    Abstract: Provided are a formulation which creates protection layers on the metal friction and wear surface and a method for preparing the same. The formulation provided here comprises 45-99 parts laminar hydroxyl silicate powders, 1-50 parts formulation which creates protection layers on the metal surface and method for preparing the same and 0.05-6 parts carbonization-graphitization catalyst, calculated by weight. Also provided is method for preparing the same. The formulation provided here could create a friction-reducing and wear-resistant nanocrystal protection layer in situ on the metal friction and wear surface, at the same time, it has high hardness of cermet and elastic modulus of formulation which creates protection layers on the metal surface and method for preparing the same high grade alloy steel.

    Abstract: A threaded joint for steel pipes comprising a pin 1 and a box 2 each having a contact surface comprising a threaded portion 3 or 4 and an unthreaded metal contact portion 8 is provided with improved anti-galling propertied by forming a lubricating coating on the contact surface of at least one of the pin and the box, the lubricating coating exhibiting a self-repairing function by liquid lubrication and having a decreased greasiness. The lubricating coating is (1) a coating which comprises a lower lubricant layer which is in liquid form in the temperature range of above 0° C. and below 40° C. and an upper lubricant layer which is in solid form at 40° C., or (2) a coating which is semi-solid or solid at 40° C. and is formed of a mixture comprising a lubricating oil which is in liquid form in the temperature range of above 0° C. and below 40° C. and a wax which is in solid form at 40° C., the mixture preferably having been heated so as to liquefy the wax and dissolve in each other the wax and lubricant oil.
