Abstract

The invention belongs to the field of microwave communication devices, and discloses a method for enhancing the surface of a microwave communication device by electroplating a Ni-WC composite layer with a low-temperature molten salt, comprising the following steps: 1) adding an inorganic salt LiNO 3 、NaNO 3 、KNO 3 , Ca(NO 3 ) 2 、NaNO 2 、KNO 2 , LiCl, NaCl, KCl, CaCl 2 Dried and finely ground to make mixed salt, heated and melted at 100°C to become liquid, then poured into the electroplating tank and heated to keep it liquid. The composite electroplating solution prepared by the present invention has a melting point of 60°C. In order for the electrolyte to have higher fluidity, the actual selection of the electroplating temperature is 100°C. It will greatly reduce energy consumption, make the actual operation simpler and more energy-saving, so as to achieve the purpose of electrolysis under low temperature and temperature conditions, simple and mild reaction conditions, clean and pollution-free, and the Ni-WC composite coating obtained by electroplating has wear resistance, high Hardness, self-lubrication, acid and alkali corrosion resistance, high electrical and thermal conductivity and other advantages.

Description

technical field [0001] The invention relates to the technical field of microwave communication devices, in particular to a method for enhancing the surface of microwave communication devices by electroplating a Ni-WC composite layer with low-temperature molten salt. Background technique [0002] At present, microwave communication connecting devices and corresponding cable joints are made of metal. In order to ensure good electrical and physical properties, the surface of connectors and cable joints needs to have wear resistance, high hardness, self-lubricating, acid and alkali corrosion resistance, and high electrical conductivity. Features. In order to fully improve the performance of the above products, it is usually possible to deposit a layer of anti-wear and corrosion-resistant metal coatings on their surfaces by electroplating, such as: single metal nickel Ni, or metal single gold Au, but the cost of nickel Ni and gold Au is relatively high. High, while its hardness ...
