Abstract:
In a thermal spray process, a wire (14) is fed into a flame-jet (20) to heat said wire (14) to the melting point, atomize and projected high velocity the droplets so formed against a surface (28) to buildup a coating of material (24) on the surface (28). The wire (14) is fed into the flame by aligning the cast-plane of the wire (14) with the flame-jet (20) by using a tubular member formed into a circular shape (30) to provide sufficient length to guide wire (14) and to provide the necessary twist amount to the wire (14) to align the cast-plane with the axis of the flame-jet (20).
Abstract:
The invention concerns a process for coating an object with a layer of fluorine containing material at elevated temperature. The material applied for coating has a measurable vapour pressure at elevated temperature and contains organic fluorine.
Abstract:
A modified chemical vapor deposition (CVD) method and various coatings formed by this method are disclosed. A uniform coating is obtained by the disclosed CVD method by redirecting the energy source and/or the hot gasses produced thereby. The methods disclosed are particularly useful for forming thin film, insulative, oxide coatings on the surface of conductive or superconductive wires. The redirect methods are also useful for producing powders that can be collected for further processing. Metal oxide barrier coatings for polymer food containers are also disclosed.

Abstract:
An article includes a body that has a coating thereon. The coating has a first portion disposed on a first section of the body and a second portion disposed on a second, different section of the body. The first portion has a first microstructure and the second portion has a second, different microstructure.
Abstract:
Presented are nano-composite coatings to improve wear and corrosion resistance of high-strength steel parts or other substrate including the non-line-of-sight (NLOS) regions thereof. The disclosed nano-composite coatings are shown to have a 3x to 5x improvement in wear rate compared to hard chrome. The invention includes the use of the directed vapor deposition (DVD) technique to deposit nano-composite coatings to substrates. Also presented are nano-composite coatings applied in layers of film of differing thickness and composition. Wear of the layers of film and thus, remaining life of the coating may be determined by resistance or spectroscopy.
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:
The invention relates to an apparatus (1 ) and a method for providing the surface of glass (2) with a coating. In the method, at least one liquid raw material (3) is atomized by means of at least one gas-dispersing atomizer (6) into aerosol that is discharged from an atomizing head (34) of the atomizer (6). The drop size of the aerosol discharged from the atomizing head (34) of the atomizer (6) is reduced by changing the hydrodynamic properties of the aerosol flow by means of flow restraints (36), and the aerosol is conducted onto the surface of a glass product (2), where the aerosol reacts forming a coating onto the surface of the glass product (2).

Hybrid chemical vapor deposition systems for depositing a semiconductor-containing thin film over a substrate comprise a reaction space, a substrate support member configured to permit movement of a substrate in a longitudinal direction and a plasma-generating apparatus disposed in the reaction space and configured to form plasma-excited species of a vapor phase chemical. The systems further comprise a hot wire unit disposed in the reaction space and configured to heat and decompose a vapor phase chemical. The hot wire unit can be a filament. The systems can further comprise an additional reaction space proximate the reaction space. The additional reaction space can comprise a plasma-generating apparatus configured to form plasma-excited species of a vapor phase chemical and a hot wire unit configured to heat and decompose a vapor phase chemical.
