Abstract
Powder injection molding can be used to fabricate bi-material components that provide unique functionality such as a combination of toughness and wear resistance. Successful processing of these components requires minimization of internal stresses during sintering. In this article, the stresses generated during co-sintering of concentric rings are analyzed, compared to the materials’ strengths, and correlated with defects. The results provide guidelines for determining the compatibility of various materials and the effect of component geometry.
