At least one of the mating wear surfaces of a sliding mechanical seal is coated with diamond. The coating includes an underlayer of high resistance to wear and an overlayer with a reduced resistance to wear as compared to that of the underlayer. The reduced wear resistance of the overlayer prevents damage by the diamond to the opposing mating surface during the wear-in period of use.
