Tribological Behaviour of Additive Free Calcium Stearate Greases

Two additive free calcium stearate greases have been developed for the requirements of lubrication in automotive components. Two compositions of calcium stearate greases have been prepared by adding 12% and 15% by weight calcium stearate soap in the 450-neutral base oil. Greases have been prepared u...
