“…Indeed, compared to the monolithic materials, wear resistance can generally be enhanced by introducing a secondary phase(s) into the matrix material [1][2][3][4][5][6]. In this fashion, the wear properties can be varied substantially through changes in the microstructure, in terms of the morphology, volume fraction and mechanical properties of the reinforcing phase, and the nature of the interface between the matrix and reinforcement.…”

SUMMARY:A simple physically-based model for the abrasive wear of composite materials is presented based on the mechanics and mechanisms associated with sliding wear in soft (ductile) matrix composites containing hard (brittle) reinforcement particles. The model is based on the assumption that any portion of the reinforcement that is removed as wear debris cannot contribute to the wear resistance of the matrix material. The size of this non-contributing portion of the reinforcement is estimated by modeling the three primary wear mechanisms, specifically plowing, interfacial cracking and particle removal. Critical variables describing the role of the reinforcement, such as its relative size and the nature of the matrix/reinforcement interface, are characterized by a single contribution coefficient, C. Predictions are compared with the results of experimental two-body (pin-on drum) abrasive wear tests performed on a model aluminum particulate-reinforced epoxy matrix composite material.

“…The hardness of the MMCs increases with the volume fraction of particulates in the alloy matrix. The higher hardness of the composites can be attributed to the fact that B 4 C particles act as obstacles to the motion of dislocation [21][22][23][24][25]. As shown, hardness increases with the amount of present B 4 C particles.…”

In the present study, attempts were made to coat the B4C powders with TiB2 via a sol-gel process, and then squeeze cast A356 matrix composites reinforced with coated B4C particles were fabricated. X-ray diffraction studies also confirmed the existence of boron carbide and some other reaction products such as TiB2, AlB2 and Al3BC in composite samples. It was observed that the amount of porosity increased with increasing the volume fraction of composites. Tensile behavior and hardness of unreinforced alloy and composites were evaluated. It was noted that the elastic constant, strain-hardening and UTS of the metal matrix composites (MMCs) were higher than those of the un-reinforced Al alloy and increased with increasing of coated B4C content. The strengthening of particulate reinforced metal-matrix composites is associated with a high dislocation density in the matrix due to the difference in coefficient of thermal expansion between the reinforcement and the matrix.

“…These techniques include stir casting [13][14][15], liquid metal infiltration [16], Squeeze casting [17] and spray co-deposition [18]. Stir casting route is generally practiced commercially [19][20][21]. Its advantage lies in its simplicity, flexibility and applicability to large quantity of production.…”

In this investigation, an attempt has been made to develop Al6061-Frit particulate metal matrix composites through stir casting technique using metal molds and to study the corrosion behaviour. Pre heated frit particles were added to matrix as reinforcement. Al6061 containing 2 wt% to 8 wt% in steps of 2 wt% of frit particulate composites were prepared. Corrosion tests were conducted by using Potentiostat model SEP238C where 3.5% NaCl solution was used as corrodent. The corrosion rate of metal matrix composites was lower than that of matrix material Al6061 under the corrosive atmosphere for both un-heat treated and heat treated conditions.
