A problem is to provide a sliding member capable of easily improving friction characteristics, and a production method therefor. A solution is a sliding member 10, wherein a sliding portion 11 is formed of a metallic material, and the sliding member 10 has, on a surface of the sliding portion 11, a Cr-containing modified layer 12 formed by blasting a shot media containing Cr as a composition. The sliding member 10 slides under an environment of a lubricant containing Mo as an additive, in which active Cr exposed on the surface by sliding accelerates decomposition reaction of the additive contained in the lubricant to form a molybdenum disulfide-containing film having low friction on the surface of the sliding portion 11.

A sliding member includes: a base material; a coating layer formed on the base material and made of a resin composition including: a binder resin including polyamideimide; PTFE dispersed in the binder resin; and at least one of graphite and MoS.sub.2 dispersed in the binder resin; wherein a surface roughness of the coating layer after a sliding test is equal to or less than the surface roughness of the coating layer before the sliding test.

A sliding member with improved wear resistance. The sliding member including a base layer and a resin coating layer formed on the base layer; where the resin coating layer includes a polyamidimide resin as a binder; a solid lubricant; boehmite particles of greater than 0 volt and less than or equal to 1.0 volt; and inevitable impurities.

A plain bearing assembly (1) includes a rail and a carriage (20). The rail has a rail body (10) elongate in a longitudinal direction, and on one transverse side of there is a cylindrical guide portion (11). The carriage (20) includes a carriage body with a cylindrical passage (22) corresponding to the guide portion (11) to receive the guide portion (11). The inner side of the passage (22), with which, in an operating state of the plain bearing assembly, the carriage (20) rests slidingly in the longitudinal direction against the guide portion (11), is formed by a sliding element made from a sliding material. The sliding element is produced jointly with the carriage body as a one-piece carriage part made of plastics material.

Disclosed herein is a sliding member, such as a sliding bearing, including a resin overlay layer having improved conformability. The sliding member includes a bearing alloy layer and a resin overlay layer formed on the bearing alloy layer, wherein the resin overlay layer includes a solid lubricant phase, a binder resin phase, and a cushion phase, and an area ratio of the cushion phase is 0.5% or more but 5.0% or less.

A wear resistant coating is applied to the thrust surfaces and bore surfaces of a connecting rod. The wear resistant coating includes a polymer matrix, such as polyamide imide (PAI), solid lubricant, and hard particles including Fe.sub.2O.sub.3. The wear resistant coating is typically applied by spraying or rolling. The wear resistant coating adheres well to metal and provides lubrication. Thus, the wear resistant coating can reliably reduce wear, scuff, and seizure along the surfaces of the connecting rod as the piston reciprocates and crank shaft rotates during operation of the internal combustion engine. The likelihood of engine contamination caused by metal shavings from wear of the connecting rod is reduced, and the life of the connecting rod and engine is increased.

A rolling bearing has an outer diameter surface of the outer ring which is a fitting surface with a housing and the inner diameter surface of the inner ring, which is a fitting surface with a shaft. The outer diameter surface of the outer ring or the inner diameter surface of the inner ring is coated with a bonded film containing an organic binder, a solid lubricant powder such as molybdenum disulfide powder, and a friction/wear modifier such as antimony oxide powder. According to the rolling bearing, a creep resistance is kept excellent without causing increase in cost and size and being deformed and softened.

A bearing including a phthalonitrile-based polymer material. In one embodiment, the bearing is configured to withstand a temperature conditions of at least 600 F.

The present invention relates to hydrodynamic bearings, X-ray tubes, X-ray systems, and a method of manufacturing a hydrodynamic bearing for an X-ray tube. The rotor of a hydrodynamic bearing is supported, in steady-state operation, by the pressure of lubricant which is pumped through grooves in the rotor. When the rotor is speeding up or slowing down, the pumping force will not be sufficient to lift the rotor clear of a stationary bushing, and damage, caused by direct contact of the metal surfaces of the bearing, can occur. Providing special coatings on the bearing surfaces can ameliorate this effect.

The present invention pertains to a wear pad for a telescopic boom of a work machine, comprising a base part configured to be fixedly mounted to the telescopic boom, and a top layer part configured to provide a wear-resistant, low friction sliding surface. The top layer part is configured to be releasably mounted to the base part. The invention further pertains to a telescopic boom assembly for a work machine, comprising a first boom segment having at least one first wear pad assembly mounted to a free end of the first boom segment, and a second boom segment having at least one second wear pad assembly mounted to a sliding end of the second boom segment, wherein at least one of the wear pad assemblies comprise a wear pad having a base part and a top layer part configured to provide a wear-resistant, low friction sliding surface. The top layer part is configured to be releasably mounted to the base part. Further, the present invention pertains to a work machine comprising such telescopic boom assembly.
