Development of High Performance Ti Products by Micro Metal Injection Molding

JSME Materials and Processing /2005 巻 (2005)

Abstract: 
Micro metal injection molding (μ-MIM) is hoped to be one of manufacturing process for minute parts in various engineering fields.  In order to improve the quality of μ-MIM products, several techniques have been developed in the process so far.  The properties of final products were strongly influenced by the debinding and sintering conditions.  Also the size of μ-MIM products is too so small to that change the properties maybe easily changedby surface treatment such as nitriding.  The aim of this study is to produce high performance titanium micro parts by μ-MIM.  It was suggested that the microstructure and nitrogen content of μ-MIM compacts are considered to be strongly and easily influenced by nitriding treatment, which may lead the higher performance of μ-MIM compacts.
