Abstract
A seal has: a metallic substrate; and a coating layer, The coating layer has in atomic percent of all metals in the coating layer: 6.5 to 22.0 Al; 14.0 to 23.0 Fe; 14.0 to 23.0 Co; 14.0 to 23.0 Cr; 14.0 to 23.0 Mn; and 14.0 to 23.0 Ni. The coating may be applied by high velocity oxy-fuel (HVOF) spray.
