Abstract:
Surfaces which have substantially continuous frictional contact, eg. reciprocating engine parts, are coated with a solid film lubricant having excellent wear characteristics and adhesion. The parts in question may be pistons, and the area to which the wear resistant solid lubricant film is bonded is the piston skirt -- i.e., all or a portion of the area below the piston rings. The lubricant is composed of a polyimide derived from 2,2-bis[4-(4-amino- phenoxy)phenyl]hexafluoropropane ("4-BDAF") and an aromatic tetracarboxylic acid (or dianhydride or ester thereof) containing fluorinated carbon.
Abstract:
Hochtemperaturschmierstoff für die spanlose Heissumformung von Metallen, der vorzugsweise Form einer in wässriger Dispersion angewendet wird. Um einerseits ein Koagulieren der Feststoffe in der wässrigen Dispersion zu vermeiden, und andererseits einen temperaturbeständigen gleichmässigen Schmierfilm zu erhalten, enthält der Hochtemperaturschmierstoff neben einem Festschmierstoff einem rückstandsfrei sich zersetzenden organischen Produkt zusätzlich einen anorganischen Zusatz aus Polyphosphat, einer Borverbindung und einem Alkalisilikat, sowie ein organisches Stabilisierungsmittel.
Abstract:
A threaded joint for steel pipes comprised of a pin 1 and a box 2 each having a threaded portion (1a, 2a) and an unthreaded metal contact portion (1b, 2b) exhibits adequate leakage resistance and galling resistance when used for makeup of oil country tubular goods with application of a green dope or even without any dope. The threaded joint has a first plating layer of Sn-Bi alloy plating or Sn-Bi-Cu alloy plating formed on the contact surface of at least one of the pin 1 and the box 2. The first plating layer may have a second plating layer selected from Sn plating, Cu plating, and Ni plating on its lower side and at least one layer of a lubricating coating, and particularly a solid lubricating coating, on its upper side.
Abstract:
A lubricant coating disposed between a substrate and a counter surface comprises a reaction layer immediately adjacent the substrate. A bonding layer is immediately adjacent the reaction layer, with the bonding layer comprising a first composition. A low friction, lubricious layer is immediately adjacent the bonding layer, with the lubricious layer comprising a second composition that is different from the first composition.
Abstract:
The present invention provides lubricant compositions for the powder metallurgical field. The lubricant compositions contain a solid phase lubricant such as graphite, molybdenum disulfide, and polytetrafluoroethylene in combination with a liquid phase lubricant that is a binder for the solid phase lubricant. The binder can be chosen from various classes of compounds including polyethylene glycols, polyethylene glycol esters, partial esters of C3-6 polyhydric alcohols, polyvinyl esters, and polyvinyl pyrrolidones. The binder is solubilized in an organic solvent.
