抄録

Metal injection molding (MIM) process is hoped to be quite useful for improvement of the quality and productivity in the automotive sintered parts. In our previous studies, high performance ferrous sliding abrasive wear-resistant materials using prealloyed steel (SCM440) and 3mass%TiN powders were obtained by MIM process.<BR>This study has been investigated to develop the high performance self-lubricating wear-resistant materials in the same way. A water atomized tool steel (SKD11) powder was used as the matrix and 2-8mass% CaF₂ powder was added to improve the self-lubricating properties. The compacts were densified to near full density by liquid phase sintering at 1493K, and the final carbon content was controlled to be almost 1.6mass%. CaF₂ powder particles were distributed uniformly in the compacts. Addition of 6mass% CaF₂ powder caused a remarkable improvement of wear-resistance under non-lubricating conditions. This indicates that MIM process has enormous potential to produce high performance ferrous composites for the automotive sintered parts.
