1. Principle of electroless chemical deposition

The basic principle of electroless plating is relatively simple: metal salt(s) are dissolved and reduced by an appropriate chemical agent. Nickel is the metal most frequently deposited by this type of process, and several reducing agents can be used, giving rise to the generally accepted classification of electroless nickel deposits: pure nickel deposits, phosphorus deposits and boron deposits. .

The principle of chemical deposition may appear relatively straightforward compared with that of electrolytic deposition, with which it shares many common features, but also differences such as the possibility of coating non-conductive substrates, the absence of edge effects, adequate...
