Nano Diesel Soot Particles Reduce Wear and Friction Performance Using an Oil Additive on a Laser Textured Surface

Abstract

Tribological properties of nano diesel soot (DS) as an additive were investigated. Textures in linear radiating arrays were prepared on the surface of a spring-steel plate by laser radiation. The texture densities were 19.6%, 22.1%, and 44.2%, and the depth was 30 µm. The results indicated that the textured surface was interacted with additive favorably to improve its tribological performance. Friction coefficients and wear rates of textured surfaces with additive in oil were generally much lower compared to the original surface without additive. The higher area density of the textured surface with the additive in oil had the lowest friction coefficient, as low as 0.12, and also the minimum wear rate, as low as 1 × 10 3 µm/N·m in 100 • C, to be achievable. Such results can be attributed to the formation of the tribo-film and the storage function of the micro-dimple.

Sustainable Kilogram-Scale Conversion of Tire Pyrolysis Waste into Nanosized Onion-like Carbons with Extraordinary Lubricant-Additive Properties

“…The importance of optimal concentration of additives for securing better wear characteristics has also been reported . C-soot samples derived from bio-diesel and diesel vehicle exhausts have also helped reduce wear when used as an additive in lubricating media. , …”

“…In this work, OLCs converted from TPW have proven to be an extraordinary lubricant additive, facilitating an exceptional reduction in friction and wear. While all the earlier reports of using carbon materials with onion-like morphology have shown substantial improvement in the tribological performance as solid lubricants and of various lubricating media under optimized conditions, ,,,− the material synthesis processes in these reports limit the large-scale application of OLC as potential lubrication-enhancing fillers. In this study, a single-step heat treatment of TPW was done on a kilogram scale.…”

“…53 C-soot samples derived from bio-diesel and diesel vehicle exhausts have also helped reduce wear when used as an additive in lubricating media. 35,37 From the above-presented experimental observations and related discussion, adding the TPW particles and OLC to BO improved the rheological properties of BO and also effectively helped in reducing friction and wear. The mechanism through which TPW and OLCs minimize the friction and wear is vital and needs to be further understood for effective utilization of such nanomaterials as additives in lubricants.…”

“…Lubricants can form a stabilized film of lubrication on the surface of the mechanical part and prevent direct contact with the microconvexity of the metal surface [7]. Additives, which can tune the tribological behavior of the oil-based lubricant, are a type of important materials that help develop different lubricants for different working scenarios [8,9]. Therefore, there is a need to explore high-performance lubricant additives for meeting the growing lubrication requirements resulting from the development of mechanical society.…”
