Abstract

Fibreboards made of coir fibres were converted to carbon templates by controlled thermal processing which were further infiltrated and reacted with Mo-Si alloy containing 90.4wt% Si, at 1400-1550 degrees C in vacuum. Depending on infiltration temperature the composition of the final composite varied containing mainly SiC, MoSi2, unreacted Si and C. Morphology and the phase distribution of the final Si-Mo-SiC composite determined by scanning electron microscopy and X-ray diffraction technique. Micro-hardness test at different loads was carried out using a Vicker's micro-hardness tester. The sample prepared at 1400 degrees C showed best hardness property.
