在万能摩擦试验机上采用钢/镍钛合金、钢/铝和钢/钢摩擦副进行乙二醇的摩擦化学反应研究;采用紫外光谱(UV)、傅立叶变换红外光谱(FT-IR)和核磁共振光谱(^1HNMR)对摩擦产物进行分析。结果表明:乙二醇在钢/镍钛合金摩擦副表面发生摩擦化学反应,生成含有碳碳双键的化合物,而在钢/铝及钢/钢摩擦副表面不发生摩擦化学变化;在试验条件中,速度是影响摩擦化学反应的主要因素,而载荷对摩擦化学反应影响较小。
The tribological tests of glycol on Nitinol-Steel, Al-Steel and Steel-Steel rubbing surfaces were studied using universal friction and wear tester. The wear products were characterized by UV, FT-IR, and nuclear magnetic resonance (NMR)spectroscopy. The results show that tribochemical reaction occurs for glycol on Nitinol-Steel rubbing surface and compounds containing carbon-carbon double bonds produce in the process of tribological tests, however, it does not occurs tribochemical reaction on Al-Steel and Steel-Steel rubbing surfaces. Speed is the most factors influence tribochemical reaction under test conditions, and load has a lesser impact on tribochemical reaction.
