摘要： A wear resistant sintered member exhibits superior wear resistance at the same level as those of the conventional materials without using a Co-based hard phase is provided. A first hard phase comprising Mo silicide particles dispersed in an Fe-based alloy matrix of the first hard phase and a second hard phase comprising a ferrite phase or a mixed phase of ferrite and austenite having a higher Cr concentration than the Fe-based alloy matrix surrounding a core consisting of Cr carbide particles, are diffused in an Fe-based alloy matrix, the Mo silicide particles are contained in the first hard phase in an amount of 3 to 25% by area, and the Cr carbide particles are contained in the second hard phase in an amount of 3 to 30% by area.

摘要： A valve train for an internal combustion engine is comprised of a lubricating oil, and a camshaft (1) which is made of an iron-based material and comprises a cam lobe (10) and a camshaft journal (20). The camshaft slidingly moves on a counterpart thereof through the lubricating oil. A hard carbon film is formed on at least one of a sliding portion of the camshaft and the counterpart made of an iron-based material. A hydrogen amount of the hard carbon film is 10 atomic percent or less.
