“…This study clearly shows the excellent wear properties of the MoAlB. Recently, Gupta et al showed that the addition of MAX phase (Ti 3 SiC 2 ) particulates enhanced the mechanical and tribological performance of base metals and polymers.…”

In this paper, we report the synthesis and characterization of polylactic acid (PLA)‐MAX (Ti3SiC2, Ti3AlC2, and Cr2AlC) and PLA‐MoAlB composites by fused deposition modeling (FDM). Detailed scanning electron microscopy (SEM) studies showed that the particulate phases are uniformly dispersed in the PLA matrix of 3D‐printed samples. Differential scanning calorimetry (DSC) results showed that the addition of MAX phases promoted crystallization of PLA matrix as compared to MoAlB particulates. The mechanical testing results showed that the PLA matrix is sensitive to the addition of MAX or MoAlB phases, for example, PLA‐5 wt% Ti3SiC2, PLA‐5 wt% Ti3AlC2, and PLA‐5 wt% Cr2AlC had a UTS of ~39 MPa, ~30.5 MPa, and ~38.7 MPa as compared to ~41.5 MPa in pure PLA. Comparatively, PLA‐5 wt% MoAlB had a UTS of ~23.2 MPa which shows that predominantly amorphous PLA‐MoAlB composites have lower strength. The tribological behavior improved after the addition of 1 wt% additives, for example, in PLA‐Cr2AlC, the friction coefficient decreased by 76% to ~0.26 from ~0.34 in pure PLA, and the WR marginally decreased in PLA‐1 wt% Cr2AlC to ~2.2 × 10−5 mm3/Nm as compared to 7.7 × 10−5 mm3/Nm in PLA. SEM investigations of the tribosurfaces showed the tribology is governed by the formation of tribofilms. The wettability study showed that all the 3D‐printed samples are hydrophilic in nature.

“…Second, the presence of microporous defects at the interfaces of the composites generated stress concentration points. [ 37 ] Once the volume fraction of SSW increased, stress concentration points within the unit volume of the composite increased as well, leading to localized stress concentration. Additionally, with increasing temperature, thermal softening occurred, further reducing the shear performance of the composites.…”

High‐performance lightweight composites are developed by integrating metal rubber (MR) into a zinc alloy (ZA8) matrix via squeeze casting. MR, comprising 304 stainless steel wires with diameters of 0.15 mm, forms three‐dimensional network skeletons with volume fractions of 8.8 vol.% (S1), 11.1 vol.% (S2), and 13.4 vol.% (S3), respectively. The preparation parameters of the composites are optimized, and their micro‐hardness is investigated. Special attention is paid to the ultimate compression and shear performance at 25 °C, 150 °C, and 250 °C. The microstructure and failure analysis are performed via SEM. The results reveal a 48.0% increase in micro‐hardness at composite interfaces relative to ZA8. At 25 °C, S2 possesses an ultimate compressive strength (UCS) of 401.4 MPa, which is 33.7% higher than that of ZA8. At 150 °C and 250 °C, S3 exhibits UCS values of 180.3 MPa and 74.3 MPa, exceeding those of ZA8 by 61.7% and 110.5%, respectively. Meanwhile, the ultimate shear strength of composites slightly drops below that of the matrix: the corresponding value of S1 specimen (158.4 MPa) at 250°C is 11.5% below that of ZA8. Therefore, compression and shear failure mechanisms of MR/ZA8 composites are quite intricate, involving SSW separation, necking, and ZA8 fractures.This article is protected by copyright.

“…In earlier studies, we have observed similar behavior where the addition of stiffer Ti 3 SiC 2 particulates makes the densification of these composites difficult. 25,26 Comparatively, the hardness of PEEK sample was $141 MPa, it increased to $169 MPa in PEEK-5%312Si, thereafter, it decreased gradually to $152 MPa and $123 MPa in PEEK-80%312Si and PEEK-70%312Si, respectively (Figure 2(a)). The increase in porosity of the composites as the concentration of Ti 3 SiC 2 is responsible for the lower hardness of the composites at higher concentration of Ti 3 SiC 2 particulates in the PEEK matrix.…”

In this article, the authors report the synthesis and tribological behavior of Ti3SiC2–PEEK composites during dry sliding. These composites were designed by adding 5 vol.% (PEEK–5%312Si), 10 vol.% (PEEK–10%312Si), 20 vol.% (PEEK–20%312Si), and 30 vol.% Ti3SiC2 (PEEK–30%312Si) particulates in the PEEK matrix. Tab-on-disc method was used to study the tribological behavior of these samples during self-mating. As the Ti3SiC2 content in PEEK was increased from 0 to 30 vol.%, the µmean decreased from ∼0.19 to ∼0.14 in PEEK–10%312Si, thereafter, it increased to ∼0.21 in PEEK–20%312Si and PEEK–30%312Si, respectively. The addition of Ti3SiC2 particulates had a huge on impact on the wear resistance, e.g. PEEK–5%312Si was 27 times more wear resistant than the PEEK. It is hypothesized that the presence of Ti3SiC2 particulates lubricated the tribocontact areas and assisted in the formation of Type IIIa lubricious tribofilms.
