Abstract: An investigation was made on the water solubilization by oil-soluble rust inhibitors in lubricating oil using phase diagram technigue. Quantity of water solubilization by rust inhibitors was calculated based on the phase digram. It has been established and elucidated from laboratory test that water solubilization by oil-soluble rust inhibitors is a mechanism of rust preventive oil action.

摘要： 应用相图测定法研究油溶性防锈剂润滑油溶液对水的增溶作用。在相图测定的基础上,计算出防锈剂对水的增溶度。通过实验,阐述并证明了油溶性防锈剂对水的增溶作用是一条防锈作用机理。
