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 (300). Forming the first layer (300) includes applying virgin powder particles (204) containing at least one rare-earth doped ceramic oxide (206) onto the substrate (200). Forming the second layer (302) includes applying recycled powder particles (208) containing the at least one rare-earth doped ceramic oxide (206) and at least one extraneous material (210) onto the first layer (300). Another coating method is disclosed including mixing the virgin powder particles (204) with the recycled powder particles (208) to form a mixture of powder particles (212), and applying the mixture of powder particles (212) onto the substrate (200). A coated article (100) is disclosed including a substrate (200) and a coating (202) on the substrate (200), 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).
