대표청구항▼
1. A spray nozzle comprising:a nozzle body,a nozzle entry orifice through which a material to be sprayed can enter,a nozzle bore through which a material to be sprayed can pass,a nozzle exit orifice through which a material to be sprayed can exit,a sintered polycrystalline diamond compact bore liner
1. A spray nozzle comprising:a nozzle body,a nozzle entry orifice through which a material to be sprayed can enter,a nozzle bore through which a material to be sprayed can pass,a nozzle exit orifice through which a material to be sprayed can exit,a sintered polycrystalline diamond compact bore liner in said bore for providing low wear, durable and long-lasting service in the nozzle,interstitial spaces in said diamond compact,solvent-catalyst metal located in said interstitial spaces,a zone in said diamond compact that includes both sintered diamond and solvent-catalyst metal, said zone having a composition gradient of solvent catalyst metal content to diamond content, said zone further having a first side and a second side, the ratio of diamond to solvent catalyst metal being higher at said first side than at said second side,chemical bonds in the sintered polycyrstalline diamond compact bore liner, said chemical bonds including diamond-to-diamond bonds, diamond-to-metal bonds, and metal-to-metal bonds. 2. A spray nozzle as recited in claim 1 wherein said diamond compact is free standing diamond that is not sintered to a substrate. 3. A spray nozzle as recited in claim 1 wherein said diamond compact comprises diamond feedstock that has diamond particles that have a dimension in the range of less than about 1 nanometer to more than about 100 microns. 4. A spray nozzle as recited in claim 1 wherein said solvent-catalyst metal includes CoCr. 5. A spray nozzle as recited in claim 1 wherein at least some of said bonds are sp3 carbon bonds. 6. A spray nozzle as recited in claim 1 wherein said diamond compact includes a substrate. 7. A spray nozzle comprising:a nozzle body,a nozzle entry orifice through which a material to be sprayed can enter,a nozzle bore through which a material to be sprayed can pass,a nozzle exit orifice through which a material to be sprayed can exit,a sintered polycrystalline diamond compact nozzle tip at said exit orifice,interstitial spaces in said diamond compact,solvent-catalyst metal located in said interstitial spaces,chemical bonds in the sintered polycyrstalline diamond compact nozzle tip, said chemical bonds including diamond-to-diamond bonds, diamond-to-metal bonds, and metal-to-metal bonds, andwherein material to be sprayed travels from said bore, through said sintered polycrystalline diamond compact nozzle tip and out said exit orifice. 8. A spray nozzle as recited in claim 7 wherein said diamond compact is constructed from diamond feedstock that has diamond particles with a dimension in the range of less than about 1 nanometer to more than about 100 microns. 9. A spray nozzle as recited in claim 7 wherein said solvent-catalyst metal is CoCr. 10. A spray nozzle as recited in claim 7 wherein at least some of said bonds are sp3 carbon bonds. 11. A spray nozzle as recited in claim 7 wherein said diamond compact includes a substrate to which said diamond is sintered. 12. A spray nozzle as recited in claim 7 wherein said diamond compact is free standing diamond that is not sintered to a substrate. 13. A spray nozzle as recited in claim 11 further comprising a residual stress field that tends to enhance the strength of attachment of said diamond to said substrate. 14. A spray nozzle as recited in claim 13 wherein said residual stress field is caused by dilitation of said substrate. 15. A spray nozzle as recited in claim 14 wherein said diamond and said substrate have coefficients of thermal expansion that are not identical. 16. A spray nozzle as recited in claim 15 wherein said diamond and said substrate have moduluses that are not identical. 17. A spray nozzle as recited in claim 16 further comprising a mechanical grip between said diamond and said substrate. 18. A spray nozzle as reicted in claim 17 further comprising substrate surface topographical features. 19. A spray nozzle as recited in claim 17 further comprising an interface between said diamond and said substrate, said interface being non-plan ar. 20. A spray nozzle comprising:a nozzle body,a nozzle entry orifice through which a material to be sprayed can enter,a nozzle bore through which a material to be sprayed can pass,a nozzle exit orifice through which a material to be sprayed can exit,a sintered polycrystalline diamond compact liner at said exit orifice,said sintered polycrystalline diamond compact being constructed of sintered polycrystalline diamond constructed by a high pressure and high temperature sintering process that creates diamond to diamond bonds in said diamond compact,interstitial spaces in said diamond compact,solvent-catalyst metal located in said interstitial spaces,chemical bonds in the sintered polycyrstalline diamond compact nozzle tip, said chemical bonds including diamond-to-diamond bonds, diamond-to-metal bonds, and metal-to-metal bonds,wherein material to be sprayed travels from said bore, through said sintered polycrystalline diamond compact nozzle tip and out said exit orifice; andwherein at least some of said bonds are sp3 carbon bonds.
