采用球-盘摩擦磨损试验机研究了稻壳与酚醛树脂混合物在900 ° C N2气氛下碳化制备的稻壳陶瓷与高碳铬钢（JIS SUJ2）、奥氏体不锈钢（JIS SUS304）和氧化铝（Al2O3）在干摩擦条件下的摩擦磨损性能。结果表明，RH陶瓷与SUJ2和SUS304摩擦副的摩擦系数分别为0.05-0.08和0.06-0.11，与Al_2O_3摩擦副的摩擦系数较高，为0.14-0.23。SUJ2的比磨损率最低，低于10 - 9mm2/N，而SUS304和Al2O3的比磨损率大多在10 - 9~10 - 8mm2/N之间。用光学显微镜观察了对应件的磨损表面，并使用横截面透射电子显微镜、能量色散X射线光谱仪和电子衍射仪进行了分析。结果表明，RH陶瓷的摩擦学性能与其在摩擦副表面形成的由非晶SiO2和碳颗粒组成的转移膜密切相关。在SUJ2球上容易形成转印膜，而对于SUS 304，膜的存在受到滑动条件的影响。此外，在Al2O3对应物上不能检测到转印膜的形成。
The friction and wear behaviors of rice husk (RH) ceramics, prepared by carbonizing the mixture of rice husk and phenol resin at 900 °C in N2gas environment, sliding against high carbon chromium steel (JIS SUJ2), austenitic stainless steel (JIS SUS304), and Al2O3under dry condition were investigated using a ball-on-disk tribometer. The test results show that the friction coefficient of RH ceramics takes very low values 0.05–0.08 and 0.06–0.11 sliding against SUJ2 and SUS304, respectively, and much higher values around 0.14–0.23 against Al2O3. It was also shown that SUJ2 provides the lowest specific wear rate values below 10−9mm2/N, while, those of SUS304 and Al2O3mostly stayed between 10−9to 10−8mm2/N range. The worn surfaces of counterparts were observed with optical microscopy and analyzed using cross-sectional transmission electron microscopy with energy dispersive X-ray spectroscopy and electron diffraction. It was suggested that the tribological behaviors of RH ceramics are closely related with the formation of a transferred film, consisted of amorphous silica and carbon particles, on a counterpart surface. The transferred film was formed readily on SUJ2 balls, whereas for SUS304 the presence of the film was subject of the sliding conditions. Moreover, formation of the transferred film could not be detected on Al2O3counterparts.
