Griekspoor Thermal Coatings has recently developed TOPCOAT® 107: a nickel based super alloy blended with carbides. TOPCOAT® 107 is developed as an improved and very economical hard chrome and nickel/chromium replacement.

TOPCOAT® 107 combines the hardness of the carbides with the flexibility, tenaciousness, and toughness of the super alloy. This combination results in excellent corrosion resistance together with outstanding wear resistance against fretting, abrasion, and cavitation.

Typical applications:

  1. Hard chrome or nickel/chromium replacement for hydraulic piston rods. Especially long thin rods with a lot of flex can be coated reliably with no risk of cracking during use;
  2. Mandrels;
  3. Very accurate rollers in the film and paper industry;
  4. Coating and/or repair of bearing and sliding surfaces.
