摘要： A sliding member (1) includes a back-metal layer (2) and a sliding layer (3) on the back-metal layer (2), and the sliding layer (3) has a sliding surface (7). The sliding layer (3) includes a synthetic resin (4) and fibrous particles (5) dispersed in the synthetic resin (4). A volume ratio of the fibrous particles (5) in the sliding layer (3) is 1 to 15%, and the fibrous particles (5) are made of semi-graphite having a nano indenter hardness of 1000 to 5000 MPa. An average aspect ratio of the fibrous particles (5) is not less than 5, where an aspect ratio is defined as a ratio of a major axis to a minor axis of the fibrous particle (5) viewed from the sliding surface (7). An average grain size of the fibrous particles (5) in cross-sectional view perpendicular to the sliding surface (7) is 5 to 50 µm.

摘要： Provided is a sliding member (1) including: a back-metal layer (2) and a sliding layer (3) including a copper alloy (4). The back-metal layer includes a hypoeutectoid steel including 0.07 to 0.35 mass% of carbon and has a structure including a ferrite phase and pearlite. The back-metal layer has a high ferrite phase portion at a bonding surface (21) between the back-metal layer and the sliding layer. A volume ratio Pc and a volume ratio Ps satisfy Ps/Pc ≤ 0.4, where the volume ratio Pc is a volume ratio of pearlite in the structure at a center portion in a thickness direction of the back-metal layer, and the volume ratio Ps is a volume ratio of pearlite in the high ferrite phase portion.

摘要： Provided are a slide material in which the joining strength between a Bi-containing copper alloy layer and a substrate is improved, and a method for manufacturing the slide material. The slide material according to the present invention has a substrate and a copper alloy layer. The copper alloy layer comprises a copper alloy containing 4.0-25.0 mass% of Bi and has a structure in which Bi phases are scattered in a copper alloy structure. The contact area ratio of Bi phases of the copper alloy layer at the joining interface with the substrate is not more than 2.0%. The slide material is manufactured by casting a molten copper alloy onto a substrate and causing the copper alloy to solidify unidirectionally.

摘要： The technical field of this invention relates to an Al-based bearing alloy and a slide bearing that uses the Al-based bearing alloy. The technical problem of the invention is to provide an Al-based bearing alloy that exhibits high corrosion resistance and in which high strength is maintained for a long period of time even in a high temperature environment, as well as a slide bearing that uses the Al-based bearing alloy. As means for solving the problem, an Al-based bearing alloy (10) includes an Al matrix (11), and acicular compounds (12) which are needle-shaped that precipitate at a plurality of sites in a structure of the Al matrix, and that have a minor diameter and a major diameter.

摘要： The bearing apparatus 1 includes a crankshaft 3 having multiple journals 61, 62, main bearings 41, 42 supporting the crankshaft 3, and a bearing housing 8. The plurality of journals include a first journal 61 with a lubricating oil passage 63a and a second journal 62 without a lubricating oil passage. The first and second journals 61, 62 are supported by first and second main bearings 41, 42, respectively. The bearing housing 8 is constituted by an Alalloy upper housing 81 and an Fe-alloy lower housing 82. The depth D2 of the oil groove 42G of the upper half bearing 42U of the second main bearing 42 at least in a ±45° region ¸1 is equal to or smaller than a half of the depth D1 of the oil groove 41G of the upper half bearing 41U of the first main bearing 41 in the ±45° region ¸1.

摘要： A resin coating layer: having a shape line that indicates the shape of a surface and is divided by virtual straight lines parallel to the X axis; and setting an area of recessed sections that protrudes below the virtual straight lines and an area of protruding sections that protrudes above the virtual straight lines. A virtual straight line at a position at which the area totals for the area of recessed sections and the area of protruding sections are equal is defined as the average line for unevenness. Areas that protrude downwards from this average line for unevenness are defined as recessed sections and areas that protrude above this average line for unevenness are defined as protruding sections. The average area Sa for one recessed section is 4-120 µm 2 and the number M of recessed sections between two points having a distance of 1 mm therebetween is 3-20.
