Abstract
Official abstract text for this publication.
A coating including a structural matrix having a porosity and a solid lubricant that at least partially fills the porosity.
First claim
Opening claim text (preview).
What is claimed: 1 . A coating, comprising: a structural matrix having a porosity; and a solid lubricant that at least partially fills said porosity. 2 . The coating as recited in claim 1 , wherein said structural matrix is reticulated. 3 . The coating as recited in claim 1 , wherein said porosity is between about 8%-40% open. 4 . The coating as recited in claim 1 , wherein said porosity is at least about 15% open. 5 . The coating as recited in claim 1 , wherein said structural matrix is manufactured of a nickel alloy. 6 . The coating as recited in claim 5 , wherein said structural matrix is about 0.03 inches thick. 7 . The coating as recited in claim 1 , wherein said structural matrix is manufactured of a cobalt alloy. 8 . The coating as recited in claim 7 , wherein said structural matrix is about 0.03 inches thick. 9 . The coating as recited in claim 7 , wherein said structural matrix is thermal sprayed. 10 . The coating as recited in claim 9 , wherein said structural matrix is between about 0.003-0.01 inches thick. 11 . The coating as recited in claim 1 , wherein said solid lubricant is mechanically retained within said structural matrix. 12 . The coating as recited in claim 1 , wherein said solid lubricant includes at least one of h-BN, CuO, ZnO, MgO, MnO2, and B2O3. 13 . The coating as recited in claim 1 , wherein said solid lubricant is vacuum impregnated into said structural matrix. 14 . A method to manufacture a coating, comprising: applying a structural matrix having a porosity to a substrate; and at least partially filling the porosity with a solid lubricant. 15 . The method as recited in claim 14 , wherein the applying includes thermal spraying. 16 . The method as recited in claim 14 , wherein the applying includes additive manufacturing. 17 . The method as recited in claim 14 , wherein the at least partially filling includes vacuum impregnation. 18 . The method as recited in claim 14 , wherein the at least partially filling includes forming a liquid suspension with the solid lubricant. 19 . The method as recited in claim 18 , further comprising applying a vacuum such that air in the pores is evacuated and replaced with the liquid suspension. 20 . The method as recited in claim 19 , wherein the at least partially filling includes adding a binder to the solid lubricant.
