Abstract: Buffer layer architectures are epitaxially deposited on biaxially-textured rolled-Ni and/or Cu substrates for high current conductors, and more particularly buffer layer architectures such as MgO/Ag/Pt/Ni, MgO/Ag/Pd/Ni, MgO/Ag/Ni, MgO/Ag/Pd/Cu, MgO/Ag/Pt/Cu, and MgO/Ag/Cu. Techniques used to deposit these buffer layers include electron beam evaporation, thermal evaporation, rf magnetron sputtering, pulsed laser deposition, metal-organic chemical vapor deposition (MOCVD), combustion CVD, and spray pyrolysis.

Abstract: An apparatus for applying powder to at least an interior surface of a hollow object includes a powder discharge device adapted to receive powder and discharge the powder through an outlet. An object holder is configured to hold the object such that the outlet is positioned within the hollow object adjacent the interior surface. A rotating mechanism is configured to engage and rotate the hollow object such that the powder discharged from the outlet coats the interior surface as the interior surface rotates past the outlet. The powder discharge device may be a powder fluidizing bed unit including a chamber with a powder discharge opening in the form of an elongate slot.

Abstract: A method of lubricating the wall surfaces of a die cavity used in powder metallurgy involves spraying the wall surfaces with tribocharged particles of a lubricant material. The method is carried out by means of an apparatus centered about a plug member which has a three-dimensional shape conforming generally to that of the article to be formed. The plug member is slightly smaller than the article so that when the plug member is inserted into the die cavity there is a small, but uniform, gap created between the outer wall surfaces of the plug member and the walls of the die cavity. The plug member is secured to a closing plate which can be inserted into the die cavity so as to be sealed therewith. The closing plate is provided with vent holes and the plug member has a plurality of spaced apart tubes extending therethrough, which tubes exit at one or more of the wall surfaces of the plug member. The lubricant material is fed using an inert gas under pressure through tubing which tribocharged the lubricant particles and the tribocharged particles are sprayed from the tubes in the plug member into the gap so that they are electrostatically attracted to the walls of the die cavity and adhere thereto. Any excess gas and lubricant exits the gap through the vent holes in the closing plate. A uniform thin coating of lubricant is created on the walls of the die cavity. The green density of the article formed in the die is greater, and the ejection force required to remove the formed article from the die cavity is less, than with existing methods and apparatus.

Abstract translation: 用于粉末冶金中使用的模腔的壁表面润滑的方法包括用滑动摩擦的润滑剂材料的颗粒喷洒壁表面。 该方法通过围绕具有与要形成的制品的立体形状一致的三维形状的塞子构件的装置进行。 插头构件比制品稍小，使得当插头构件插入模腔中时，在插塞构件的外壁表面和模腔的壁之间产生小而均匀的间隙。 插头构件被固定到可以插入模腔中以与其密封的封闭板。 封闭板设置有通气孔，并且插塞构件具有延伸穿过其中的多个间隔开的管，该管在插塞构件的一个或多个壁表面处离开。 润滑剂材料在加压下通过管道将惰性气体进料，该管道摩擦了润滑剂颗粒，并且将摩擦电荷的颗粒从插塞构件中的管道喷射到间隙中，使得它们被静电吸引到模腔的壁并粘附到其上 。 任何多余的气体和润滑剂通过封闭板上的通气孔离开间隙。 在模腔的壁上产生均匀的薄涂层润滑剂。 在模具中形成的制品的生坯密度更大，与现有的方法和装置相比，从模腔移出成形制品所需的喷射力较小。
