Abstract:
Boron carbide – aluminium (B4C – Al) ceramic – metal composites are promising materials especially in armour applications for body and vehicle protection, where lightness is one of the most important constraints. Boron carbide provides high hardness and elastic modulus to the composite and its low toughness is increased with metal reinforcement via composite production approach. Al is a generally preferred metal with its low density, low melting point and cost effectiveness. Increasing the toughness with minimum loss of hardness and strength is the biggest challenge in such materials. Generally, ceramic – metal composites having high ceramic volume fraction are produced by infiltration of metal reinforcement into the partially sintered or pre – formed ceramic body. In this study, fine and coarse B4C powder compositions were prepared with both non-passivated and passivated powders at 1400 °C for 2 hours. B4C – Al ceramic – metal composites were produced by pressureless melt infiltration into partially Spark Plasma Sintered (SPS’d) B4C bodies. Microstructure and chemical analyses of B4C – Al ceramic – metal composites were correlated with passivation, ceramic and metal content, ceramic particle size and composition of the ceramic content. Results showed that passivation has positive effects on prevention of undesired reaction products.
