Problems solved by technology
[0005] The most important thing in electroless plating is the catalytic liquid with self-catalytic ability. The existing catalytic liquid process still has disadvantages such as high cost, single functional component, fast corrosion speed, and low hardness. It is more difficult, the plating speed is slower, and it is difficult to meet the production requirements. Therefore, it is urgent to improve the catalytic solution of the existing technology to improve production efficiency, increase the quality of the coating, reduce production costs, and reduce environmental pollution.

Abstract
The invention discloses a nano, easy-to-weld, high-hardness, wear-resistant, corrosion-resistant and decorative alloy catalytic liquid and a preparation method thereof. The nano, easy-to-weld, high-hardness, wear-resistant, corrosion-resistant and decorative alloy catalytic liquid is compounded by nickel, zinc, rare earth elements and the like as basic raw materials, a lubricating, easy-to-weld, high-hardness, wear-resistant, corrosion-resistant, bright-thickness and accurate-thickness nano-alloy layer can be obtained on the surface of metal by high-temperature catalysis, and the nano easy-to-weld, high-hardness, wear-resistant, corrosion-resistant and decorative alloy catalytic liquid has an appearance decoration effect on the premise of high hardness, high wear resistance, high corrosionresistance and the like, the compact conversion alloy layer formed by catalysis can be stable in a severe environment, and the appearance of the alloy layer can be kept unchanged for a long year.
Description
technical field [0001] The invention relates to the technical field of electroless plating solutions, in particular to a nanometer easy-to-weld high-hardness wear-resistant anti-corrosion decorative alloy catalyst solution and a preparation method thereof. Background technique [0002] It is well known that the metal surface is easy to rust, so in order to facilitate people's daily life, at present, the commonly used metal surface treatment processes mainly include phosphating, impregnation, electroplating direct current, oxidation blackening, dacromet and other processes, but each technology is different. It has its weaknesses, and the most important thing is that it does not meet the requirements of environmental protection. [0003] At present, the most commonly used metal surface treatment in the market is the electroplating coating. During the electroplating process, the metal ions in the plating solution are reduced to metal atoms by electrode reaction under the action...
