摘要: The present invention addresses the problem of providing a cylinder liner or a cylinder bore, which can reduce not only friction on a sliding surface but also oil consumption. In a piston sliding direction of the cylinder bore, grooves of a second sliding region positioned on the side of crankcase have a higher groove area ratio at a depth of 0.3 µm than grooves of a first sliding region positioned on the side of combustion chamber, and the groove area ratio is in a specific range, whereby friction and oil consumption can be reduced.

摘要: An object of the present invention is to provide a cylinder liner for insert casting that can improve the joining strength between a cylinder liner and a cylinder block by reducing voids generated between the cylinder liner and the cylinder block.
The above-described problem can be solved when the molten metal running index YI defined by the following Formula (1) is from 2.2 to 14.5. Molten metal running index YI = area ratio S t % of top portions of protrusions × molten metal infiltration volume V mm 3 / surface area A mm 2 of cylinder liner base / average surface-to-surface distance P av between top portions of protrusions mm-

摘要: A novel method for producing a porous carbon material which makes it possible to easily produce a porous carbon material having a desired shape; and a spherical porous carbon material are provided. The method includes immersing a carbon-containing material 11 having a desired shape and composed of a compound, alloy or non-equilibrium alloy containing carbon in a metal bath 12, the metal bath having a solidification point that is lower than a melting point of the carbon-containing material 11, the metal bath being controlled to a lower temperature than a minimum value of a liquidus temperature within a compositional fluctuation range extending from the carbon-containing material 11 to carbon by decreasing the other non-carbon main components, to thereby selectively elute the other non-carbon main components into the metal bath 12 while maintaining an external shape of the carbon-containing material 11 to give a porous carbon material 13 having micro voids.

摘要: A method for producing a nano-composite metal member, by which a nano-composite metal member can be readily produced and the production cost can be reduced, and a method for joining phase-separated metal solids using the principle same as that of the former method are provided. A nano-composite metal member is obtained by bringing a solid metal body 11 comprising a first component into contact with a solid metal material 12 comprising a compound, an alloy or a non-equilibrium alloy that simultaneously contains a second component and a third component having a positive heat of mixing and a negative heat of mixing, respectively, relative to the first component, and then performing heat treatment at a predetermined temperature for a predetermined length of time, so as to cause interdiffusion between the first component and the third component.

摘要: Provided is a method for producing porous graphite capable of realizing higher durability, output and capacity, and porous graphite. A carbon member 13 having microvoids is obtained by a dealloying step for selectively eluting other non-carbon main components into a metal bath 12 by immersing a carbon-containing material 11, composed of a compound containing carbon or an alloy or non-equilibrium alloy, in the metal bath 12, wherein the metal bath 12 has a solidifying point lower than the melting point of the carbon-containing material 11, and is controlled to a temperature lower than the minimum value of a liquidus temperature within a composition fluctuation range extending from the carbon-containing material 11 to carbon by reducing the other non-carbon main components. The carbon member 13 obtained in the dealloying step is graphitized by heating in a graphitization step. The carbon member graphitized in the graphitization step is subjected to activation treatment by an activation step.
