Analysis of the Thermomechanical Stability of Greases Made with Different Types of Highly Alkaline Detergent Thickeners

Results are given for an experimental study of the thermomechanical stability of greases with thickeners derived from three types of highly alkaline detergents: (calcium sulfonates, alkylsalicylates, and alkylphenolates) using a ball bearing stand. The salicylate and phenolate lubricants proved rather resistant to oxidation. The composition of the dispersion medium also had a great effect in the case of the salicylates.
