On the influence of surfactant over friction properties of steel

Dry sliding friction behaviour of vanadis 23, orvar supreme substrates without surfactant shows its maximum value of 0.24 and 0.255 respectively, and found to be higher compared to oil medium. These values are of higher side due to the fact that during dry contact of both surfaces asperities rub against each other and this lead to detachment of material from one to another. The major part of the material transfer took place from the softer one due to the ploughing action.53
