A long-acting nano-micro composite layer synthesis liquid and its preparation method

Abstract

The invention relates to long-acting nano-micron composite layer synthetic solution and a preparation method thereof. The synthetic solution is prepared from a main salt, a reducer, a main complexing agent, an auxiliary complexing agent, a buffer a, a buffer b, silicon carbide, magnesium oxide, a cationic surfactant, a nonionic surfactant, rare earth, a stabilizer, a promoter and deionized water.Compared with the normal conventional chemical composite plating solution, the synthetic solution has the advantages of high plating speed, stable performance of plating solution, no pollution and high economy. The synthetic solution can be recycled by only periodically replenishing loss; and the binding force of the synthetic solution and a matrix reaches up to over 400MPa, is 200MPa higher thanthat of the common alkaline self-decomposition plating solution and is 300Mpa higher than that of electroplating.

Description

technical field

[0001] The invention relates to the field of metal-ceramic alloys, in particular to a technology of metal-ceramic composite plating. Background technique

[0002] As we all know, metals, especially metal alloys, have superior physical and mechanical properties, such as certain hardness, excellent toughness and ductility, compactness, impact resistance, and pressure resistance. And ceramics have high hardness, superior wear resistance, corrosion resistance and so on. The combination of the two is the inevitable combination of advantages and the way to minimize their respective shortcomings, that is, cermet chemical composite plating. The composite layer ceramic alloy synthesis technology is transformed on the basis of self-catalyzed nickel-phosphorus alloy. Self-catalytic plating is a relatively new process technology.
