微乳化切削液作用机制的研究

以自制的添加有磷酸三甲酚酯和含氮甘油硼酸酯极压抗磨剂的大豆油基微乳化切削液为研究对象,通过红外光谱和气相-质谱联用仪考察磨损试验前后微乳化切削液结构和成分的变化,从而推断出微乳化切削液发挥其功能的作用机制,为微乳化切削液作用机制的研究提供了一种新方法。该研究方法证实了微乳化切削液在金属表面起保护作用的主要是由极性较强的极压抗磨剂磷酸三甲酚酯和含氮甘油硼酸酯构成的吸附膜和摩擦化学反应膜。

Study on Acting Machanism of Microemulsion Cutting Fluid

The microemulsion cutting fluid based on bean oil which contains extreme pressure additives of tricresyl phosphate and glycerin borate ester containing nitrogen was prepared.The molecular configuration and component of microemulsion cutting fluid were assessed through FTIR(Fourier Transform Infrared Spectrography)and GC-MS(Gas Chromatography and Mass Spectrometry),and the acting mechanism of microemulsion cutting fluid was concluded,which provides a new method for the study of acting mechanism of microemulsion cutting fluid.The results prove that the adsorption films and friction chemical reaction films on the metal surface formed by high-polarity extreme pressure additives of tricresyl phosphate and glycerin borate ester containing nitrogen protect the wear of metal.
