TAC-COATED GRAPHITE MEMBER
To provide a novel TaC-coated graphite member having high corrosion resistance against corrosive gas, surface porosity, and high processability.SOLUTION: A TaC-coated graphite member 10 of this invention includes: a base material 20 consisting of isotropic graphite and a Tac coating film 30 formed on a surface of the base material 20. The TaC coating film 30 is formed of a laminate having a first layer 32 to an n-th layer 34 (n≥2) with relative density of Rto Rand thickness of tto t. The relative density Rof the first layer 32 formed on an interface side between the base material 20 and the TaC coating film 30 is larger than the relative density Rof the n-th layer 34 formed on a front side of the TaC coating film 30. The first layer 32 preferably has the relative density Rof 95% or more and the thickness tof 10 μm or more and 200 μm or less. The n-th layer 34 preferably has the relative density Rof 45% or more and 90% or less and the thickness tof 10 μm or more and 200 μm or less.SELECTED DRAWING: Figure 1
【課題】腐食性ガスに対する高い耐食性と、表面の多孔性と、易加工性とを兼ね備えた、新規なＴａＣ被覆黒鉛部材を提供すること。【解決手段】ＴａＣ被覆黒鉛部材１０は、等方性黒鉛からなる基材２０と、基材２０の表面に形成されたＴａＣ被膜３０とを備えている。ＴａＣ被膜３０は、相対密度がＲ1〜Ｒnであり、厚さがｔ1〜ｔnである第１層３２〜第ｎ層３４（ｎ≧２）の積層体からなる。基材２０とＴａＣ被膜３０との界面側に形成された第１層３２の相対密度Ｒ1は、ＴａＣ被膜３０の表面側に形成された第ｎ層３４の相対密度Ｒnより大きい。第１層３２は、相対密度Ｒ1が９５％以上であり、厚さｔ1が１０μｍ以上２００μｍ以下であるものが好ましい。第ｎ層３４は、相対密度Ｒnが４５％以上９０％以下であり、厚さｔnが１０μｍ以上２００μｍ以下であるものが好ましい。【選択図】図１
