摘要： A method for preparing a carbide protective layer comprises: (A) mixing a carbide powder, an organic binder, an organic solvent and a sintering aid to form a slurry; (B) spraying the slurry on a surface of a graphite component to form a composite component; (C) subjecting the composite component to a cold isostatic pressing densification process; (D) subjecting the composite component to a constant temperature heat treatment; (E) repeating steps (B)-(D) until a coating is formed on a surface of the composite component; (F) subjecting the coating to a segmented sintering process; (G) obtaining a carbide protective layer used for the surface of the composite component. Accordingly, while the carbide protective layer can be completed by using the wet cold isostatic pressing densification process and the cyclic multiple superimposition method, so that it can improve the corrosion resistance in the silicon carbide crystal growth process environment.

摘要： A multicomponent carbide has at least five transition metals, and a valence electron concentration (VEC) is greater 8.80 electrons. Preferred off-equiatomic multicomponent carbides have five transition metals and a VEC of more than 8.80. Preferred equiatomic multicomponent carbides have five transition metals and a VEC of 9.00 or greater. The valence electron configuration is important for its relationship to the mechanical properties of carbides. Since carbon forms four bonds, when there are more than four valence electrons available from the metals, there are excess electrons in the system. This increases metallic character of bonding and therefore allows for more ductility and higher toughness.

摘要： Polycrystalline compacts include a polycrystalline superabrasive material comprising a first plurality of grains of superabrasive material having a first average grain size and a second plurality of grains of superabrasive material having a second average grain size smaller than the first average grain size. The first plurality of grains is dispersed within a substantially continuous matrix of the second plurality of grains. Earth-boring tools may include a body and at least one polycrystalline compact attached thereto. Methods of forming polycrystalline compacts may include coating relatively larger grains of superabrasive material with relatively smaller grains of superabrasive material, forming a green structure comprising the coated grains, and sintering the green structure. Other methods include mixing diamond grains with a catalyst and subjecting the mixture to a pressure greater than about five gigapascals (5.0 GPa) and a temperature greater than about 1,300° C. to form a polycrystalline diamond compact.

摘要： A cemented tungsten carbide body is formed by mixing a tungsten carbide powder and a cobalt powder together to form a powder mixture. The tungsten carbide powder makes up greater than or equal to 80 weight percent of the powder mixture, while the cobalt binder powder makes up about 1.5 weight percent to about 20 weight percent of the powder mixture. Next, the powder mixture is compacted to form a green compact, and a boron nitride coating is applied to a surface of the green compact to form a coated compact. The coated compact is sintered at a temperature sufficient to melt the cobalt powder, such that boron from the boron nitride coating diffuses into the compact and creates a gradient of metallic cobalt and boron extending inward from the surface. The metallic cobalt content increases from the surface inward, while the boron content decreases from the surface inward.
