Melt Infiltration Casting

This study aims to investigate the effect of volume fraction of commercially pure titanium (CP-Ti) on microstructural, mechanical, and tribological features of A356 aluminum matrix composites. Vacuum-assisted melt infiltration casting was performed to produce composites with 50%, 65%, 75%, and 80% CP-Ti contents. CP-Ti sawdusts were assembled under mechanical pressure in order to attain porous one-piece CP-Ti preforms which were infiltrated by A356 melt at 730 °C under 10−5 Pa vacuum atmosphere. TiAl3 layer was formed at the interface between A356 and CP-Ti phases. Owing to increased diffusion time through decreased diffusion path length, both thickness and hardness of TiAl3 phase were increased with increasing CP-Ti ratio, whereas the best wear resistance was obtained at 65% CP-Ti ratio. The main reason for decrease in wear resistance of 75% and 80% CP-Ti reinforced composites was fragmentation of TiAl3 layer during wear process due to its excessively increased brittleness. Strongly bonded TiAl3 phase at the interface provided better wear resistance, while weakly bonded ones caused to multiply wear rate.

Alumina/glass composites were successfully fabricated by melt-infiltration of glass into porous alumina pellets. Alumina powder was first pressed uniaxially at 100MPa to form disc-shaped pellets, then, heated up to 1200°C for 2 h to form porous pellets with moderate strength for subsequent infiltration. A mixture of calcium aluminosilicate and magnesium borosilicate glass powders were melt-infiltrated into porous alumina at 1200°C ~1250°C by capillary pressure to form composites. The infiltration depths varied with the square root of infiltration time. And the activation energy of the infiltration process was estimated to be 621 KJ/mole. After complete infiltration, the composite had bulk density approaching 3.3 g/cm3 (~ 96% of theoretical density) and open porosity reaching zero, with slight expansion of 0.5% in diameter. Its flexural strength was 150MPa and its Vickers microhardness was about 1000 Kg/mm2.

In this research work the mechanical and erosion wear behavior of E-Glass fiber reinforced epoxy based hybrid composites were determined. Fillers like coal fly ash (CFA), Coal powder (CP) and mixture of coal fly ash and coal powder (CFA-CP) at different weight proportions of 0wt%, 5wt% and 10wt% were mixed with Epoxy Resin and composites were fabricated by manual hand lay-up technique with 50wt% of Glass Fiber as reinforcement and the prepared composites were cut in to specimens as per ASTM standards for mechanical characterizations like tensile, flexural, ILSS, Impact and Hardness properties and erosion wear behavior. Experimental analysis shows that the tensile strength of unfilled Epoxy-Glass composites is maximum (252.189MPa) where as for 10wt% coal fly ash filled epoxy-glass composites tensile modulus is maximum (7.823 GPA). The flexural strength and ILSS are 750.54 MPa and 25.188 MPa respectively for 10 wt% CP filled hybrid composites. The impact strength and hardness are 2100 J/m and 62Hv for 10wt% CFA-CP filled epoxy composites. Coming to erosion wear behavior of composites filled with CFA-CP have exhibited maximum erosion wear resistance when compared with CFA filled epoxy composites. It is observed that with the increase in weight percentages of the filler material. The mechanical properties and erosion wear resistance of the composites were enhanced. Hence, for structural applications filler materials mixed Glass- Epoxy hybrid composites can be used in place of plain glass fiber reinforced epoxy composites due to the enhanced properties of composites.
