Abstract
Official abstract text for this publication.
A method for forming an abrasive surface includes utilizing an energy source to form a melt pool layer in a substrate and applying abrasive grit into the melt pool layer. A method for forming an abrasive surface including applying an abrasive grit to a substrate and utilizing an energy source to form a melt pool layer in the substrate without disturbing the abrasive grit such that the abrasive grit becomes embedded in the melt pool layer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for forming an abrasive surface, comprising: utilizing an energy source to form a melt pool into a substrate; and applying an abrasive grit into the melt pool, the melt pool of a thickness less than the grit size of the abrasive grit. 2. The method as recited in claim 1 , wherein the abrasive grit includes cubic boron nitride (cBN). 3. The method as recited in claim 1 , wherein the energy source includes a laser. 4. The method as recited in claim 1 , wherein the energy source includes magnetic induction. 5. The method as recited in claim 1 , wherein the melt pool is 20 to 200 μm in depth. 6. The method as recited in claim 1 , wherein the substrate is an airfoil. 7. The method as recited in claim 6 , wherein the substrate is a tip of the airfoil. 8. The method as recited in claim 1 , wherein applying the abrasive grit includes varying a concentration of the abrasive grit. 9. The method as recited in claim 1 , wherein applying the abrasive grit includes varying a type of abrasive grit. 10. The method as recited in claim 1 , wherein applying the abrasive grit includes applying the abrasive grit in a predetermined pattern. 11. The method as recited in claim 1 , wherein abrasive grit becomes partially embedded in the melt pool. 12. The method as recited in claim 1 , further comprising: adding metal powder onto the substrate around the abrasive grit; and melting the metal powder in place to increase retention of the abrasive grit such that the abrasive grit extends to form the abrasive surface. 13. A method for forming an abrasive surface, comprising: applying an abrasive grit to a substrate; and utilizing an energy source to form a melt pool in the substrate without disturbing the abrasive grit as the abrasive grit does not obscure the energy source such that the abrasive grit becomes partially embedded in the melt pool to form the abrasive surface, the melt pool of a thickness less than the grit size of the abrasive grit. 14. The method as recited in claim 13 , wherein the abrasive grit includes cubic boron nitride (cBN). 15. The method as recited in claim 13 , wherein the energy source includes a laser. 16. The method as recited in claim 13 , wherein the energy source includes magnetic induction. 17. The method as recited in claim 13 , wherein the melt pool is between about 20 to 200 μm in depth. 18. The method as recited in claim 13 , wherein the substrate is an airfoil. 19. The method as recited in claim 18 , wherein the substrate is a tip of the airfoil. 20. The method as recited in claim 13 , wherein applying the abrasive grit includes varying a concentration of the abrasive grit. 21. The method as recited in claim 13 , wherein applying the abrasive grit includes varying a type of abrasive grit. 22. The method as recited in claim 13 , wherein applying the abrasive grit includes applying the abrasive grit in a predetermined pattern via a computer aided manufacturing system.
