In Table 2, the comparative materials are those using commercially available polymeric materials, solid lubricant-containing metal sintered materials, and ceramics, and the counterpart materials are bearing blade J.
IS-8UJ2 was used. Comparative polymer materials and solid lubricant-containing sintered metal materials cannot be used at temperatures above 200° C. because they become unstable due to heat, so tests were conducted only at room temperature. The test was conducted for 10 hours at a surface pressure of 5 kgf/- using bearing steel JISSU and 1T2 as the mating material.

Can not. In addition, Ceremix A403 (alumina)
Although the amount of wear is small, the coefficient of friction is high at about 0.5. Compared to these comparative materials, the sliding member of the present invention has a lower wear amount and a lower coefficient of friction both at room temperature and high temperature, and stably exhibits excellent sliding properties. Furthermore, the sliding member of the present invention can of course be used not only under dry friction conditions but also under oil-based sliding conditions [Effects of the Invention] The sliding member of the present invention exhibits stable and excellent sliding performance from room temperature to high temperature Since it exhibits dynamic characteristics, it can be used as a sliding member for various purposes. % [, Since it has sliding properties at high temperatures that other materials do not have, it can be applied to boiler bearings and valves of ultra-high temperature and high pressure turbines, and its range of use is wide.
