1. A method for applying an abrasive, the method comprising: applying, to a substrate, the integral combination of: a self-braze material;an abrasive;a matrix in which the abrasive is at least partially embedded; andan intermediate layer between the self-braze material and the matrix; andheating to
1. A method for applying an abrasive, the method comprising: applying, to a substrate, the integral combination of: a self-braze material;an abrasive;a matrix in which the abrasive is at least partially embedded; andan intermediate layer between the self-braze material and the matrix; andheating to cause the self-braze material to braze to the substrate. 2. The method of claim 1 wherein the intermediate layer is a cast layer. 3. The method of claim 1 wherein the heating leaves at least a portion of the self-braze material with a composition comprising, in weight percent: cobalt 2.5-13.5;chromium 12-27;aluminum 5-7;yttrium 0.0-1.0;hafnium 0.0-1.0;silicon 1.0-3.0;tantalum 0.0-4.5;tungsten 0.0-6.5;rhenium 0.0-2.0;molybdenum 0.1-1.0; andthe balance nickel. 4. The method of claim 3 wherein: said portion of the self-braze material has said composition comprising, in weight percent: cobalt 2.5-13.5;chromium 12-27;aluminum 5-7;yttrium 0.0-1.0;hafnium 0.0-1.0;silicon 1.0-3.0;tantalum 2.0-4.5;tungsten 2.0-6.5;rhenium 0.0-2.0;molybdenum 0.1-1.0; andthe balance nickel. 5. The method of claim 3 wherein: said composition has no more than 1.0 weight percent of any other individual element. 6. The method of claim 3 wherein: said composition has no more than 3.0 weight percent of all other individual elements combined. 7. The method of claim 1 wherein: the matrix comprises an MCrAlY; andthe abrasive comprises cubic boron nitride. 8. The method of claim 3 wherein the self-braze material comprises a sintered sheet of: at least one first alloy of low melting point relative to the melting point of the substrate; andat least one second alloy of high melting point relative to the melting point of the first alloy. 9. The method of claim 8 wherein: the at least one first alloy comprises about 21.25-22.75 chromium, about 5.7-6.3 aluminum, about 11.5-12.5 cobalt, about 5.7-6.3 silicon, boron in an amount no greater than 1.0 weight percent, and a balance of nickel plus impurities if any; andthe at least one second alloy comprises about 4.75-10.5 chromium, about 5.5-6.7 aluminum, up to about 13 weight percent cobalt, about 3.75-9.0 tantalum, about 1.3-2.25 molybdenum, about 3.0-6.8 tungsten, about 2.6-3.25 rhenium, up to about 0.02 boron, about 0.05-2.0 hafnium, up to about 0.14 carbon, up to about 0.35 zirconium, and a balance of nickel plus impurities if any. 10. The method of claim 9 wherein: a boron content of the first alloy is at least 0.30 weight percent greater than a boron content, if any, of the second alloy. 11. The method of claim 9 wherein: the at least one first alloy comprises no more than 1.0 weight percent of any other individual element; andthe at least one second alloy comprises no more than 1.0 weight percent of any other individual element. 12. The method of claim 1 wherein: the matrix has a characteristic thickness T2 of 0.10-0.50 millimeters;the intermediate layer has a thickness of T3 of 0.50-2.50 millimeters; andthe self-braze material has a characteristic thickness T1 of 0.20-2.5 millimeters. 13. The method of claim 1 wherein: the applied combination consists of the self-braze material, the intermediate layer, the abrasive, and the matrix. 14. The method of claim 1 further comprising forming the combination by: slurry plating the abrasive and one or more components of the matrix to a first face of a sheet of material of the intermediate layer;securing said sheet to a sheet of self-braze material; andcutting the combination of the plated sheet of intermediate layer material and sheet of self-braze material. 15. The method of claim 14 further comprising forming the sheet of self-braze material by: mixing powders of at least two different alloys; andsintering the mixture. 16. The method of claim 14 wherein: the slurry plating comprises nickel and/or cobalt entrapment plating of CrAlY particulate; andnickel and/or cobalt entrapment plating of the abrasive. 17. The method of claim 1 wherein: the heating leaves forms from the self-braze material a base layer bonding the intermediate layer to the substrate leaving the abrasive at least partially embedded in the matrix. 18. The method of claim 17 wherein: at least a portion of the base layer has a composition comprising, in weight percent: cobalt 2.5-13.5;chromium 12-27;aluminum 5-7;yttrium 0.0-1.0;hafnium 0.0-1.0;silicon 1.0-3.0;tantalum 0.0-4.5;tungsten 0.0-6.5;rhenium 0.0-2.0;molybdenum 0.1-1.0; andthe balance nickel plus impurities, if any. 19. The method of claim 17 wherein the substrate is a substrate of a turbine blade and wherein the base layer is along a tip surface of an airfoil of the blade.
