A method of producing a mechanical face seal, the method including a step of obtaining a cast or wrought substrate part having an inner diameter, outer diameter, and a planar surface. The method may include a rough surface treatment step to form pores, peaks, and valleys on the planar surface of the substrate part. The method may further include a spraying step to supply a spray coating material onto the substrate part to form a protective thermal spray coating layer on the substrate part.
