摘要： PROBLEM TO BE SOLVED: To obtain an engine valve having reduced abrasion loss, and the combination of the engine valve and a valve seat. SOLUTION: In an engine valve equipped with a face part abutting a valve seat, and consisting of a base material of heat resisting steel; a nitriding layer including a sulfide is formed on at least the face part by the penetration of nitrogen and sulfur. The nitriding layer can be generally formed of an inner side nitriding layer having an Hv of 450 or more, having the main body of a nitride (Fe3 S and CrS), and also actually having no sulfide; and of a coexisting layer having an Hv of 350-450 wherein a sulfide (FeS) and a nitride coexist. The valve seat is constituted by dispersing a Co group hard particles, having an Hv of 450-950, of a Co- Mo- Cr- Si type in an Fe- C- Co base ground.

摘要： PROBLEM TO BE SOLVED: To improve heat resistance and durability and to suppress lowering of a friction factor by a method wherein a part to scrape off a substance adhered to the surface of a mating member is arranged in front in the relative movement direction of a friction plate body from a friction member on the opposite surface thereof. SOLUTION: The resilient material 4 is fixed in front of an inorganic friction material 3 in a relative rotation direction between the two side surfaces 1A of a core plate 1. The inner peripheral surface of a resilient member 4 is adhered on the outer peripheral surface of the friction material 3, and a protrusion amount from the side surface 1A of the resilient material 4 is higher than a protrusion amount of the friction material 3. When a wet friction plate A is moved to the left, the resilient material 4 makes contact with a metallic plate 22, an adhering substance, such as oil, on a side surface 22A is scraped off. Thereafter, the resilient material 4 is brought into contact with the side surface 22A, torque is transmitted to the metallic plate 22 through frictional resistance, and a clutch drum 5 is rotated in a driven state. This constitution provides heat resistance and durability of the friction material 3, prevents the occurrence of deterioration due to a friction heat, suppresses lowering of the friction factor of the surface of the friction material 3, and maintains a stable torque transmission function for a long period.

摘要： PURPOSE:To show both characteristics of a martensitic phase and a ferritic phase by impregnating copper into a specified sintered stainless steel. CONSTITUTION:For example, the powder of stainless steel equivalent to SUS430L is used for the formation of a ferritic phase and the powder of stainless steel equivalent to SUS 410L is used for the formation of a martensitic phase to form sintered stainless steel constituted of 20 to 50vol.% martensitic phase and the balance ferritic phase. This is brought into contact with a sintered body, e.g. of copper or a copper allay, and impregnation is executed at 900 to 1200 deg.C for 30 to 90min in a reducing atmosphere. The martensitic phase is incorporated with, by weight, 10 to 15% Cr and the ferritic phase with 16 to 30% Cr. The copper alloy is incorporated with at least one kind among Pb, Zn, Sn, Al and Ni. Thus, it can suitably used for the material requiring wear resistance or the like in a high temp. oxidation atmosphere.
