First claim
Opening claim text (preview).
What is claimed is: 1. An article for a gas turbine engine, comprising: a substrate, and a nickel phosphorous coating disposed on the substrate, the nickel phosphorus coating having a columnar microstructure, wherein the coating includes at least one region of pure nickel interspersed with columns of the columnar microstructure. 2. The article of claim 1 , wherein the columnar microstructure includes columns arranged approximately parallel to a plane of the substrate. 3. The article of claim 1 , wherein the coating is between about 1 and 5 mils (25.4 to 127 microns) thick. 4. The article of claim 1 , wherein the substrate comprises a titanium alloy, a nickel alloy, a steel alloy, or combinations thereof. 5. The article of claim 1 , wherein the substrate comprises a titanium alloy. 6. The article of claim 1 , wherein the coating has a hardness between about 750 and 1100 HV. 7. The article of claim 1 , wherein the coating provides corrosion resistance to the substrate. 8. The article of claim 7 , wherein the coating provides mechanical protection to the substrate. 9. The article of claim 1 , wherein the article is a component of a bearing system of the gas turbine engine. 10. The article of claim 1 , wherein the article is a component of a vane in a compressor or turbine of the gas turbine engine.
