Influence of Natural Serpentine on Tribological Performance of Phosphate Bonded Solid Coatings

Zhengchao Xi et al.

Summary: Natural serpentine powders were incorporated into phosphate-bonded solid coatings to enhance anti-wear performance. Through experiments, it was found that the optimal incorporation of natural serpentine in phosphate coatings was 10 wt.%, resulting in significantly elevated anti-wear performance. Furthermore, under harsher friction conditions, the strengthening effect of natural serpentine on the tribological performance of phosphate composite coatings was further stimulated.

A review on tribology of polymer composite coatings

Yilong Ren et al.

Summary: This study compares the heat resistance, tribological and mechanical properties of polymer matrices and functional fillers in composite coatings, and discusses the mechanisms of friction reduction and mechanical property enhancement. Methods for improving the adhesion properties between the coating and substrate are also explored. Design strategies for high-performance polymer composite coating systems and the current limitations in polymer composite coating research are proposed.

Black phosphorus quantum dots: A new-type of water-based high-efficiency lubricant additive

Weiwei Tang et al.

Summary: Black phosphorus quantum dots (BPQDs) used as water-based lubricant additives showed remarkable friction reduction and anti-wear properties even at ultra-low concentrations. The additives also demonstrated a relatively long lifetime at high loads and outperformed BP due to their small particle size, good dispersion stability, and high reactivity at frictional surfaces. The formation of a robust tribochemical film on the rubbing surface lubricated with BPQDs further indicated their excellent tribological performance.

Synthesis of hexadecylamine modified carbon dots and their friction-reducing and anti-wear performance in polyalphaolefin

Zhu Liang et al.

Summary: Hexadecylamine modified carbon dots (CDs-HA) synthesized by pyrolyzing citric acid in HA exhibit excellent friction-reducing and anti-wear properties when used as lubricant additives of polyalphaolefin (PAO4). Both the concentration and load have significant influences on the tribological performance of CDs-HA, with higher loads leading to decreased friction performance but relatively stable anti-wear properties. The results indicate that CDs-HA participate in boundary lubrication film formation on rubbing surfaces and have rolling, polishing, and mending effects, contributing to their outstanding performance.

Tribocatalytically-activated formation of protective friction and wear reducing carbon coatings from alkane environment

Asghar Shirani et al.

Summary: The study reveals the anti-wear capability of metal nitride-copper nanocomposite coatings in liquid hydrocarbon environments. The formation of carbon-based protective films at the sliding interface contributes to the significant reduction of wear. Analysis of tribological characteristics under different conditions provides insights into the tribocatalysis mechanism facilitating the formation of zero-wear coatings.

Fluid-like carbon dots-based ionic fluid towards high efficient lubricant nanoadditive of polyethylene glycol

Tao Cai et al.

Summary: Solid polyelectrolyte grafted carbon dots were synthesized and used to produce carbon dots-based ionic fluid. The results showed significant improvement in friction-reducing and wear-resistance performance in polyethylene glycol. Due to the excellent dispersion, the ionic fluid could form a continuous carbon-rich oil-film at the frictional interface, enhancing friction-reducing and wear-resistance abilities effectively.

Hamed Bahramnia et al.

Summary: This study introduced a novel approach to fabricate hybrid polymer nanocomposite coatings, demonstrating that the addition of an appropriate amount of nanoparticles can improve the coating's performance in terms of hardness and wear resistance. However, excessive nanoparticles negatively impact the samples' pull off strength, hardness, and modulus of elasticity.

Characterization and Tribological Performance of Polyethersulfone/PTFE Compound Filled with Na-Montmorillonite

Zhen Zuo et al.

Summary: The abrasion resistance of PES/PTFE-based composites was effectively improved by introducing NaMMT as a reinforcing filler, attributing to the load bearing of NaMMT on the worn surface. The polymer sample with 20 wt% NaMMT exhibited the best anti-wear performance, with its densification worn morphology contributing to the improvement. Additionally, the introduction of NaMMT disrupted the self-lubricating property of PTFE transfer films, resulting in a slightly larger friction coefficient for NaMMT/PES/PTFE compounds compared to pure PTFE and PES/PTFE compounds.
