木陶瓷是以木材或木质材料浸渍酚醛树脂，在真空炉中高温炭化而制得的新型多孔碳材料。从工程材料和生态材料的角度来看，木陶瓷具有坚硬、强度高、多孔结构、密度低、取自自然资源、不造成环境污染、制造成本低廉等优越特性。本文描述了木陶瓷与几种材料滑动接触时的基本摩擦特性。将中密度纤维板（MDF）和山毛榉制成的木陶瓷浸渍酚醛树脂并在800℃和2000℃真空炉中碳化，使用往复摩擦装置与氧化铝、氮化硅、轴承钢和金刚石进行摩擦。实验在未润滑的空气中、浸有基础油和水中、在几种正常载荷和滑动速度下进行。获得以下主要结果：（1）在所有三种润滑条件下，摩擦系数约为0.15； (2)随着法向载荷的增加，摩擦系数略有减小，然后保持不变； (3)摩擦系数不受滑动速度的影响； (4)木陶瓷具有良好的自润滑性。
Woodceramics are new porous carbon materials obtained from wood or woody materials impregnated with phenol resin, and carbonized in a vacuum furnace at high temperature. Woodceramics have several superior characteristics from the viewpoints of engineering materials and ecological materials: they are hard and strong, have porous structure and low density, are made from natural resources, do not cause environmental pollution, and are cheap to manufacture. This paper describes the fundamental friction properties of Woodceramics in sliding contact with several materials. Woodceramics made of medium density fiberboard (MDF) and beech impregnated with phenol resin and carbonized in a vacuum furnace at 800°C and 2000°C were rubbed against alumina, silicon nitride, bearing steel and diamond by using a reciprocating friction apparatus. Experiments were carried out unlubricated in air, impregnated with base oil and in water, at several normal loads and sliding velocities. The following principal results were obtained: (1) The friction coefficient is around 0.15, under all three lubrication conditions; (2) The friction coefficient slightly decreases and then stays constant with increasing normal load; (3) The friction coefficient is not affected by sliding velocity; (4) Woodceramics have a good self-lubricity.
