Function of Nickel Plating

Function of Nickel Plating

  1. Increases the homogeneity and reliability of bonding
  2. Prevents carbon migration from the backing steel, which prevents,
    1. High hardness at the boundary because of Martensite formation
    2. Cracks at the boundary
  3. Reduces the risk of cracking under hydrogen service and maintains the soundness of the clad layer
  4. Reduces the penetration rate of pitting and/or SCC, if initiated at the cladding surface thus givingan additional safety margin.
