Abstract:
The invention relates to a fitting, item of furniture, and/or large household appliance constructed of metal components, wherein the metal component comprises a coating at least in sections, comprising at least one perfluoralkoxy-copolymer (PFA), to a method for the production thereof, and to a fitting, an item of furniture, and/or a large household appliance.
Abstract:
A method is disclosed for applying thermal spray particles to a composite, wherein the method includes the steps of providing a composite that includes a thermally sensitive surface, and applying the thermal spray particles at a temperature that is high enough to cause a temperature-dependent change in the thermally sensitive surface of the composite. The temperature-dependent change improves adhesion between the thermal spay particles and the composite.
Abstract:

In the surface treatment system comprising a flame generating section and a basic material treating section, and a surface treatment method using it, the flame generating section comprises a fuel tank for injecting a flame deriving from a fuel gas containing a silane compound, and an injector and the basic material treating section comprises an inversion table for fixing the hardly adhesive basic material and turning it about a specified horizontal axis before and after surface treatment.
Abstract:
An article spray coated with non-melting polymers using a high velocity oxygen fuel spray gun to coat a substrate with the non-melting polymers.
Abstract:
Coatings, particularly thin films, of polymeric material are produced in accordance with the invention by applying a finely divided aerosol (N) of polymer solution to a substrate (30) and substantially simultaneously applying an energy source (38) to the applied solution to apply the solution. In cases where the polymer is cross-linking, the energy source assists in cross-linking of the polymer. The preferred energy source is a flame (38) that may optionally or desirably deposit material along with the polymer spray. One particular aspect of the invention is directed to production of polyimide films. In accordance with another aspect of the invention, the co-deposition process is used to provide thin polysiloxane coatings on glass and other substrates.
Abstract:
The invention relates to a coating material on a water basis containing molecules that have hydrophobic groups. The inventive material further comprises smaller, thermally unstable and/or volatile and/or organic molecules that interact with the hydrophobic molecules so as to bring about a stabilization in the aqueous phase.
Abstract:
A method includes masking at least one hole (209) of an article (200) with a paste, wherein the hole (209) opens onto a surface (220) of the article (200), applying a coating (260) to the surface (220) of the article (200), and removing the paste including contacting the paste with a water containing liquid/environment to dissolve or re-disperse the paste, leaving at least one open hole (209) in the surface of the coated article (200). The paste includes about 20-80wt% of a filler material, about 0.5-20wt% of a hydrogen phosphate compound, about 0.5-15wt% of a polyhydroxy compound and about 5-25wt% of water. The filler material has an average particle size in a range of about 0.1-100 microns, and includes a first material which includes alkali metal doped alumina, zirconium oxide, titanium oxide or a combination thereof and a second material which includes a silicate. A weight ratio between the first and second materials is in a range of about 1-10. A dry plug obtainable by precuring and molding the paste and suitable to be inserted into the holes is also claimed.
Abstract:
A method of applying a wear-resistant coating to aluminum sliding contact wear surfaces is disclosed. The method includes providing a plurality of parts having sliding contact wear surfaces and thermal spray coating at least one of a composite aluminum oxide and PTFE or a blend of aluminum oxide and PTFE. The disclosed method may be used to repair aluminum parts subject to sliding contact wear as well as in the design of new aluminum parts subject to sliding contact wear. Improved compressor bleed valves for gas turbine engines and improved fan exit case assemblies are also disclosed.
