Antiwear Properties of Composite Greases “Litol-24–Magnesium Hydrosilicate Particles”

Addition of magnesium hydrosilicate particles (talcum and serpentinite) with sizes of 1–30 μm to Litol-24 ARGO grease reduces surface wear of balls made of steel grade ShKh15. Between friction surfaces, local metal–mineral composite films are generated with high microhardness which reduce wear of fr...

Zusammenfassung:Addition of magnesium hydrosilicate particles (talcum and serpentinite) with sizes of 1–30 μm to Litol-24 ARGO grease reduces surface wear of balls made of steel grade ShKh15. Between friction surfaces, local metal–mineral composite films are generated with high microhardness which reduce wear of friction elements. Forsterite, wollastanite, and some other modifications serve as minerals; they are generated owing to solidification of talcum and serpentinite under high pressures and temperatures.
