Analysis of antiscoring properties of hydraulic oils

The paper discusses findings of the experimental study of the tribological characteristics of hydraulic oils HVLP-46, MGE-46d, MGE-46l, VO, ZF-46, and HLP-46. A technique is developed for studying the antiscoring properties of hydraulic oils based on measurements of contact resistance for the shaft-partial insert geometry (multiple contact). It is shown that contact resistance is a more sensitive parameter compared to the coefficient of friction.
