer; and the decorative layer is formed on the microporous nickel layer and is a trivalent chromium coating or a hexavalent chromium coating. Based on the micropores on the part surface and chrome plating technology, the low potential nickel layer is added to improve the corrosion resistance of the product, especially the corrosion resistance of trivalent chromium plating product, so as to promote the large scale popularization and application of the trivalent chromium product, which has better environmental protection performance.

Description

technical field [0001] The invention relates to a workpiece with a surface coating structure and a manufacturing method thereof, in particular to a nickel-chromium plated part and a manufacturing method thereof. [0002] In this application, the potential difference is the difference between the standard potentials measured by taking each of the two adjacent layers as a whole. Background technique [0003] The European market has increasingly stringent environmental protection requirements, and the main engine manufacturers have higher and higher requirements for electroplating corrosion resistance. At present, trivalent chromium electroplating cannot meet the corrosion requirements of specific environments (at the same time, it can meet the salt spray test 80h and Russia Mud test 336h). [0004] In the electroplating industry, the method of firstly plating double-layer nickel or triple-layer nickel and then chromium plating is generally used to improve the anti-corrosion a...
