Abstract

The present disclosure presents a method and a system for modifying a surface of a substrate. The method includes an act of abrasive blasting of a part of the surface of the substrate. In the abrasive blasting, an abrasive media is provided to the part of the surface. The abrasive media is carried to the part by a first carrier. The abrasive media collides with the part of the surface and causes abrasion to the part of the surface. In the method, the first carrier includes steam. The steam of the first carrier heats the part of the surface.

First claim

The invention claimed is:

1. A method for modifying a surface of a substrate, the method comprising:
providing an abrasive media carried by a first carrier to a part of the surface of the substrate, wherein the first carrier comprises steam;
abrasive blasting the part of the surface of the substrate, wherein the abrasive media collides with the part of the surface and causes an abrasion to the part of the surface;
providing an additive carried by a second carrier to the part of the surface of the substrate, wherein the second carrier comprises steam; and
forming a coating with the additive on the part of the surface of the substrate.

2. The method of claim 1 , wherein the steam of the first carrier is saturated, the steam of the second carrier is saturated, or both the steam of the first carrier and the steam of the second carrier are saturated.

3. The method of claim 1 , wherein the steam of the first carrier is superheated, the steam of the second carrier is superheated, or both the steam of the first carrier and the steam of the second carrier are superheated.

4. The method of claim 3 , wherein the superheated steam of the first carrier and/or the superheated steam of the second carrier is generated by burning a fuel in form of a burning mixture and injecting saturated steam or atomized water into the burning mixture.

5. The method of claim 1 , wherein the steam of the first carrier and the steam of the second carrier are received from a common source of steam.

6. The method of claim 5 , wherein the common source of steam is operated at a pressure ranging between 3 bars and 30 bars.

7. The method of claim 5 , wherein the common source of steam is operated at a temperature ranging between 100° C. and 300° C.

8. The method of claim 1 , further comprising:
providing a protective environment to the part of the surface by enveloping the part of the surface with a non-reactive material, a reducing material, or both the non-reactive material and the reducing material.

9. The method of claim 1 , further comprising:
providing the substrate, wherein the substrate is a metallic substrate.

10. The method of claim 9 , wherein the metallic substrate comprises aluminum, magnesium, or a combination thereof.

11. The method of claim 1 , wherein the abrasive media comprises alumina grits, steel-based grits, quartz, silicon carbide, ceramic granules, a polymer, or a combination thereof.

12. A system for modifying a surface of a substrate, the system comprising:
an abrasive blasting module configured to provide an abrasive media carried by a first carrier to a part of the surface of the substrate, wherein the first carrier comprises steam; and
an additive providing module configured to provide an additive carried by a second carrier to the part of the surface of the substrate,
wherein the second carrier comprises steam,
wherein the additive is configured to interact with the substrate to form a coating on the part of the surface of the substrate, and
wherein the abrasive blasting module and the additive providing module are in fluid communication with a common source of steam.

13. The system of claim 12 , further comprising:
a moving mechanism configured to implement a change in relative orientation between the part of the surface of the substrate with respect to the abrasive blasting module and the additive providing module,
wherein the abrasive blasting module and the additive providing module are in a fixed orientation relative to each other.

14. The system of claim 13 , further comprising:
a pre-coating protection module configured to provide a non-reactive material, a reducing material, or both the non-reactive material and the reducing material to the part of the surface of the substrate such that the non-reactive material, the reducing material, or both the non-reactive material and the reducing material envelop the part of the surface of the substrate.

15. The system of claim 12 , further comprising:
a pre-coating protection module configured to provide a non-reactive material, a reducing material, or both the non-reactive material and the reducing material to the part of the surface of the substrate such that the non-reactive material, the reducing material, or both the non-reactive material and the reducing material envelop the part of the surface of the substrate.
