摘要： A process for providing a protective layer to an article. The process includes depositing a layer of material onto a surface of the article with a thermal spray process. Examples of thermal spray process include high velocity oxygen/air fuel, atmospheric plasma spray, and chemical vapor deposition. Coating methods, such as cold vapor deposition and physical vapor deposition, may also be used. The layer can then be bonded to the article by heating material in the layer adjacent its connection with the article. Bonding the layer to the article can be performed by irradiating the layer with a collimated light source, the layer irradiation can be applied concurrently with the thermal spray process

摘要： A method of recovering rhenium from rhenium-containing superalloy scrap is provided. The superalloy is usually a nickel-based superalloy. The method includes the steps of forming an oxidation feedstock of flaky morphology of the superalloy scrap, and oxidizing the oxidation feedstock to convert rhenium into a volatile rhenium oxide. The flaky morphology of the oxidation feedstock is achieved by increasing the surface area of the superalloy scrap.

摘要： A gate valve has a body, the body having a cavity and a flow passage intersecting the cavity. A seat is mounted to the body at the intersection of the flow passage and the cavity. A gate is installed at the cavity and has an engaging face that slidingly engages the seat while the gate is being moved between open and closed positions. The end faces between a seat pocket and the seat are hard-coated and smooth-finished to provide sealing when mated. The hardcoated pocket and seat sealing surfaces extend the life of the valve by eliminating the need for an elastomeric seal of limited life.
