Abstract

A coating method is disclosed, including forming a first layer 300 on a substrate 200 and forming a second layer 302 on the first layer. Forming the first layer includes applying virgin powder particles containing at least one rare-earth doped ceramic oxide 206 onto the substrate. Forming the second layer includes applying recycled powder particles containing the at least one rare-earth doped ceramic oxide 206 and at least one extraneous material 210 onto the first layer. Another coating method is disclosed, including mixing the virgin powder particles with the recycled powder particles to form a mixture of powder particles, and applying the mixture of powder particles onto the substrate. A coated article 100 is disclosed including the substrate 200 and the coating 202 on the substrate, the coating 202 including virgin powder particles 204 of at least one rare-earth doped ceramic oxide 206 and recycled powder particles 208 including the at least one rare-earth doped ceramic oxide 206 and at least one extraneous material 210.

Description

[0001] field of invention [0002] The present invention relates to coating methods and coated articles. More particularly, the present invention relates to coating methods and coated articles comprising primary powder particles and recycled powder particles. [0003] Background of the invention [0004] The processing processes involved in certain areas of production use deposition techniques, which carry considerable waste. The ability to recycle oversprayed constituents minimizes waste disposal costs, reduces the amount of new material used and conserves natural resources. [0005] Gas turbines, such as aircraft engines and power generation systems, must meet the highest demands in terms of reliability, power, efficiency, economy and operational lifetime. The use of coatings on turbine components such as combustors, combustion liners, combustion transitions, combustion hardware, turbine blades (blades), wheels (nozzles), and shrouds is important in commercial as well as mi...
