Effect of iron and copper on the thermal oxidation stability of synthetic hydrocarbon aviation lubricating oil

The effect of Cu and Fe sheets on the thermocatalytic oxidation of synthetic hydrocarbon lubricating oils at high temperatures were investigated using various analytic techniques. The fast oxidation rate, low thermal stability, more composition and high relative content of compounds was observed by...
