Dimensionally-controlled cobalt-containing precision molded metal article |
摘要 |
The shrinkage normally encountered when molding a mixture of spherical cobalt-containing particles and thermoplastic binder, heating the resulting molded article to degrade the binder and form a porous preform, and infiltrating the same is counteracted by adding finely divided elemental iron or elemental nickel to the spherical cobalt-containing particles. In addition to improving dimensional control, the elemental powder addition increases impact strength while maintaining hardness.
