摘要:
A material and method for adhering at least two materials that includes the step of interposing at least one intermediate layer between the two materials and associated adhesion material. The materials to be adhered exhibit at least one characteristic dissimilarity and the intermediate material interposed contains at least one shape memory alloy, the shape memory alloy capable of exhibiting superelasticity.
摘要:
A method of surface treating heat treated members to remove oxide scale. The heat treated members are subjected to a staged series of discrete chemical and physical cleaning steps yielding a substantially scale-free surface readily adaptable for subsequent application of protective coatings.
摘要:
Disclosed is a method of making a coated substrate, especially a diamond coated substrate. In one embodiment, the method includes depositing an interlayer on a substrate to create an interlayer surface, peening the interlayer surface with a peening compound to create a peened interlayer surface, and depositing a coating on the peened interlayer surface to create a coated substrate wherein the peening compound comprises particles of the coating. Also provided is a method of drilling a nonferrous substrate such as aluminum with no more than minimum lubricants. The method includes providing a diamond coated drill produced by the foregoing method, and moving the drill against a nonferrous substrate under sufficient force such that the drill cuts and removes a portion of the substrate, wherein the moving of the drill against the substrate occurs under minimum lubrication conditions.
摘要:
A belt for a continuously variable transmission (CVT) includes at least one continuous band supported against a contact face in a slot formed in each of a plurality of transverse elements of the CVT. The band has a surface positioned against the contact face. This surface is coated with chromium nitride by physical vapor deposition to reduce wear.
摘要:
A diamond coated cutting tool is disclosed having a either steel or cemented carbide substrate. The interior layer disposed between the diamond coating and the substrate inhibits the diffusion of carbon and other species.
摘要:
A surface of an article is heated and subjected to pressure by operation of a friction stir tool. The pressure of the face of the tool on the article surface, and the speed of rotation of the tool and of its progression along the surface of the article, are controlled to progressively hot-work a specified surface area. The face of the tool may be round and have a profiled, axially extending, smaller diameter pin for higher concentration of frictional heat and load and for plasticizing a surface layer of the workpiece. Such hot work may be applied for reducing surface porosity or for producing another change in the surface microstructure, or for effecting another change in surface material properties.
摘要:
A metallic nanowire having an aspect ratio of at least 100 and a diameter less than 200 nanometers composed of at least one of bismuth, indium, tin, lead, zinc, antimony and alloys of the same and a method of making the same from a thin film composite.
摘要:
Methods and systems for enhancing water management capabilities of a fuel cell are disclosed. The methods include changing the surface energy of a fuel cell element by depositing, via physical vapor deposition, a thin film on the surface of the fuel cell element. Sputtering and evaporation can be employed as the physical vapor deposition technique.
