What is the best substrate for coating?
While FortiPhy coatings can improve the toughness of nearly any metal, critical applications call for better materials. High-performance tool steels or carbides, with a fine surface finish, are the best choice for extreme applications. In addition, the ideal material would have a final tempering temperature higher than 975ºF to prevent annealing during the coating process. The ultimate hardness and toughness of FortiPhy coatings are related to the hardness of the substrate.
