Patent number: 11248289Abstract: A multilayered corrosion and anti-galling coating for threads and wearable materials is a liner that can be superimposed onto the surface of a device in order to protect the surface from environmental hazards. To accomplish this, the coating has a base adhesive layer, an intermediary insulation layer, an interstitial adhesive layer, and a lubricating material layer. The base adhesive layer adheres to the device's surface thus enabling the coating to form a sealing liner. The intermediary insulation layer is positioned in between the base adhesive layer and the interstitial adhesive layer. As a result, the intermediary insulation layer prevents negative chemical interactions between the base adhesive layer and the interstitial adhesive layer. The lubricating material layer is super imposed onto the interstitial adhesive layer to provide a friction-reducing coating for the device's surface.Type: GrantFiled: July 30, 2018Date of Patent: February 15, 2022Assignee: DALLAS THIN FILMSInventor: Steven Craig Shafer

Publication number: 20100231338Abstract: First, an R—Fe—B based rare-earth sintered magnet body including, as a main phase, crystal grains of an R2Fe14B type compound that includes a light rare-earth element RL, which is at least one of Nd and Pr, as a major rare-earth element R is provided. Next, an M layer, including a metallic element M that is at least one element selected from the group consisting of Al, Ga, In, Sn, Pb, Bi, Zn and Ag, is deposited on the surface of the sintered magnet body and then an RH layer, including a heavy rare-earth element RH that is at least one element selected from the group consisting of Dy, Ho and Tb, is deposited on the M layer. Thereafter, the sintered magnet body is heated, thereby diffusing the metallic element M and the heavy rare-earth element RH from the surface of the magnet body deeper inside the magnet.Type: ApplicationFiled: January 12, 2007Publication date: September 16, 2010Applicant: HITACHI METALS, LTD.Inventors: Hideyuki Morimoto, Tomoori Odaka, Masao Noumi
