Electroless Nickel as a Functional Coating | Electroless …
The resulting nickel-phosphorus alloy possesses many unique and desirable characteristics making it a superior engineering material. By avoiding the problems associated with electrolytically applied coatings (ie high and low current densities with corresponding high and low plating thicknesses on the part or no plate in recesses), EN deposits in contrast, are of uniform thickness and hard.
Electroless Nickel Plating Ammonia - SUMS
Improved standard electroless nickel plating composition specific for making ohmic contacts to silicon and other semiconductor materials. ADVANTAGES Stable, ready to use Plates uniformly on p- and n- type silicon Offers excellent adhesion and solderability
The use of three different materials, 2-mercaptobenzimidazole, 2-mercaptobenzothiazole, and thioglycolic acid, was investigated to improve the performance of electroless nickel-plating baths. By changing the concentrations of these materials, sample plates were coated. Optical microscope images were obtained by selecting representative coated plates. From the results of the investigations, the
Several variations on the electro-less nickel plating process exist. One such variation is composite electroless nickel plating, which deposits silicon carbide along with a nickel alloy for even stronger resistance properties on the finished product.
Electroless nickel is a hard, silver coloured coating comprised of nickel alloyed with between 4 and 14% phosphorus. It is deposited by immersion of parts in a solution of nickel salts and reducing agents at a temperature of 90 C. Although it has the appearance of
Chromium Plating - an overview | ScienceDirect Topics
J.K. Dennis, T.E. Such, in Nickel and Chromium Plating (Third Edition), 1993Anodes Anodes of chromium metal would neither be economical to manufacture nor technically advisable for chromium plating baths, for they would dissolve at approximately 100% efficiency and hence rapidly increase the chromium content of the baths.
Nickel Silicon Carbide (CODIAC) Information
Nickel Silicon Carbide (CODIAC) is a regenerative layer of an electrolessly plated matrix, usually a nickel/phosphorus alloy, with finely divided particles uniformly dispersed in it. The particles are uniform in size and the coating contains 30% carbide by volume. The
