CERAMIC STRUCTURE FOR FAUCET DEVICE, SLIDE VALVE FOR FAUCET DEVICE AND CARTRIDGE FOR FAUCET DEVICE
PROBLEM TO BE SOLVED: To suppress stress concentration to irregularities formed on a surface of a slide layer due to frictional force, and suppress occurrence of fine cracking in a ceramic structure for a faucet device due to the frictional force.SOLUTION: A ceramic structure for a faucet device includes a ceramic substrate, and a slide layer formed on the surface of the substrate. The substrate is formed of dense ceramic with no pore on its surface. The slide layer is formed of diamond-like carbon. A frictional coefficient of the surface of the slide layer is smaller than a frictional coefficient of the surface of the substrate.SELECTED DRAWING: Figure 3
【課題】摺動層の表面に形成された凹凸への摩擦力由来の応力集中が抑制され、摩擦力による水栓装置用セラミック構造体の微小なひび割れの発生を抑制する。【解決手段】水栓装置用セラミック構造体であって、セラミック製の基体と、該基体の表面に形成された摺動層とを備え、前記基体が、表面に気孔を有さない緻密質のセラミックで形成され、前記摺動層が、ダイヤモンドライクカーボンで形成され、前記摺動層の表面の摩擦係数が、前記基体の表面の摩擦係数より小さい。【選択図】図３
