    摘要: A mechanical seal includes a pair of opposing seal faces, wherein at least one of the pair of seal faces comprises a multilayer coating disposed on a substrate, and wherein the multilayer coating comprises a periodic repetition of distinct layers. In another embodiment, the mechanical seal includes a pair of opposing seal faces, wherein at least one of the pair of seal faces comprises a multilayer coating disposed on a substrate, wherein the multilayer coating comprises a plurality of layers of a composite, and wherein no two adjacent layers of the composite comprise an identical ratio of composite constituents. A method includes disposing a multilayer coating on a substrate to form at least one of a pair of opposing seal faces of a mechanical seal.

    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: Cement is conditioned, cured and/or tested while applying a specified temperature and/or pressure. In certain embodiments, the specified temperature and/or pressure applied during the testing substantially simulates anticipated static downhole conditions the cement will be subjected to in use. In certain embodiments, the specified temperature and/or pressure applied during the receiving substantially simulates pumping placement conditions the cement will be subjected to in use. In certain embodiments, the cement can be conditioned in a conditioning vessel while applying specified temperature and/or pressure to the cement. In certain embodiments, the temperature and/or pressure applied in the conditioning substantially simulates anticipated pumping placement conditions the cement will be subjected to in use.
