CORROSION PROTECTION WITH NICKEL‐BASE HARDSURFACING ALLOYS

Hardsurfacing with Ni/Cr‐base alloys gives additional advantages in protection against corrosion and atmospheric and high‐temperature oxidation. The latter effects frequently contribute greatly to the rate of wear. The self‐fluxing characteristics of such boron‐containing alloys, coupled with a wide melting range, enables the coating of contoured surfaces and application by spraying and fusing. Using a bonding agent very thin protective coatings may be applied by furnace fusion.
