Abstract

The invention belongs to the field of microwave communication devices, and discloses a method for enhancing the surface of a microwave communication device through low-temperature molten salt electroplating of a Ni-WC composite layer. The method comprises the following steps: 1) drying and grinding inorganic salts LiNO3, NaNO3, KNO3, Ca(NO3)2, NaNO2, KNO2, LiCl, NaCl, KCl and CaCl2 to obtain a mixed salt, heating and melting the mixed salt into a liquid at 100 DEG C, pouring the liquid into an electroplating tank, and heating to keep the liquid. According to the invention, the prepared composite electroplating solution has the melting point of 60 DEG C, and in order to achieve the high fluidity of an electrolytic solution, the actually selected electroplating temperature is 100 DEG C, andthe low-temperature electroplating at 100 DEG C can substantially reduce the energy consumption compared with the traditional molten salt electroplating at 150-500 DEG C, so that the actual operationis simple and energy-saving so as to achieve the purposes of electrolysis under the low-temperature mild condition, simple and mild reaction conditions, cleanness and no pollution, and the Ni-WC composite plating layer obtained through electroplating has the advantages of being resistant to abrasion, high in hardness, self-lubricating, resistant to acid and alkali corrosion, high in electric conduction and heat conduction coefficient and the like.

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 ...
