[0002] At present, the U.S. military has generally used anti-corrosion synthetic aviation lubricating oil, high-temperature stable type is used in special cases, and standard synthetic aviation lubricating oil is used only in emergency situations, while our country is still using standard synthetic aviation lubricating oil. , which is very different from that of the United States. The development of anti-corrosion synthetic aviation lubricants is still in a blank stage. To develop anti-corrosion synthetic aviation lubricants, it is necessary to establish a set of simulation evaluation methods and test devices for bearing corrosion to evaluate anti-corrosion synthetic aviation lubricants. The performance of the oil is good or bad, to assist the development of oil products

Abstract
The invention relates to method and device for estimating degree of corroding a bearing by corrosion-preventing synthesized aviation lubricating oil, belonging to the technical field of research and development of corrosion-preventing synthesized aviation lubricating oil. The device comprises a low-temperature box, a compressor unit, a high-temperature box, a moisture box protecting chamber and an electric cabinet, wherein the compressor unit is connected with the low-temperature box through a condensing pipe, and the low-temperature box is used for carrying out a low-temperature test; the high-temperature box is used for carrying out a high-temperature test; the moisture box protecting chamber is used for placing a moisture box; the electric cabinet is a core of the device, controls normal work of all parts and ensures that the temperature of the low-temperature box is constant in 5+ / -1 DEG C and the temperature in the high-temperature is constant in 40+ / -1 DEG C; the timing and alarm prompting functions can be automatically completed, and the test condition in the low-temperature box can be observed through an observation window. The determination of the method and the successful research of the device thoroughly solve the problem of estimation of the property of the corrosion-preventing synthesized aviation lubricating oil, and play an important role of researching the corrosion-preventing synthesized aviation lubricating oil.
