OF ELECTROLESS NICKEL The mechanical properties of electroless nickel plated in acidic solutions as a function of phosphorus content are listed in Table 4.1 (14). These properties weredetermined with a tensile-testing device described by Kim and Weil(l5). It is evident that electroless nickel is a relatively strong but brittle material. The low

Electroless nickel is particularly suitable for components with complex geometries since this process allows the use of contour-accurate and uniform layers. Phosphorous deposition rates in the range of 6 – 12% result in layers with different properties. Schlötter offers a wide range of high-phos, medium-phos and low-phos processes (NiP).

Electroless coating (also known as autocatalytic coating) is defined as the deposition of a metallic coating by a controlled chemical reduction that is catalyzed by the metal or alloy being deposited. The electroless process has several advantages over electroplating: virtually unlimited throwing power. little or no excess deposit at high points.

Electroless nickel –phosphorus (Ni–P) deposits are produced from the electrochemical reduction of a nickel ion through the autocatalytic plating processes in the plating solution. The electroless plating process that led to the practical application of these deposits was first developed by Brenner and Riddell, and the first patent for it was awarded in 1950.

Add the sodium borohydride solution slowly. The amount of borohydride to remove 1 gram of nickel is theoretically 1.1 grams. However the borohydride reacts with other metals and some organics thus requiring about two times the expected amount. The sodium borohydride is added as a 12% solution in 43% sodium hydroxide.
