  • Patent number: 9376573
    Abstract: A heterogeneous composite body that is spall resistant and comprises a substantially discontinuous cermet phase in a substantially continuous metal rich matrix phase. The heterogeneous composite body is typically bonded to a substrate to form a hardfacing on the substrate. The heterogeneous composite body exhibits ductile phase toughening with a strain to failure of at least about 2 percent, a modulus of elasticity of less than about 35 million pounds per square inch, and a density of less than about 7 grams per cubic centimeter. The metal rich matrix phase between the ceramic rich regions in the heterogeneous composite body has an average minimum span of about 0.5 to 8 microns to allow ductility in the heterogeneous composite body. The heterogeneous composite body has a Vicker's hardness number of greater than approximately 500. The ceramic rich regions exhibit high hardness as compared with the matrix phase.

  • Patent number: 9011926
    Abstract: In a production process of granules containing a biologically active substance, variation in the elution profile of the biologically active substance is reduced by heating the temperature of granules to about 50° C. or higher and maintaining the temperature for about 1 minute or longer. By setting the spray speed to about 90 mg/min or more per 1 g of cores when a spray agent for a primary agent containing the biologically active substance is sprayed while spraying a binding liquid to the cores and setting the total feeding weight per unit area for a centrifugal fluidized bed coating granulation machine to about 1.5 g/cm2 or more, the variation in the elution profile of the biologically active substance from the granules is reduced.
