Abstract

The invention discloses a compound plating solution for obtaining a nano compound plating layer with resistance to abrasion and high temperature oxidation and a plating method thereof. The compound plating solution comprises the following components: 200 g / L to 500 g / L of Ni(NH2SO3)2*4H2O, 5 g / L to 30 g / L of NH4Cl, 10 g / L to 80 g / L of H3BO3, 0.05 g / L to 5 g / L of C12H25SO4Na and 5 g / L to 8 g / L of nano zirconia granule. The whole plating process is carried out in an ultrasonic field; the strong stirring action and the ultrasonic cavitating effect of an ultrasonic wave facilitate well dispersingof ZrO2 nano granules in the nano compound plating layer, enable the structure of the compound plating layer to be thinner and denser and enhance the abrasion resisting performance of an oxidation film; and the uniformly distributed ZrO2 nano granules not only facilitate the grain refinement of oxidation film, but also improve the growing mechanism of the oxidation film, thereby enhancing the resistance to high temperature oxidation of the compound plating layer. The plating method has the advantages of simple process, low cost and convenient popularization and application.

Description

technical field [0001] The invention relates to the technical field of metal surface protection, in particular to a composite plating solution and an electroplating method for obtaining a wear-resistant and high-temperature oxidation-resistant nano composite coating. Background technique [0002] With the development of industry, more and more mechanical parts work under complex and harsh conditions, so the requirements for the surface performance of parts are getting higher and higher. As an effective surface protection measure, surface coating technology has emerged as the times require. has been widely used. Among many coating materials, nickel coating is the most widely used due to its excellent corrosion resistance and good processing performance. However, with the advancement of science and technology and the increase of market demand, the existing single nickel coating can no longer meet the requirements.
