Tribological investigation of cashew nut shell oil as lubricant additive

Abstract

The ecological and harmfulness issues of conservative lubricants as well as their increasing cost lead to converted interest in the growth of environmentally friendly oils as lubricants and manufacturing fluids. This investigation examines friction and wear behaviour of cashew nut shell methyl ester contaminated bio-lubricant using four-ball tribometer. The cashew nut shell methyl ester(CSME) was assorted with conservative lubricant in dissimilar fractions of 15% and 30% by volume. The investigation results shown that 30% addition of cashew nut shell methyl ester shows less coefficient of friction and wear scar diameter also reduced. the results show 30% addition of cashew nut shell methyl ester in bio-lubricant produces better presentation and antiwear features.
