Abstract

The invention provides an automotive fastener structure capable of improving corrosion resistance, and belongs to the technical field of fasteners. A coating (2) is arranged on an outer layer of a fastener body (1) of the automotive fastener structure capable of improving the corrosion resistance, the coating (2) comprises a half-gloss nickel layer (3), a full-gloss nickel layer (4) and a chromiumlayer (5), the half-gloss nickel layer (3) is arranged on the outer surface of the fastener body (1), the full-gloss nickel layer (4) is arrange don the outer surface of the half-gloss nickel layer (3), and the chromium layer (5) is arranged on the outer surface of the full-gloss nickel layer (4). The automotive fastener structure capable of improving the corrosion resistance is simple in structure and low in cost, corrosive process of outer substances can be blocked when a fastener is used, overall corrosion resistance of the fastener is improved, surface hardness is improved, the structuremeets requirements of various severe environments, the service life of the fastener is prolonged, and use safety is improved.

Description

technical field [0001] The invention belongs to the technical field of fasteners, and more specifically relates to a fastener structure for vehicles with improved anti-corrosion performance, and also relates to an electroplating method for fasteners for vehicles. Background technique [0002] Fasteners are a product with a very wide range of applications. In the use of fasteners, fasteners are often faced with harsh working environments, such as corrosion. However, the fastener products in the new technology will need to be replaced after being used for a period of time due to insufficient corrosion resistance, and there are often serious safety hazards. Contents of the invention [0003] The technical problem to be solved by the present invention is: aiming at the deficiencies of the prior art, provide a simple structure that can block the process of corrosion of external substances when the fastener is used, improve the overall anti-corrosion performance, improve the su...
