Properties of Electroless Nickel - Phosphorus PPF Deposits after Crystallization
t is well recognized that electroless I.' nickel-phosphorus offers excellent deposition characteristics, such as uniform coverage, freedom from porosity, hardness, corrosion resistance, solderability, braze and weldability, wear resistance and lubricity.' Interest in the properties of electroless nickel has grown in recent years, leading to the development of wide-ranging applications, a compre...
متن کاملTHE STUDY OF ELECTROLESS COATING OF NICKEL ON CARBON FIBERS
The continuity and thickness of the coating layer, are the most important factors in wetting properties and strength of carbon fibers. These factors are crucial in the quality of metal matrix composites made with carbon fibers. In this research the Polyacrylonitrail base carbon fibers have been nickel coated with 0.2, 0.5, 0.8 and 11 ,u in thickness, by the electroless method. The effect of the...
متن کاملCopper electroless plating in weakly alkaline electrolytes using DMAB as a reducing agent for metallization on polymer films
Copper electroless plating at low pH (7–9) using dimethylamine borane complex as a reducing agent is studied electrochemically by linear sweep voltammetry, cyclic voltammetry and chronopotentiometry in full electrolytes. We find that the mixed potential theory is not applicable to the described system. We show that both the working potential and the rate-controlling mechanism are dependent on t...
متن کاملElectroless Nickel Plating on Magnesium Alloy
he inherent lightness and good strength-to-weight ratio of T magnesium has focused attention on increasing applications in aerospace and allied fields. Its density is two thirds that of aluminum-a conventional structure material for aerospace. Magnesium has one drawback: It is prone to atmospheric corrosion. Further, because of its high chemical affinity for aqueous solutions, it is categorized...
متن کاملOptimizing Electroless Nickel Pretreatment Processes
The pretreatment of the substrate, prior to Electroless Nickel (EN) plating, plays an important role in the corrosion protection provided by the EN deposit. Many factors in the pretreatment process can affect the corrosion resistance of the EN deposit. The details of mechanical treatment, chemical/elecuo polishing, acid activation, and pre-processing procedure (such as nickel strike) are among ...
