Abstract: A method is disclosed for preventing harm caused by constrictions in the cooling holes of gas-cooled parts, in particular of gas turbines and/or burners. These constrictions form because the walls of the gas-cooled parts through which the cooling holes extend and which are covered on their outside with a protective, first coating are provided during the course of an overhaul with a second, repeat coating, and coating material is deposited in the cooling holes. Constant flow ratios in the cooling holes are achieved in a simple manner in that prior to the overhaul, the cooling holes are constricted with first means to an extent that corresponds to the later constrictions created during the course of the second coating. The first means are removed after the overhaul. The first means takes the form of an insert with holes that constrict the flow through the cooling holes.

Abstract: A process for forming a diffusion aluminide coating on an article, such as a component for a gas turbine engine. The process is a vapor phase process that generally entails placing the article in a coating chamber containing an aluminum donor material, without any halide carrier or inert filler present. The aluminum donor material consists essentially of about 20 to about 70 weight percent aluminum, with the balance being chromium or cobalt. While the article is held out of contact with the donor material, coating is initiated in an inert or reducing atmosphere by heating the article and the donor material to vaporize the aluminum constituent of the donor material, which then condenses on the surface of the article and diffuses into the surface to form a diffusion aluminide coating on the article.

The polymeric material of the topcoat can be a biostable, biocompatible material which provides long term non-thrombogenicity to the device portion during and after release of the biologically active material.

Abstract: Coatings of scarcely crystalline carbonated hydroxyapatite are deposited on metallic or ceramic substrates, by immersing the substrates in a solution containing calcium phosphate and bicarbonate ions, with a molar ratio calcium/phosphate from 0.8 to 2 and a pH from 6.8 to 8.0. Subsequently, the solution is heated to 50-80° C., thus raising the pH and causing a spontaneous deposition of carbonated hydroxyapatite on the substrates. The obtained coatings are highly biocompatible, osteoconductive, bioactive and biodegradable, and can be utilized in structures used for preparing orthopaedic and dental prostheses and implants.

Abstract: A method for restoring a protective coating including a metallic environmental resistant coating of a coating total thickness within a coating design thickness range on a metal substrate of an article includes the application of a replacement material to at least one discrete local surface area on which an undesirable amount of degradation has occurred. Such degradation can extend through the protective coating into the metal substrate. The degradation product can include at least one of oxidation, coating rumpling, and coating voiding, for example, rumpling or voiding of a bond coat under a ceramic thermal barrier coating (TBC). The degradation product first is conditioned at the discrete local area to expose an underlying portion while retaining at least a portion of the metallic environmental coating on surface areas adjacent the discrete surface area. Then a replacement metallic environmental resistant material is applied, retaining the coating total thickness within the coating design thickness range.
