Strongly adherent Pt coating was deposited on Ti alloy substrates using double glow plasma technology. The polycrystalline Pt coating exhibited a preferred (220) orientation. The coating strongly adhered to the substrate, and the adhesive forces between the coating and substrate were all greater than 60 N. The hardness and elastic modulus of the coating were about 1.2 and 180 GPa, respectively. Adherent Pt coating had a better corrosion resistance than the bare substrate in terms of polarization curves. The bright Pt coating was still well bonded to the substrate after corrosion testing. This work suggested that strongly adherent Pt coatings on Ti alloy substrates can be used in industrial production processes. (C) Koninklijke Brill NV, Leiden, 2012
