ABSTRACT:
The invention is a high-strength, pre-coated, titanium or titanium-alloy material component comprising a titanium or titanium-alloy material article having ultra-fine, submicron grain size microstructure and an organic coating of phenolic resin applied to the surface of the article. The article is prepared from a coarse grain titanium or titanium-alloy powder material that is cryomilled into an ultra-fine, submicron grain material, degassed, and densified. The densified material is formed or otherwise processed into a article, and pre-coated with an organic coating containing phenolic resin prior to installation or assembly.
