    摘要: Systems and methods provide for wear reduction in a combustion system of a gas turbine. A system for wear reduction includes: at least one substantially H-shaped block, the substantially H-shaped block being configured to secure a transition piece of a gas turbine combustor to a support piece; a first insert including a tungsten carbide in a metal matrix, the metal matrix being selected from a group including cobalt and nickel; and a brazing material which is used in brazing the first insert to the at least one substantially H-shaped block in at least one location on an interior wear surface of the at least one substantially H-shaped block.

    摘要: A sintered cubic boron nitride tool can perform stable machining without causing any defect for a long lifetime even under a high-load cutting condition and a high-efficiency cutting condition. The sintered cubic boron nitride tool is such that: assuming a reference length longer than five times an average particle size of cubic boron nitride is S, when a total length of profile curves of cubic boron nitride included in the reference length S of the chamfer honing surface is LCC, when a total length of profile curves of the binder phase included in the reference length S of the chamfer honing surface is LCB, and a ratio of LCC to LCB is PC(PC=LCC/LCB), and when a total length of profile curves of cubic boron nitride included in the reference length S of the round honing surface is LRC, a total length of profile curves of the binder phase included in the reference length S of the round honing surface is LRB, and a ratio of LRC to LRB is PR(PR=LRC/LRB), then, a ratio of PR to PC (PR/PC) satisfies the relation of 1.2≦PR/PC≦8.0.
