Influence of Li Grease Thickener Types on Film Thicknesses Formed between Smooth and Dented Surfaces

Tribology Online, 2017
The lubricant film thickness behaviors of lithium (Li) thickener type greases and their base oil were investigated for the contact between a glass disk and a smooth/dented steel ball using an optical interferometry. The main focus is to understand grease

The application of biochar as an alternative to graphite in mineral greases – Tribological and rheological property studies

Industrial Crops and Products
This study aims to investigate the possibility of replacing a critical raw material - graphite - with an ecological biochar material used as a functional additive to mineral greases thickened with lithium stearate. Biochar is obtained by pyrolysing wheat

Tribology of 2-Mercaptobenzothiazole in Lithium Complex Grease

, 2011
There has been no much difference in usage pattern of EP/antiwear additive chemistry of additives in greases and other lubricants like cutting fluids and gear oils. These additives perform very well in some greases but not able to perform up to desired level in other applications. Due to high active sulfur content, they need supplementary additive with
