| The abrasive resistance of marine titanium and its alloys is relatively poor and they are likely to be corroded in seawater, and the precious metals-based surface modifiers are capable of improving the abrasive and corrosion resistance of marine titanium and its alloys. Based on the analysis of the property of titanium and its alloys, the present paper, as a review, summarized the role of precious metals Au and Ag in improving the abrasive resistance as well as the role of precious metals Pd, Ru, Ag, and Au in enhancing the corrosion resistance. And then, the surface modification technologies of precious metals including ion implantation, magnetron sputtering, and double glow plasma discharge alloying process were introduced. Finally, the development trend of composite modification and nano crystallization in modified layer was prospected. |
