The practical experiment of electroless nickel plating began in 1946. At that time, Brownler of the United States was studying synthetic oil when he stumbled upon the phenomenon that sodium hypophosphite could reduce nickel. He grasped this phenomenon and studied it deeply, and in 1947, he issued the process of electroless nickel plating.
In 1953, Brownler published a paper in the American "Metal finishing". He introduced the physical properties of the chemical deposited nickel layer, and pointed out that it was actually the co-deposition of nickel-phosphorus alloy, so the obtained nickel layer was harder than ordinary nickel.
In 1954, electroless nickel plating developed from depositing only on ferroalloy substrate to depositing on non-ferrous metals.
In 1955, Pippistin published a paper on the deposition of chemical nickel on nonmetals in Metallic finishing. It indicates that good coatings can also be obtained on synthetic resins, ceramics, glass, wood and other materials. However, due to the poor binding force, it failed to attract the attention of the industry, delaying the application of this technology.
It was not until 1958 that industrial electroless nickel plating was used in actual production.
In 1959, West published a paper on the deposition of chemical nickel on carbon. However, until 1968, the electroless nickel plating process was dominated by high temperature.
In the late 1960s, Hiroshi Ishibashi of Yoshihiro University of Technology in Japan made a systematic study on electroless nickel plating and published a series of papers on "Metal Surface Technology" in Japan until the normal temperature electroless nickel plating process was developed. This process was successfully developed in 1968 and published in Volume 21 of the Japanese Journal of Metal Surface Technology in 1970.
Since then, electroless nickel plating has been widely used in non-metallic electroplating and other industrial fields. Because it has more advantages than electroless copper plating, especially in non-metallic electroplating, its excellent stability and coating performance make it replace electroless copper plating in many occasions. Especially in the conductivity and decoration of the coating, it is better than electroless copper plating.
