Method of doping surfaces
Disclosed herein are methods of treating an article surface. The method comprises removing a metal oxide surface from the metal substrate to expose a metal surface; and delivering particles comprising a dopant from at least one fluid jet to the metal surface to impregnate the surface of the article with the dopant. The method also comprises delivering substantially simultaneously a first set of particles comprising a dopant and a second set of particles comprising an abrasive from at least one fluid jet to a surface of an article to impregnate the surface of the article with the dopant.
1. A method of treating a surface of an article, the method comprising:
delivering substantially simultaneously a first set of particles comprising a first material and a second set of particles comprising a second material different from the first material from at least one fluid jet to the surface of the article, wherein the first and second sets of particles have a weight ratio of first material to second material ranging from 80:20 to 20:80;
removing a portion of the surface with the second set of particles to allow the first set of particles to impregnate the surface; and
impregnating the surface with the first set of particles.
2. The method of claim 1 , wherein the first material comprises a combination of at least two different compounds.
3. The method of claim 1 , wherein the first material comprises at least one compound chosen from calcium phosphate, calcium carbonate, barium titanate, a zeolite, a polymer, or a polymer composite.
4. The method of claim 3 , wherein the first material comprises a phosphate compound, a polymer, or a combination thereof.
5. The method of claim 1 , wherein the second material comprises a combination of at least two different compounds.
6. The method of claim 1 , wherein the second material comprises at least one compound chosen from silica, alumina, zirconia, glass, diamond, silicon carbide, a carbon fiber composite, titanium, stainless steel, hardened steel, or a chromium alloy.
7. The method of claim 1 , wherein the article comprises a metal or metal alloy.
8. The method of claim 1 , wherein the first material comprises a compound having at least one functional group, such that impregnating the surface with the first material provides the surface with a chemical property of the at least one functional group.
9. The method of claim 8 , wherein the at least one functional group comprises a siloxane functional group.
10. The method of claim 1 , further comprising adhering a third material to the surface after delivering the first and second sets of particles.
11. The method of claim 10 , wherein the third material comprises a paint or a polymer.
12. The method of claim 1 , wherein the portion of the surface removed comprises an oxide.
13. The method of claim 1 , wherein the weight ratio of first material to second material ranges from 60:40 to 40:60.
14. The method of claim 1 , wherein delivering the first and second sets of particles bonds the first material to the surface.
15. The method of claim 14 , wherein the second material has a Mohs hardness ranging from 5 to 10.
16. A method of treating a surface of an article, the method comprising:
delivering substantially simultaneously a first set of particles comprising a first material and a second set of particles comprising a second material different from the first material from at least one fluid jet to the surface of the article, wherein the first material comprises a polymer;
removing a portion of the surface with the second set of particles to allow the first set of particles to impregnate the surface;
impregnating the surface with the first set of particles; and
adhering a third material to the surface.
17. The method of claim 16 , wherein the second material has a Mohs hardness ranging from 5 to 10.
18. The method of claim 16 , wherein the second set of particles are irregular in shape.
19. A method of treating a surface of an article, the method comprising:
delivering substantially simultaneously a first set of particles comprising a first material and a second set of particles comprising a second material different from the first material from at least one fluid jet to the surface of the article, wherein the second set of particles are irregular in shape;
removing a portion of the surface with the second set of particles to allow the first set of particles to impregnate the surface;
impregnating the surface with the first set of particles to form a layer of the first material bound to the surface; and
adhering a third material to the layer of the first material.
20. The method of claim 19 , wherein the third material comprises a polymer.
