Tribological investigations of pure nanolamellar MoS2, composite Cu–MoS2 lubricants and greases were carried out by “ball-on-disk” Personal computer-Operated Significant Temperature Tribometer TXT-S-AH0000, CSEM. The don scar was explored over a noncontact profilometer Micro Measure 3D Station, STIL. All exams had been carried out employing a 30 mm diameter medium-carbon steel disks as the friction human body, along with a vanadium-cobalt ball of diameter 3 mm was used as the counterface. The exams were being run utilizing a load of five N and sliding speed of 5 cm/s, with keep track of diameter 3 mm, duration of checks was 30 min. The indicate Speak to pressure was 0.fifty six N/mm2. Soon after friction tests surface area of use scars have been analyzed employing an atomic force microscope Ntegra Aura (NT-MDT, Russia).
Selective transfer phenomenon in lubricated sliding surfaces with copper and its alloy coatings created by electro-pulse spraying
