Abstract

A restoration process for restoring surface porosity defects on a component surface. The areas of a component surface having surface porosity defects are identified for restoration. The restoration surface is subsequently sprayed with a restoration spray to restore the surface porosity defects. The component surface is then finished to create a final component substantially free of surface porosity.

Claims (26)

1. An in-line restoration process for repairing surface porosity defects in a cast component, the process comprising the steps of: identifying an area on a component surface containing at least one porosity defect resulting from the casting process, the area defining a restoration area; applying a restoration spray to said restoration area; and immediately finishing said restoration area, wherein the component surface and the restoration spray comprise distinct compositions.

2. The process of claim 1 , wherein the component surface comprises a metallic substrate and the restoration spray comprises a metallic filler.

3. The process of claim 1 , wherein the component surface comprises a metallic substrate and the restoration spray comprises a polymeric filler.

4. The process of claim 3 , wherein the polymeric filler is a thermoplastic filler.

5. The process of claim 4 , wherein the thermoplastic filler is a polyamide or polyphthalamide filler.

6. The process of claim 1 , wherein the component surface comprises a polymeric substrate and the restoration spray comprises a metallic filler.

7. The process of claim 1 , wherein the component surface comprises a polymeric substrate and the restoration spray comprises a polymeric filler.

8. The process of claim 7 , wherein the polymeric filler is a thermoplastic filler.

9. The process of claim 8 , wherein the thermoplastic filler is a polyamide or polyphthalamide filler.

10. The process of claim 1 , wherein the component surface is cast iron or steel and the restoration spray comprises a nickel alloy or copper alloy.

11. The process of claim 10 , wherein the nickel or copper alloy is based on the Ni—Cu binary system.

12. The process of claim 1 wherein said cast component is cast utilizing a lost foam casting process, a sand casting process, a die casting process or a permanent mold casting process.

13. The process of claim 1 wherein the step of applying a restoration spray further comprises applying the spray with a spray gun.

14. The process of claim 13 wherein the step of finishing the restoration area further comprises removing excess restoration spray material.

15. An in-line restoration process for repairing surface porosity defects on a sealing surface requiring zero porosity tolerance, the process comprising the steps of: identifying an area on a sealing surface containing at least one porosity defect, the area defining a restoration area; applying a restoration spray to said restoration area; and immediately finishing said restoration area.

16. The process of claim 15 , wherein the sealing surface comprises a metallic substrate and the restoration spray comprises a separate, distinct metallic filler.

17. The process of claim 15 , wherein the sealing surface comprises a metallic substrate and the restoration spray comprises a polymeric filler.

18. The process of claim 17 , wherein the polymeric filler is a thermoplastic filler.

19. The process of claim 18 , wherein the thermoplastic filler is a polyamide or polyphthalamide filler.

20. The process of claim 15 , wherein the sealing surface comprises a polymeric substrate and the restoration spray comprises a polymeric filler.

21. The process of claim 20 , wherein the polymeric filler is a thermoplastic filler.

22. The process of claim 21 , wherein the thermoplastic filler is a polyamide or polyphthalamide filler.

23. The process of claim 15 , wherein the sealing surface comprises a polymeric substrate and the restoration spray comprises a metallic filler.

24. The process of claim 16 , wherein the sealing surface is cast iron and the restoration spray comprises a nickel alloy filler.

25. The process of claim 15 wherein the step of finishing the restoration area further comprises removing excess restoration spray material.

26. The process of claim 15 wherein the sealing surface is a mating surface that requires use of a gasket.
