“…The PTFE material + 15% fiberglass compared to the other materials analyzed has a lower wear rate. Figure 7 shows microscopic images [19] of the contact area in the sliding direction (from left to right) for the improved PTFE structure for different operating conditions [15,19] The results obtained experimentally correspond to many researchers found in specialized journals [1,2,7,8,[10][11][12][13][14]20].…”

The widespread use of thermoplastic polymeric materials in various industrial fields has shown considerable interest in understanding the frictional and wear behavior. Among these polymers, polytetrafluoroethylene, also called PTFE, is a high-performance plastic that offers high chemical and thermal resistance and low friction. Additives such as fiberglass, carbon and graphite fillers are added to PTFE to significantly increase thermal conductivity, stiffness and self-lubricating properties. The materials subjected to the experimental analysis were pure PTFE, PTFE + 15% fiberglass, PTFE + carbon-graphite which slipped, under conditions of dry friction, on a sample of non-alloy steel construction SR EN 10025 from 1994. The tests were performed on a pin-on-disc tribometer. The effect of loading and sliding speed on the tribological properties of the polymer / steel combination under dry slip conditions was investigated and the specific wear rate for the experimental conditions was evaluated. The tests were performed at loads of the pin of Fn1=1N, Fn2=3N, Fn3=5N and Fn4=10N and sliding speeds of 1=1m/s, 2=3m/s. The results obtained indicated that the coefficient of friction decreases with increasing load. The wear rate for the analyzed materials was between 10-13...10-15 m2/N, the fiberglass reinforced PTFE material having the lowest wear rate. The present paper, through a comparative analysis of the friction and wear behavior, highlights the effects that the ingredients introduced in the basic material have, under the action of the exploitation factors (loading, sliding speed).

“…An effective repairing method of steel surface is applying coatings with high toughness, anti-friction, and anti-wear to protect the steel from the attack of the service environment. [7][8][9][10] Therefore, there is an urgent need to develop the polymeric wear-resistant coating that can be used for surface restoration and has high toughness.…”

“…Steel has a fatal flaw of being vulnerable to wear and corrosion, and thus may fail to meet the safety requirements in the aggressive environments. An effective repairing method of steel surface is applying coatings with high toughness, anti‐friction, and anti‐wear to protect the steel from the attack of the service environment 7–10 . Therefore, there is an urgent need to develop the polymeric wear‐resistant coating that can be used for surface restoration and has high toughness.…”

Epoxy nanocomposite coatings play an important role in the wear protection of steel exposed in harsh service environments. How to improve the mechanical and wear resistance of coatings through filler addition is necessary to meet the industry application requirements. In the present paper, an epoxy-based nanocomposite coating was developed with addition of titanium dioxide (TiO 2 ), graphite, short carbon fibers (SCFs), and zinc sulfide (ZnS) for enhancement in mechanical, bonding to steel, and tribological performances.The reciprocating friction and wear performances of the coatings were investigated at room temperature and 100 C. The addition of nanometer sized TiO 2 and SCFs increased the tensile properties remarkably, while the addition of graphite and ZnS deteriorated the tensile properties. The fillers of graphite and ZnS had no obvious weakening effect on the interfacial shear strength between the coatings and steel, despite the solid lubrication of graphite and weak stiffness of ZnS. Compared with the epoxy sample, the wear rate of the coating filled with optimized filler combination (TTGCS5) was reduced by 19.5 times at room temperature and 25.9 times at 100 C. Addition of ZnS increased the wear resistance more pronounced compared to that of graphite at 100 C, which was attributed to formation of a compact, continuous and stable selflubricating transfer film on the coating surface. The optimized content of fillers was established for an epoxy coating to obtain the best friction rates of 0.51 and 0.56 (10 À4 mm 3 /[NÁm]) at 25 and 100 C, respectively.

“…They have indicated that they have an important influence on the friction and abrasion properties of the resulting transfer film layer. Bastiurea et al [12] prepared the graphene oxide and graphite filled polyester composites by using conventional melt-mixing methods to improve the tribological performance of polyester. Hassan et al [13] investigated the tribological properties of unfilled Low-Density Polyethylene (LDPE), Polyamide-12 (PA-12), and graphene nanoplatelets (GNPs) filled polymers by a pin-on-disc tester.…”
