Problems solved by technology

However, there are the following problems in the traditional ordinary vacuum coating equipment and process methods: (1) imitating the water electroplating process to directly plate pure nickel film and pure chromium film on the copper substrate successively, it is easy to cause excessive stress between the nickel film layer and the chromium film layer. (2) Use a fixed composition target as the intermediate transition layer, for example, a target containing 50% nickel and 50% chromium can be used to deposit the intermediate transition layer
However, this kind of film structure only

Abstract

The invention relates to a device for manufacturing a nickel-chromium composite plate by using vacuum arc ion plating to replace electroplating and a method thereof, and is characterized in that the device of the vacuum arc ion plating and the method are utilized to replace water electroplating to sequentially prepare the nickel-chromium composite plate composed of a pure nickel film, a nickel-chromium gradient transition film and a pure chromium film on a copper substrate; the device for manufacturing the nickel-chromium composite plate by using the vacuum arc ion plating is of a vertical cylindrical shape or a regular polygon; arc target sources are evenly distributed around a vacuum chamber wall; a controllable mechanical baffle plate is arranged in front of each target source; a planetary type work rest with rotation and revolution is arranged in the middle part of a vacuum chamber; the technical process of a filming operation comprises three stages that are preliminary treatment, the filming operation and post treatment. The device and the method simplify the process flows and the operation links, increase the work efficiency, fully replace the traditional electroplating technology to coat a wearproof anticorrosion decoration coating on a coppery water heating component, and thoroughly eliminate the environmental pollution problems in the electroplating.

Description

technical field [0001] The invention relates to the technical field of vacuum coating, in particular to an equipment and method for preparing nickel-chromium composite coatings on copper substrates by vacuum arc ion plating instead of water electroplating. Background technique [0002] The method of plating an anti-corrosion and wear-resistant nickel-chromium composite coating on a copper substrate has a large number of applications in industrial products, and its typical products are such as plumbing equipment components. The production process of high-grade plumbing parts is: copper casting molding, surface polishing, nickel plating first, and then chrome plating. The function of the nickel-chromium coating is to improve the corrosion resistance, surface wear resistance and surface brightness of the product. The quality of the surface film directly determines the grade, price and service life of the product. For a long time, the surface coating process of water heating e...
