Abstract

The effect of dispersed particles of lamellar molybdenum, tungsten and vanadium oxides on the lubrication properties of mineral oil was investigated. It is shown that in the presence of particles of hexagonal molybdenum oxide the coefficient of friction falls two-fold (from 0.08 to 0.04) exhibiting further decrease under high mechanical load, i. e. molybdenum oxide behaves as an adaptive lubricant. The intercalation of benzotriazole into molybdenum oxide ensures additional reduction of mechanical wearing due to suppressing the tribocorrosion.

摩擦化学用途的钼、钨、钒氧化物苯并三唑插层分散体的合成
研究了层状钼、钨、钒氧化物分散颗粒对矿物油润滑性能的影响。结果表明,在六方氧化钼颗粒存在的情况下,摩擦系数下降了两倍(从0.08降至0.04),并且在高机械载荷下进一步降低,即氧化钼具有自适应润滑剂的作用。由于抑制摩擦腐蚀,苯并三唑嵌入到氧化钼中确保额外减少机械磨损。
