We claim: 1. A coated article comprising a substrate having a composite layer formed thereon, wherein said composite layer comprises an outer surface having a texture comprising a periodic distribution of protrusions, wherein each of said protrusions is between 0.01 micrometer and 50 micrometers, wherein said composite layer comprises a base phase and an infiltrate phase, said base phase contacting said substrate and comprising at least one of the group consisting of silicon, nitrides, steel, carbonitrides, borides, sulphides, chalcogenides, oxides, and silicides, and said infiltrate phase comprising at least one of the group consisting of diamond, silicon, nitrides, carbides, steel, carbonitrides, borides, sulphides, chalcogenides, oxides, and suicides. 2. The coated article of claim 1, wherein the base phase comprises a nitride and the infiltrate phase comprises a nitride different than the nitride of the base phase. 3. The coated article of claim 2, wherein the base phase comprises cubic boron nitride. 4. The coated article of claim 1, wherein the base phase comprises cubic boron nitride, and the infiltrate phase comprises at least one nitride of the group consisting of titanium nitride, titanium carbonitride, and titanium aluminum nitride. 5. The coated article of claim 1, wherein said outer surface of the composite layer has deposited thereon an overlay comprising at least one of the group consisting of nitrides, carbides, steel, carbonitrides, borides, sulphides, chalcogenides, oxides, silicides, polytetrafluoroethylene, and any combination thereof, wherein at least the endmost region of each protrusion is free of said overlay. 6. The coated article of claim 1, wherein the coated article is a tool comprising a work surface, and wherein the work surface is the substrate. 7. The coated article of claim 6, wherein said base phase comprises a nitride and said infiltrate phase comprises a nitride different than the nitride of the base phase. 8. The coated article of claim 7, wherein the base phase comprises cubic boron nitride. 9. The coated article of claim 7, wherein the base phase comprises cubic boron nitride, and the infiltrate phase comprises titanium nitride, titanium carbonitride, and titanium aluminum nitride. 10. The coated article of claim 7, wherein said outer surface has deposited thereon an overlay comprising at least one of the group consisting of nitrides, carbides, steel, carbonitrides, borides, sulphides, chalcogenides, oxides, suicides, polytetrafluoroethylene, and any combination thereof, wherein at least the endmost region of each protrusion is free of said overlay. 11. The coated article of claim 10, wherein said outer surface has deposited thereon an overlay comprising at least one of the group consisting of MoS2, ZnO, polytetrafluoroethylene (PTFE), a combination of MoS2+ZnO, a combination of PTFE+MoS2, and a combination of PTFE+ZnO2A1S2, and any combination thereof, wherein at least the endmost region of each protrusion is free of said overlay. 12. The coated article of claim 11, wherein said tool is a metal machining tool. 13. A coated article comprising a substrate and a coating, said coating comprising individually-over-coated particles, the individually-over-coated particles having an average particle size of less than 1 micron and the individually-over-coated particles comprising base particles coated with supplement particles, wherein said base particles comprise at least one of the group consisting of nitrides, carbides, steel, carbonitrides, borides, sulphides, chalcogenides, oxides, and suicides, and wherein said supplement particles comprise at least one of the group consisting of nitrides, carbides, steel, carbonitrides, borides, sulphides, chalcogenides, oxides, and silicides. 14. The coated article of claim 13, wherein said article is a particle. 15. The coated article of claim 13, wherein said coating comprising individually-over-coated particles has a textured outer surface. 16. The coated article of claim 13, wherein said article is a tool, and wherein said base particles are ZnO and said supplement particles are MoS2. 17. The coated article of claim 13, wherein the base particles are coated with a continuous layer of supplement particles. 18. The coated article of claim 13, wherein the base particles are coated with a discontinuous layer of supplement particles. 19. The coated article of claim 13, wherein the base particles are coated with multiple layers of supplement particles. 20. The coated article of claim 13, wherein the coating comprises more than one type of individually-over-coated particle. 21. A coated article comprising a substrate having a composite layer formed thereon, wherein said composite layer comprises an outer surface having a texture comprising a periodic distribution of protrusions, wherein each of said protrusions is between 0.01 micrometer and 50 micrometers, wherein said composite layer comprises a base phase and an infiltrate phase, said base phase contacting said substrate and comprising at least one of the group consisting of diamond, silicon, nitrides, carbides, steel, carbonitrides, borides, sulphides, chalcogenides, oxides, and suicides, and said infiltrate phase comprising at least one of the group consisting of, silicon, nitrides, steel, carbonitrides, borides, sulphides, chalcogenides, oxides, and suicides.
