    摘要: An insulating liner for use with exhaust system or pollution control devices such as catalytic converters and diesel particulate filters or traps. The insulating liner is shown in relation to an end cone for use with a catalytic converter. The end cone includes an outer metallic end cone and a free-standing insulating cone positioned within the outer metallic end cone. A substantial portion of the inner surface of the insulating liner is exposed to hot exhaust gas from an internal combustion engine. The insulating liner is preferably formed of a composite containing inorganic fibers and/or particles, which makes the insulating liner rigid, yet capable of withstanding repeated mechanical and thermal shocks.

    摘要: A molded, non-refractory metal article is made by molding in a flexible mold a plastic mixture of non-refractory, spherical metal powders and a heat-fugitive binder comprising thermoplastic material to form a green article of predetermined shape and dimensions, heating the green article to remove said binder and consolidate the non-refractory spherical powders in the form of a porous, monolithic skeleton of necked particles of non-refractory metal, infiltrating the skeleton with a molten metal having a melting point that is at least 25.degree. C. less than the melting point of the lowest melting of said spherical, non-refractory metal particles, and cooling the infiltrated skeleton thereby forming a homogeneous, void-free, non-refractory metal article of two intermeshed metal matrices.

    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.
