ChemInform Abstract: Effect of Molybdenum Codeposition on the Thermal Properties of Electroless Ni-B Alloy Plating Films.
Abstract
Ni-Mo-B alloy films of 2 μm thickness are deposited electroless on α-Al2O3 ceramics from a caustic alkaline bath using Me2NH·BH3 as the reducing agent (pH 9, 90 °C).
ChemInform Abstract
Ni-Mo-B alloy films of 2 μm thickness are deposited electroless on α-Al2O3 ceramics from a caustic alkaline bath using Me2NH·BH3 as the reducing agent (pH 9, 90 °C). Both crystalline and amorphous alloys films containing more than 20 wt% Mo and a small amount of B are prepared by controlling the Mo-complex concentration of the bath. The maximum resistivity under as-plated conditions is 322 μΩcm and increases after heat treatment at 500 or 600 °C to 347 μΩcm. TEM observations of these thermally stable high resistivity films show a mosaic-like structure.
