Abstract: A method (300) of making a pre-sintered preform (160), including forming a pre-sintered preform (160) by a binder jet additive manufacturing technique. The binder jet additive manufacturing technique includes depositing a first powder layer (110) including a first powder and a second powder followed by depositing a first binder at a pre-determined location of the first powder layer (110). The binder jet additive manufacturing technique also includes depositing a second powder layer (130) over at least a portion of the first powder layer (110) followed by depositing a second binder at a pre-determined location of the second powder layer (130). At least a portion of the first binder and at least a portion of the second binder is cured forming a green part (150). The green part (150) is then densified to form a pre-sintered preform (160) near net shape component.

Abstract: A compound for metal powder injection molding includes secondary particles in which first metal particles are bound to one another, and a matrix region including a binder and second metal particles whose constituent material is different from that of the first metal particles. It is preferred that in the secondary particles, the first metal particles are bound to one another through the binder. It is also preferred that the average particle diameter of the second metal particles is smaller than that of the first metal particles.

Abstract: There is provided a sliding part in which a surface coverage ratio of copper in the sliding part increases. A bearing which is the sliding part is formed by filling the raw powder into the filling portion of the forming mold, compacting the raw powder to form a powder compact 6, and sintering the powder compact 6. A copper-based raw powder is composed of a copper-based flat raw powder 2 having an average diameter smaller than that of an iron-based raw powder 1 and an aspect ratio larger than that of the iron-based raw powder 1, and a copper-based small-sized raw powder 3 having the average diameter is smaller than that of the copper-based flat raw powder 2. The copper is allowed to segregate at the surface of the sliding part. In the bearing in which the copper-based flat powder 2 segregates at the surface, the surface is covered with the copper-based small-sized raw powder 3 that has emerged on the surface, as well as the copper-based flat raw powder 2, thereby it is possible to increase the surface coverage ratio of copper. Furthermore, containing calcium fluoride improves the seizure resistance.
