The invention discloses a coated substrate product comprised of a titanium of titanium alloy substrate, at least one thin interlayer composed of a non-reactive noble metal and a hard outer coating selected from the group comprised of a ceramic, a hard metal, a hard metal compound and a diamond-like carbon, wherein at least the non-reactive noble metal interlayer which is immediately adjacent to the titanium or titanium alloy substrate is deposited onto the substrate by means of an electroless plating procedure, and the hard outer coating is deposited onto the non-reactive interlayer(s) by means of known chemical and physical vapor deposition techniques. The invention also discloses a method for making these coated substrate products.

A coated substrate product comprised of (1) a substrate selected from the group consisting of titanium and titanium alloy, which substrate has been treated with a mild abrasive to remove oxides from its surface, (2) a thin, non-reactive noble metal interlayer deposited by an electroless plating technique after the treatment with said mild abrasive, said noble metal coated substrate is then subjected to a heat treatment by heating the substrate and the noble metal interlayer to a temperature in the range of about 200°to about 300°C. in the presence of air or a temperature in the range of about 200°to about 475°C. in the presence of an inert gas selected from the group consisting of argon, helium and mixtures thereof, and (3) a hard outer coating selected from the group consisting of a ceramic, a hard metal, a hard metal compound and a carbon having a hardness of greater than 1,000 Vickers.
