Table 2 shows the results of sliding tests conducted at room temperature and in a dry state at 700°C. 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.
