  • Patent number: 9849511
    Abstract: A Cu-based sintered sliding member that can be used under high-load conditions. The sliding member is age-hardened, including 5 to 30 mass % Ni, 5 to 20 mass % Sn, 0.1 to 1.2 mass % P, and the rest including Cu and unavoidable impurities. In the sliding member, an alloy phase containing higher concentrations of Ni, P and Sn than their average concentrations in the whole part of the sliding member, is allowed to be present in a grain boundary of a metallic texture, thereby achieving excellent wear resistance. Hence, without needing expensive hard particles, there can be obtained, at low cost, a Cu-based sintered sliding member usable under high-load conditions. Even more excellent wear resistance is achieved by containing 0.3 to 10 mass % of at least one solid lubricant selected from among graphite, graphite fluoride, molybdenum disulfide, tungsten disulfide, boron nitride, calcium fluoride, talc and magnesium silicate mineral powders.

  • Patent number: 8431231
    Abstract: The present invention provides a titanium material having high-temperature oxidation resistance at high temperatures above 800° C. and an exhaust pipe made of this titanium material for an engine. A titanium alloy contains 0.15 to 2% by mass Si, has an Al content below 0.30% by mass, and has equiaxial structure having a mean grain size of 15 ?m or above. The high-temperature oxidation resistance of the titanium alloy at high temperatures above 800° C., such as 850° C., is improved by means including adding Nb, Mo and Cr in combination with Si to the titanium alloy, forming equiaxial structure of coarse grains, creating acicular structure, Si-enrichment of a surface layer of the titanium alloy, and reducing impurities including copper, oxygen and carbon contained in the titanium alloy.
