Electroless nickel-boron-phosphorus deposits, the conditions of formation and features of structure

The deposition kinetics and the effect of various process parameters on the solution stability and the composition of electroless Ni-B-P deposits (pro duced with the simultaneous use of two reductants, i.e. hypophosphite and b orane or dimethylamine borane) were studied. The features of the original a lloy structure, as well as its phase transformations during the heating of the deposits, are revealed. The bath's stability and the deposition rate (1 0 mu m/h) are shown to be sufficiently high while the improved morphologic characteristics and enhanced thermal stability can be inherent in the origi nal structure of the deposits.
