Aspects of electroless nickel plating on molybdenum
Conference
·
OSTI ID:6944369
A process for depositing an adherent coating of an electroless nickel-phosphorus alloy on molybdenum was developed. The required pretreatment processes included an anodic etch in a chromic acid-nitric acid solution, an anodic etch in a phosphonic acid solution, and an oxide stripping step in a chromic acid-nitric acid solution. Initiation of the electroless nickel plating was accomplished through a series of strikes in the nickel bath. Scale up from laboratory parts to large components involved optimization of parameters such as pretreat time, current density, anode to cathode ratio and strike time.
