Nickel plated - multi-layer nickel plating

August 30, 2023

Multi-layer nickel plating is to obtain two or three layers of nickel plating on the same substrate with different plating solution components and process conditions. The purpose is to increase the thickness of the nickel layer without increasing the thickness of the nickel layer or reducing the nickel layer. corrosion resistance. The multi-layer nickel/chromium combined layer systems currently used in production include:


Double nickel        Semi-bright nickel/bright nickel/chromium

Triple nickel           Semi-bright Nickel/high sulfur nickel/bright nickel/chromium

                              Semi-bright nickel/bright nickel/nickel seal/chrome (microporous chrome)

                              Semi-bright nickel/bright nickel/high stress nickel/chromium (microcracked chromium)
