Nickel Chromium Alloy Electrodeposition: Surprising Success

Summary for nickel chromium alloy electrodeposition Discussion

Nickel-chromium alloy electrodeposition is presented as a difficult problem, especially for a coating with less than 8 wt% chromium. In response to Mohamad Saqib Ayub’s question, Ted Mooney says the classic reference by Brenner does not really acknowledge nickel-chromium alloys and notes that only sketchy reports existed, with even well-known researchers unable to reproduce them. He adds that Safranek’s book points to a 1985 AES conference presentation by Lashmore, Wisehauss, and Pratt, which reported success using pulse plating. However, Mooney also recalls David Lashmore later suggesting the result may not have been a true alloy at all, but a multilayer “sandwich” of alternating nickel and chromium microlayers. The thread therefore suggests that practical nickel-chromium deposition is uncertain and that the reported success may depend on pulse plating or layered deposition rather than a straightforward alloy bath.
