CORROSIVITY MONITORING OF CRANKCASE LUBRICATING OILS FOR MARINE DIESEL ENGINES

For qualification of crankcase lubrication oils in ship diesel engines the total acid number, strong acid number and total base number were determined. It is shown that these numbers have a low degree of reproducibility. A more rapid and reliable method for assessing the corrosive properties of a used oil, using the conductivity relation of ultrathin cooper layers on an inert base material, was developed. Encouraging results were obtained.
