Abstract: A series of lubricating oils containing different mass fractions of anticorrosion additive were prepared.Static adsorbent experiments using simulating axletree balls in those lubricating oil samples were performed.The absorbency of lubricating oil before and after the adsorbent experiments were measured with UV spectrograph,and the adsorbent quantity of anticorrosion additive was calculated through the absorbency difference of the lubricating oil before and after the adsorbent experiments to characterize the adsorption effect of anticorrosion additive.The temperature and humidity of ocean environment were simulated through a self-made equipment,and the axletree balls with which adsorbent experiments were performed in the lubricating oil were put into the equipment to do the corrosion experiments.Data processing on the laboratory findings was made according to the hierarchical corrosion grade criterion,and the anticorrosion ability of the lubricating oil was estimated on the basis of axletree balls’ corrosion grade.The relationship between adsorbent quantity of anticorrosion additive on the axletree balls surface and anticorrosion ability of lubricating oil indicated that the anticorrosion ability of lubricating oil was determined by the adsorption effect of anticorrosion additive.

Key words: anticorrosion additive, UV spectrum, adsorption effect, anticorrosion ability, lubricating oil
