Coating Steel with Nickel by Immersion in Nickel Chloride Solutions

Abstract: A simple method for depositing controlled amounts of nickel on steel by chemical displacement from a hot nickel chloride, boric acid solution is described. Deposits up to 30 millionths inch (0.75 micron) in thickness can be readily produced in this way. Suitable heat treatment of these deposits renders them compact and adherent and at the same time causes diffusion of the nickel and iron. Although steel coated in this way rusts readily, its surface is altered sufficiently to suggest that it will serve as a bet… Show more

“…Nickel can be deposited via conventional EL ( vide infra ) and galvanic ,,, methods, though in the latter case Ni more often functions as a sacrificial substrate for replacement by other metals than the deposited metal. ,,,,− Conventional EL Ni depositions utilize baths containing H 2 PO 2 – , amine boranes, , BH 4 – , or to a lesser extent, N 2 H 4 , as reducing agents. Baths containing H 2 PO 2 – deposit the metal as NiP alloys, whereas those containing amine boranes or BH 4 – yield NiB alloys and those containing N 2 H 4 deposit Ni metal.…”

“…However, it is the discovery of hypophosphite (H 2 PO 2 – ) as a reducing agent for Cu II and Ni II salts in the 19th century, together with the characterization of the reduction process and its extension to include other metal salts during the early 20th century, that have provided the background for growth of the field. The pivotal demonstration by Brenner and Rendell, who coined the term “electroless”, of EL Ni metal plating of steel , is largely responsible for igniting increased interest in practical applications of the EL process that mark the modern era for its widescale adoption and exploitation in industry.…”

“…Under favorable conditions it is possible to deposit an immersion coating of nickel on steel from a hot concentrated solution of nickel chloride of 0.00002-inch thickness in 10 minutes (17). Such deposits are very porous and must be heat treated to decrease porosity by lateral diffusion and to increase adhesion.…”

“…Since there were many recesses in the several pump parts, it was decided to produce the coating by electroless plating (1). This method is distinct from plating due to displacement by the metal on which the nickel is to be deposited, a procedure which was discussed by Piontelli (2) and, more recently, by Wesley and Copson (3).…”
