... substitute for Pb-based dopants in MoS 2 -based solid lubricants and coatings with varying hBN contents (9.5, 11.5, 13.5, 15.5, and 17.5 wt.%) were applied to stainless steel substrates using a spray bonding technique. The friction and wear characteristics of the coatings were analyzed by using a ball...

...Shasha Dou; Kang Zhou; Haixu Qian; Haojie Shi; Jiansheng Xia A study on friction is necessary to improve the forming quality of stamped parts. It has been found that pulsed current can improve the forming properties of aluminum alloys, mainly in terms of Joule heat and electroplasticity. Thus...

An increase in the equivalent radius of curvature increases the film thickness and thermal rise in the contact zone as well as decreases the friction coefficient. Since the sleeve chain is one of the most commonly used mechanism...

... tribological properties compared to MSH-GO. The findings reveal that the oil sample containing 0.5 wt% MSH-C can effectively reduce wear volume by approximately 26.4% compared to fully formulated oil, with the friction coefficient decreased to ∼0.02. scanning electron microscopy (SEM), Raman, focused ion beam...
