    Abstract: A slide member of the present invention is a slide member having a substrate (10) made of a metal; and a sliding layer (20) of a resinous powder being sintered integrally on at least one of the surfaces of the substrate (10), and is characterized in that it includes a solid-lubricant powder in the sliding layer (20). Further, it can be one having an intermediate layer, which intervenes between the substrate (10) and the sliding layer (20), and which is composed of a metal differing from that of the substrate (10). The slide member of the present invention is such that the adhesiveness is high, and has good sliding characteristics. Moreover, a production process of the present invention for a slide member is characterized in that it has: a laminating step of forming a powdery sliding layer, which is composed of a resinous powder and a solid-lubricant powder at least, on at least one of the surfaces of a substrate layer, which is composed of a metal; and a sintering step of sintering the substrate layer with the powdery sliding layer integrally. In accordance with this production process, it is possible to make a slide member, which has the substrate (10) and the sliding layer (20) at least. In accordance with the production process of the present invention for a slide member, it is possible to produce a slide member whose adhesiveness is high and which has good sliding characteristics.

    Abstract: This invention relates to a threaded joint for steel pipes which comprises a pin and a box each having a contact surface including a threaded portion and an unthreaded metal contact portion and which can be prevented from galling during repeated fastening and loosening without application of a compound grease. A solid lubricant coating which comprises a lubricating powder such as molybdenum disulfide and a resin binder is formed on the contact surface of at least one of the pin and the box. The solid lubricant coating has a hardness of 70-140 on the Rockwell M scale and an adhesive strength of at least 500 N/m as determined by the SAICAS (Surface And Interfacial Cutting Analysis System) method, and it exhibits excellent galling resistance even in the environment of high-temperature oil wells. Inclusion of ultraviolet screening fine particles such as titanium oxide fine particles in the solid lubricant coating increases the rust preventing properties of the threaded joint.
