Guilinger, T R

This patent describes a method of forming amorphous ternary nickel-phosphorus-chromium alloy deposits by electrodeposition on an electrically conductive substrate. It comprises: subjecting the substrate to an applied current density between about 20 and 40 A/dm{sup 2} at a temperature from the range of about 20{degrees} to 30{degrees}C in a bath. The bath comprising: a chromium salt and a nickel salt in a weight ratio of about 3:1, a phosphorus source at about 0.3 MP concentration; about 0.3 M of a complexing agent; about 0.1 M of a supporting salt; and about 1.0 M of buffer.
