“…Therefore, it is critical to have better understanding of erosion wear phenomenon of polymer composite materials. Over the past decade, the researchers utilized different conventional metal [ 1 ] and ceramic materials as reinforcements for development of high wear resistant composite materials. Though conventional materials have established their competence in sustaining wear some of the drawbacks like high self‐weight, cost and non‐renewable made researchers to choose polymer composites which have high specific and strength inherent lubricant properties.…”

Porous carbon materials have versatile physical and chemical characteristics; however, these materials are not be fully exploited as reinforcements in polymer composites. The present investigation focuses on extraction of hierarchical porous carbon and its utilization in polymer composite in order to enhance the erosion wear resistance and hardness of polymer composite. The current research work also demonstrates the wear behavior of the hierarchical porous carbon epoxy composite when exposed to different environmental conditions. The attributes of hierarchical carbon have verified through different characterization techniques, further porous carbon with optimum properties has been included as reinforcement in different ratios viz. 1, 2 and 3 wt. % to make the epoxy composites. The composites were studied for their hardness, moisture absorption and erosion wear behavior at variable impingement angles (30°, 45°, 60°, and 90°) and impingement velocities (101, 119, and 148 m/s). Moisture uptake results suggests that the increase in filler percentage increased the moisture absorption, and the highest moisture absorption was reported in composite immersed in saline water environment. It was observed that addition of activated carbon particles has enhanced hardness and wear resistance of the composite. Composite with 2 wt.% particulate reinforcement was found to be the optimum percentage of reinforcement which was subjected to 82.4% less material loss that is, erosion rate at 45° impact angle compared to neat polymer. From the erosion wear results it was further noticed that moisture absorption has deteriorated the erosion wear resistance of composites resulting in high material loss.

“…30 Mechanical and erosive behavior of stepped polymeric functionally graded materials reinforced with aluminum was studied and it was found that by varying the filler content, gradation is achieved along the sample's thickness direction. 31 Comparing the sliding wear behavior of 10 wt% SiC particle-reinforced aluminum matrix composite (AMC) with that of cenosphere-filled aluminum syntactic foam (ASF), the research has been done. It was discovered that, in both dry and lubricated settings, ASF exhibits lower coefficients of friction, wear rates, and temperature increases than AMC.…”

This study aims to investigate the factors that affect the abrasion of cenosphere‐reinforced syntactic foams and assess their three‐body wear behavior using Taguchi's design of experiments (L16 Orthogonal array). Cenospheres were dispersed into an epoxy matrix to create syntactic foam samples. The findings show that the syntactic foams' rate of wear was influenced by the cenosphere concentration. Reduced wear rate was obtained with a greater cenosphere concentration. Duration and applied force both had an impact on how quickly the syntactic foams wore out. This research can help in the creation of wear‐resistant composite materials for a variety of applications by illuminating the variables influencing the abrasion of cenosphere‐reinforced syntactic foams. The findings demonstrate that sp. rate of wear is minimum (0.124 × 10−8 m3/Nm) at the factor combination of 60% loading of filler, 40 N of applied load and duration of 15 min which can be indicated as A4B4C2. This is 10.56 times better than the combination A1B4C4 which exhibits an sp. wear rate of 1.31 × 10−8 m3/Nm. These lightweight syntactic foams have the potential to be used as tribo‐materials in friction applications, such as composite brake pads.

“…These materials can be fabricated using powder metallurgy (PM), additive manufacturing, vapor deposition, centrifugal casting, and so on. 5,6 Among the processes, PM is widely used to develop metal–metal FGMs owing to its fabrication ease and ability to produce complex geometries. PM includes mixing of metal powders and compression in a mold followed by sintering and cooling in a furnace.…”

A five-layered aluminum–copper metal functionally graded material was developed through powder metallurgy process. The sample comprises different weight percentages of copper and aluminum that vary from 0 wt% to 100 wt % along the thickness direction. Erosion wear was performed on air jet erosion testing apparatus at a constant impact angle of 90o and impact velocity of 151 m/s. It was observed that erosion wear decreases when there is an increase in copper content. Layer 1 comprising 100 wt% of copper has shown 76.92% lower wear compared to layer 5 (100 wt% of aluminum). Besides, erosion resistance was enhanced at graded layers due to the formation of Al2Cu phase during sintering. Abrasive wear of metal functionally graded material was evaluated on the pin-on-disc test apparatus. Experiments were conducted at different loading conditions on various abrasive surfaces (P120, P800, and P2000). Irrespective of abrasive surface, the specific wear rate of aluminum–copper metal functionally graded material sample increased with an increase in load from 5N to 15N. At 5N, abrasive wear of metal functionally graded material on P2000 grit surface was 87.7% and 27.19% lower compared to P120 and P800, respectively. Eroded and worn-out surfaces were examined microscopically to understand the wear mechanisms and are discussed in detail.
