    Abstract: A tubular threaded joint has a pin and a box. Each having a contact surface comprising a threaded portion and an unthreaded metal contact portion including a seal portion and a shoulder portion. A solid lubricating coating having a relatively high Knoop hardness is formed on a portion including the shoulder portion of the contact surface, such as the unthreaded metal contact portion including the shoulder portion and the seal portion, of at least one of the pin and the box. A solid lubricating coating having a relatively low Knoop hardness is formed at least on the remaining portion of the contact surface, such as the threaded portion. The threaded joint has excellent galling resistance, gas tightness, and rust preventing properties. The joint does not readily undergo yielding of shoulder portions even when made up with a high torque, thereby making it possible to perform makeup in a stable manner.

    Abstract: A piston for an internal combustion engine includes a piston base material and a film of lubrication coating composition. The coating composition has an inner coating layer formed on a surface of the piston base material and an outer coating layer formed on a surface of the inner coating layer. Each of the inner coating layer and the outer coating layer contains at least one of a polyamide-imide resin, a polyimide resin and an epoxy resin as a binder. The inner coating layer contains 0 to 50 wt % of at least one of graphite and molybdenum disulfide as a solid lubricant, whereas the outer coating layer contains 50 to 95 wt % of at least one of graphite and molybdenum disulfide as a solid lubricant.
