摘要： A composite material can include: a substrate of a first reaction-bonded silicon carbide (first RB—SiC) material; and a reaction-bonded diamond-retaining silicon carbide (RB-DSiC) layer bonded to a surface of the substrate. In some aspects, the RB-DSiC layer includes diamond particles bonded with a second reaction-bonded silicon carbide (second RB—SiC) material. The diamond particles may be homogeneously distributed through the second RB—SiC or only at the surface thereof. The diamond particles can be in an ordered pattern or un-ordered pattern. For example, a CMP conditioning disc can include the composite material of one of the embodiments.

摘要： The method of curing reinforced concrete uses a liquid membrane-forming curing compound for the curing of reinforced concrete, but without fully coating the reinforced concrete with the curing compound, thus allowing for oxygen permeation through the reinforced concrete to effect passive layer formation on steel rebar embedded in the reinforced concrete. Prior to curing, a mask is applied to at least one surface of a slab of reinforced concrete, such that the mask covers about 10% of the surface area of the at least one surface. The at least one surface of the slab of reinforced concrete is then coated with a liquid membrane-forming curing compound. The liquid membrane-forming curing compound is allowed to dry, thus forming a curing compound layer on the at least one surface of the slab of reinforced concrete. The mask is then removed to form at least one uncoated region.

摘要： Methods of manufacturing a ceramic honeycomb body having a honeycomb structure with a matrix of intersecting walls, and a skin disposed on an outer peripheral portion of the matrix where the skin has a first average porosity and the interior portion of the matrix has a second average porosity that is greater than the first average porosity. The methods include coating at least the skin with a fluid formulation containing a sintering aid and subsequently firing the honeycomb structure. In certain embodiments, a glass layer is formed in the skin or in regions of the walls directly adjacent to the skin. In certain embodiments, the coating is applied to a green honeycomb structure, and in other embodiments the coating is applied to a ceramic honeycomb structure. Other honeycomb bodies and methods are described.

摘要： A method for manufacturing frying, grilling, baking, and/or cooking utensils involves creating a green body from powdery silicon carbide, carbon, fillers, binders, and additives using ceramic shaping methods such as pressing, isostatic pressing, hot pressing, casting, die casting, or injection molding. The green body is carbonized and subsequently infiltrated with a metallic silicon melt. Through a final infiltration firing, the green body, together with carbon, forms a silicon carbide bonding matrix, resulting in a dimensionally stable frying, grilling, baking, and/or cooking utensil of the highest stability without residual porosity and with a temperature resistance of up to 1,350° C. This method gives rise to the aforementioned cookware, produced through the described process.
