Griekspoor has developed a material that is similar to Inconel 625 but has higher corrosion resistance and higher chemical resistance. It is marketed as “TOPCOAT® 177”and can be used as a single layer laserclad 625 alternative. TOPCOAT® 177 is also used as base coating in all coatings with ‘+’ at the end, where it gives higher corrosion resistance than the standard nickel base coating.
In TOPCOAT® 107 the Inconel-like material is used as a matrix with carbides mixed in. The matrix provides high corrosion resistance and chemical resistance with the carbides adding wear resistance.
