“…The SEM-EDX element line analysis of composites fabricated with 40 MPa squeeze pressure showed a smooth transition in element concentrations, indicating interdiffusion between carbon fiber (C) and aluminum matrix (Al) across interfaces, as shown in Figure 7. This strong C-Al interdiffusion can be expected to produce strong fiber-matrix interfaces [14,21] and yields properties that are in line with model predictions assuming the ideal case of near-perfect interface bond. [20] As such, squeeze pressures around 40 MPa seem to be optimal, as they allow the needed infiltration and intimate contact between carbon fibers and molten aluminum for improved interface bonding.…”

“…The increased viscosity of the molten aluminum layers primarily due to their oxide envelop also seems to cause the threshold pressure to increase more sharply with the carbon fiber volume fraction as compared with conventional squeeze casting where a similar trend was observed. [13,14] This leads to a limitation of the amount of carbon fiber reinforcement that can be added. Therefore, above a certain reinforcement content, the fabricated laminate composites show poorer mechanical behavior, particularly at higher loads.…”

“…When the carbon fiber volume fraction increased from 2 to 4 vol%, the bend strength dropped by 13.5% and 10% with 0.9 and 4.2 μm thick fiber coatings, respectively. [ 14 ] Moreover, the composites with lower carbon fiber content showed slightly higher Young's moduli.…”

The 2D bend behavior of composites fabricated by the new laminate squeeze casting technique is studied. Particular focus is on effects of the initial alternating solid‐state laminate configuration of aluminum 6061 sheets and carbon fiber fabric. Equibiaxial pin‐on‐ring bend tests are performed. It is shown that hydrostatic pressures around 40 MPa are required, which is at the higher end of the range reported for conventional squeeze casting. This is primarily due to the oxide scale on the aluminum layers that can hinder infiltration and weaken the fiber–matrix interface. However, above the threshold squeeze pressure, flexural modulus, yield strength, and strain hardening modulus continuously increase by up to 11.65%, 90.12%, and 248.28%, respectively. The strong strain hardening behavior suggests initial plastic deformation as pre‐condition for full load transfer to the fibers, indicating that the composites are most efficient when pre‐deformed following casting. Moreover, the ultimate flexural strength improves by up to 322.23% at 3.74 vol% with a maximum value of 1050.95 MPa. The major property improvements are primarily due to the possibility offered by the laminate technique to selectively place the reinforcement at critical sections, in this case, close to the composite surfaces with the highest bend stresses.

“…And metal-coated powders have been successfully prepared on some ceramics powders such as Si 3 N 4 , Al 2 O 3 , Cr 3 C 2 , WC, SiC and so on. [13][14][15][16][17][18] To overcome the wetting problem between the aluminum matrix and the reinforcing agent, Alten et al 19 prepared carbon fibers coated with Ni coating via the electroless technique. With the aim to effectively improve the interface between ZrO 2 toughened Al 2 O 3 (ZTA) particles and metal matrix, nickel was deposited on the surface of ZTA particles by electroless plating method.…”

To solve the poor sinterability and wettability between TiN ceramic and pure metal via using coated composite powders, dense TiN-Ni cermets with uniform microstructure and fine grains were developed at a low sintering temperature of 1300℃ in this work. TiN powders were firstly activated in a strong acid solution, in order to achieve a step-like surface; Ni-coated TiN powders showed an uniform and controllable morphology. Two types of TiN-Ni cermets based on conventional milled powders and Nicoated TiN composite powders were fabricated by spark plasma sintering (SPS), and used for the comparison concerning the sintering behavior, microstructure and related mechanical properties. Results showed that Ni-coated TiN composite powders helped to improve the sinterability between ceramic and metal, which is rather beneficial to obtain dense TiN-Ni cermets with homogeneous microstructure and high mechanical properties. Compared to those of conventional TiN-Ni, the relative density, Rockwell hardness and fracture toughness increased from 84.9% to 96.6%, 80.2 to 84.3, and 10.2 MPa·m 1/2 to 14.7 MPa·m 1/2 , with a rather low sintering temperature of 1300 ℃, respectively.

The effects of reinforcement addition and hot extrusion on the microstructures, micro hardness, friction, and wear behavior of aluminium (Al) hybrid composite were investigated.Al6061 dispersed with electroless nickel-coated Si 3 N 4 (6wt.%) and copper-coated carbon fiber (C f ) (1wt.%) hybrid composites was developed through stir casting followed by hot extrusion. Optical micro structural studies confirmed that the size of reinforcements decreased, and their orientations were in the extrusion direction. The decrease in the grain size (29%) of hybrid composites was larger than that in the grain size of matrix alloys under hot-extruded conditions. The synthesized hot-extruded Al6061 hybrid composite exhibited a lower coefficient of friction (51%) and high wear resistance (39%) compared with the hotextruded Al6061base alloy.
