Paper Title:
Micro Metal Injection Molding Process for High Performance Titanium Alloy
  Abstract

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