Abstract
The microstructural evolutions and properties of the surface composite produced via the friction stir nitriding (FSN) method on Ti-6Al-4V alloy were investigated. Due to the optimized process parameters and suitable mixed gas proportion for a limited combustion reaction between Ti and N2, a composite layer with the thickness of ~200 m beneath an outermost thin TiN layer was fabricated. The composite layer was composed of three microstructure types. Formation mechanisms for microstructure evolutions during FSN on titanium alloy were detailed in terms of three steps.
