Electrodeposition of amorphous ternary nickel-chromium-phosphorus alloy
Patent
·
OSTI ID:5542260
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 comprising: a chromium salt and a nickel salt in a weight ratio of about 3:1, a phosphorus source of about 0.3 M P concentration; about 0.3 M of a complexing agent; about 0.1 M of a supporting salt; and about 0.1 M of buffer.
