In this study, gas nitriding was processed for various sizes of Titanium parts which were produced by metal injection molding (MIM) process, for the sake of enabling the high functionality at low processing cost. It was shown from the experiments that nitriding treatment resulted in increasing hardness on the surface and the microstructure changed to the TiN and acicular α-Ti phase. To effect on the size of parts, micro dumbbell specimen had around five times higher content of nitrogen than block ones. It is concluded that the size of μ-MIM products is so small that surface treatment can contribute significantly to improve the properties, and then gas nitriding process is one of effective surface treatment methods for high functionality of μ-MIM products.
