The general aim of this study is to develop the surface functionalization process in metal powder injection molding (MIM). A gas nitriding process which can improve the wear and corrosion resistances was investigated for sintered Ti and its alloy parts through the MIM process to realize the high functionality at low processing cost. The effects of the specimen size and the process conditions on the nitriding reaction in the Ti-6Al-4V MIM parts were mainly investigated by micro-structural observation and hardness measurements. The gas nitriding mechanisms were discussed. The results suggested that the gas nitriding process was a useful surface treatment process for high functionality of micro metal injection molding (μ-MIM) products.
