Elastomeric polymers such as high‐density polyethylene, have a variety of desirable features, that have supplanted traditional materials. However, high‐density polyethylene (HDPE) shows inadequate wear resistance, which limits its use for industrial applications, particularly in low‐load‐bearing applications such as flexible energy harvesting devices and sensors. The current work is engrossed in investigating the influence of hybrid reinforcements CaCO3 particles and bentonite nano clay as secondary reinforcements in high‐density polyethylene (HDPE)‐based composites on the wear and friction properties. The reinforcements were melt compounded with HDPE using a Brabender mixer and sampled using an injection molding machine. The wear test (ASTM G‐99‐04) was performed by a pin‐on‐disk tribo‐tester. In comparison to a base matrix, the synthesized hybrid composite achieved the maximum improvement in wear rate of 93%. The results revealed that there is a significant improvement in wear resistance. Morphological analysis revealed that due to the encapsulation and compatibilization effect of bentonite nano clay the hybrid composite exhibited improved wear performance. The results signify the synergistic effect of filler particles resulted in sufficient bonding for stress transfer due to the encapsulation of CaCO3 by nano clay. The wear mechanism observed optically was abrasion, fatigue, and adhesion wear that changed with the change in the weight percent of nanoparticles. Finally, the prepared composite with enhanced tribological properties such as low wear rate, low friction coefficient, and enhanced morphology can be used in low load‐bearing wear applications such as turbo nanogenerators and piezo nanogenerators.Highlights Bentonite nano clay and CaCO3 dispersed homogeneously in HDPE matrix. Wear resistance of HDPE increases by reinforcing particles (nano‐clay and CaCO3). Micro‐cutting, deformations, and particle husks were the possible wear mechanism. Encapsulation effects the hybrid composite to exhibit improved wear performance.

“…32 Since the thermoplastic resins (polytetrafluoroethylene, PVDF, and PDMS) suffer from poor wear resistance, the comparison of the wear rate is conducted among EP, PI, GO/ CNTs/PI, (TPE-R)-PHTs, and (TPE-Q)-PHTs. 33,34 The wear rate of polymers is given in Figure 5d. The specific wear rates of the (TPE-R)-PHT film and (TPE-Q)-PHT film were 10.1 × 10 −5 and 7.87 × 10 −5 mm 3 /N m lower than those of PI, GO/ CNTs/PI, and EP.…”

The isomeric poly(hexahydrotriazine)s (PHTs) were prepared, based on their hemiaminal dynamic covalent networks via a facile method at 50 °C, through 1,3-bis(4-aminophenoxy)-benzene (TPE-R) and 1,4-bis(4-aminophenoxy)-benzene (TPE-Q) with formaldehyde. The influence of chain isomerism on thermal stability, mechanical properties, tribological properties, and the degradation rate of PHTs was investigated. The advantage of (TPE-Q)-PHTs compared with that of (TPE-R)-PHTs is that they possessed a higher glass transition temperature (T g) of 187 °C, a higher Yang’s modulus of 10.7 GPa, and rapid degradation rate. Additionally, the (TPE-Q)-PHTs exhibited outstanding self-lubricating performance as compared to (TPE-Q)-PHTs because the para-connecting isomers showed lower surface energy, lower surface roughness, and higher hardness that effectively weakened the bonding force between friction pairs. Overall, the study of PHTs facilitates their practical application of energy conservation and environmental protection in the tribological industry.

Due to the good properties related to wear resistance and vibration absorption capacity, the polymeric materials successfully replace the metallic materials. These are used in the production of sliding motion couples. Rubbing couples whose materials are polymer / steel based are of particular interest for technical use. In order to operate any mechanical system with sliding motion at optimum parameters, the indication of tribological characteristics for the materials of the frictional coupling is a convenient means of characterizing faster the tribological behavior, when the working conditions are modified. In this paper it is analyzed by the help of an experimental study, the factors affecting the wear of a coupling of polymer material/steel. Materials subjected to tribological analysis are polymeric materials, such as polyamide (PA) and polytetrafluoroethylene (PTFE) in contact with a metallic material (steel). The connection between the friction coefficient and the operating parameters (load, speed) and the rate of wear of these materials under experimental conditions will be established. Testing of the two materials was made on a pine stand on disc. The tribological tests were performed varying load and speed for a given length of friction, traveled pine. The wear of the two materials tested for the experimental conditions was measured. The experimental researches were carried out in dry friction conditions.
