摘要:
A cast component includes a cast structure having a primary geometry formed by a mold. Also included is a structural deposit formed by cold spraying one or more layers of powdered material on an outer surface of the cast structure, the structural deposit defining at least one feature of the overall outer geometry of the cast component in addition to the primary geometry. Also provided are methods of manufacturing the cast component.
摘要:
The invention relates to a method for the deposition of thin films, comprising preparing a solution containing at least one transition metal oxide powder in a solvent, continuously stirring said solution in order to form a sol, and using said sol in the form of said transition metal oxide film, characterised in that the powder is subjected to a preliminary preparation step.

There is discloses a coating on mono- or poly-crystalline diamond or diamond-containing material. The coating comprises a first adhesive layer formed directly on the diamond or diamond-containing material, the first layer comprising tungsten and tungsten carbide alloyed with fluorine in an amount of 0.001 to 0.12wt% calculated on the total weight of the first layer. The coating further comprises a second protective layer formed on the first layer, the second layer comprising at least tungsten alloyed with fluorine in an amount of 0.001 to 0.12wt% calculated on the total weight of the second layer. The adhesive layer provides excellent bond strength to diamond, while the protective layer provides good protection against oxidation and molten metals used for attaching the coated diamonds to tools.
摘要:
An Al-plated steel sheet includes: a steel sheet; an Al plating layer which is formed on one surface or both surfaces of the steel sheet and contains at least 85% or more of Al by mass%; and a surface coating layer which is laminated on the surface of the Al plating layer and contains ZnO and one or more lubricity improving compounds.
摘要:
With regard to a surface hardening method that a surface of an engine member is coated with an alloy layer having high abrasive resistance so as to improve life of the member and a production method of a piston or the like that abrasive resistance of the member is improved by the hardening method, a surface of a metal base material is coated uniformly with mixture including metal powder, a binder and solvent so as to form a coat, and the coat is dried and applied thereon with laser or electron beam so as to be sintered and dispersed for forming an alloy layer on a surface of the metal base material and for bonding the alloy layer to the metal base material.
摘要:
A conductive metal layer is formed on a substrate having a softening point above about 200°C by depositing copper or nickel particles on the substrate, and heating and pressing the metal particles. Unlike similar methods, no developing agent is required to render the metal layer conductive. The coated substrates are useful for a variety of uses such as EMI shielding and printed circuit boards.
摘要:
The surfaces of articles of manufacture fabricated from aluminum or other metals which are not permanently hydrophilic are made permanently hydrophilic by coating the surfaces with a continuous film containing particles of activated alumina. The coated articles are not only hydrophilic, but also have good corrosion resistance and exhibit low abrasiveness, resulting in decreased wear on manufacturing tools, such as dies.
