Publication number: 20130273394Abstract: A method for surface treating work rolls to produce isotropic textured aluminum sheet features indenting the surface of the working rolls that produce the sheet with spherical media such as steel ball bearings having the requisite properties to avoid fracture and resulting in a smooth surface lacking facets. The spherical media can be introduced into a nip between two rolls and indent by compression, but ultrasonic peening or knurling. The aluminum sheet produced by the roll has properties that facilitate mechanical forming, such as when the sheet is processed by forming tools.Type: ApplicationFiled: May 10, 2013Publication date: October 17, 2013Inventors: Shen Sheu, Julie A.

Patent number: 8486870Abstract: Embodiments of the present invention may provide textured surfaces to be lubricated, the texturing to enhance the effectiveness of the intended nano-lubrication. The texturing may make asperities and depressions in the surface to be lubricated. This texturing may be executed, for example, by chemical etching, laser etching, or other techniques. This texturing may create locations in the lubricated surface to hold or anchor the intended nano-lubricants, to facilitate the creation of a tribo-film on the surface when the lubricated surface is used under pressure, and resulting in delivery of multiple chemistries from the nano-lubricant.Type: GrantFiled: July 2, 2012Date of Patent: July 16, 2013Inventor: Ajay P. Malshe

Publication number: 20130171473Abstract: A method for making patterns on a metal article comprises providing a metal substrate having an outer surface. A light-absorbing coating is formed on selected regions of the outer surface to reduce the surface laser reflectivity of the metal substrate. The selected regions cooperatively have a shape of a desired pattern. The selected regions are treated by laser-quenching, thereby hardening the selected regions. The outer surface is sandblasted, enabling the outer surface besides the selected regions to have a greater surface roughness than the selected regions. A metal article made by the method is also provided.Type: ApplicationFiled: August 10, 2012Publication date: July 4, 2013Applicants: FIH (HONG KONG) LIMITED, SHENZHEN FUTAIHONG PRECISION INDUSTRY CO., LTD.Inventors: QUAN ZHOU, GUI-YUN YANG, XIN-WU GUAN, PO-FENG HO
