Lubricating agents are divided into different categories as manual lubricants, semi-automatic and automatic lubricants. Currently, there is an extensive range of solutions as central lubricants system which belong to class of semi-automatic and automatic lubrication. Essential lubrication systems encompass single element, double element and multi elements in addition to progressive systems which are basically used as a combination of three systems. Vahid Javan KouzegaranAnalytical …

Dry coating is a powerful tool to obtain desirable coating solutions. Tungsten disulfide, molybdenum disulfide, graphite, and PTFE are commonly combined with dry coating methods to achieve durable and self-lubricating coatings. This guide dives into the details of tungsten disulfide, molybdenum disulfide, graphite, and PTFE dry coatings, their application areas, weigh outs their advantage and disadvantages, and concludes which one is the best option.IntroductionCoating is without a d …

Tungsten disulfide (WS2) is a well-known super lubricant with almost zero friction that has a two-dimensional (2D) crystalline structure. WS2 has shown favorable tribological properties possessing wear-resistance and lubricating behaviors while having almost no friction. Vahid Javan KouzegaranAnalytical Chemist (Ph.D.) / Nanografi Nano TechnologyIntroductionThe so-called tribological characteristic of WS2 is as a result of its axial ratio with the numerical of at least 1.87 leadi …

Tungsten disulfide with the molecular formula of WS2 is a super lubricant (zero friction) and a crystalline structure. Tungsten sulfide exhibits excellent tribological properties meaning it is wear-resistant, lubricant and has no friction. The tribological property of WS2 originates from its axial ratio with the numerical of at least 1.87 in order to adopt a low friction coefficient. Tungsten sulfide has six nonbonding electrons that for a positive charge network on its surface layer a …
