Calcium sulfonate complex greases (CSCG) have proven to be a sustainable alternative to
lithium complex greases, which still require appropriate additives to deliver lubrication …

In this study, copper (II) oxide, titanium dioxide and yttrium (III) oxide nanoparticles were
added to Group III-type base oil formulated with overbased calcium sulfonate. The …

Improving the lubrication condition of oil-starved rolling bearings is a proven method to
improve their reliability and service life. In this study, a composite surface texture was …

A novel self-transport biomimetic composite texture on the guiding surface of thrust ball
bearings was presented. The distribution and morphology of the grease fingers were …

The prolonged operation of the motor in the all-electric aircraft can cause the fragmentation
and shortening of grease thickener fibers, ultimately resulting in the lubricating grease …

Nano additives play an important role in improving the lubricating properties and enhancing
the bearing capacity of lubricants. However, traditional nano-additives contain harmful …

In order to further extend the service life of calcium sulfonate complex–polyurea grease
(CSCPG) while ensuring its tribological performance, this article starts with the production of …

In this study, polydopamine and silver-modified graphene oxide (Ag/PGO) were prepared
using a one-step method, and the effects of Ag/PGO as a lubricating oil additive on the …

Polyurea complex thickener was introduced into calcium sulfonate complex grease (CSCG)
to prepare a new type of grease. The microstructure, rheological properties, and tribological …
