Description

technical field

[0001] The invention relates to a surface treatment technology, in particular to a metal nanocomposite electroplating process. Background technique

[0002] We know that nanocomposite electroplating layer can be obtained by adding nanoparticles into the electroplating solution and co-depositing them with the matrix metal under agitation. Based on the particularity of nanoparticles, the prepared composite coating will exhibit many unique properties. These properties include: hardness, bonding force, corrosion resistance, wear resistance, high temperature oxidation resistance, etc. At present, the research on the nanocomposite nickel plating process at home and abroad is mainly to add inorganic non-silver nanoparticles, such as Si and SiO, to the plating solution. 2 , SiC, Al 2 o 3 etc., so as to obtain some functional coatings, such as: high temperature resistant coating, wear resistant coating, corrosion resistant coating, etc.
