Study of ferromagnetic nanoparticles effect on tribotechnical lubricating characteristics

The research objective is to study tribological properties of the lubricating compositions based on the Castrol oil and ZIATIM -201 plastic lubricant modified by the ferromagnetic nanosuspension. A qualitative X-ray phase analysis by the diffractometry method is conducted on the ARL X´TRA computeriz...
