Abstract
Various nozzles, components of nozzles, and methods, materials and devices for making them are disclosed.
Claims20
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.

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, and
- wherein material to be sprayed travels from said bore, through said sintered polycrystalline diamond compact nozzle tip and out said exit orifice.

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;
- and
- wherein at least some of said bonds are sp3 carbon bonds.
