Interaction of boron suboxide with compacted graphite cast iron

The chemical interaction of boron suboxide (B6O) with compacted graphite cast iron (CGI) was investigated using static interaction diffusion couples between B6O and CGI at 700°C, 900°C and 1100°C for 1h. This interaction offers the possibility to evaluate the potential of B6O as a cutting tool. The...

Summary:The chemical interaction of boron suboxide (B6O) with compacted graphite cast iron (CGI) was investigated using static interaction diffusion couples between B6O and CGI at 700°C, 900°C and 1100°C for 1h. This interaction offers the possibility to evaluate the potential of B6O as a cutting tool. The microstructures and phase compositions of the interaction zones were investigated. At 700°C and 900°C the chemical interaction was minimal. However, at 1100°C, Fe2B and SiO2 were formed at the interface. Hence, machining at 1100°C is likely to result in chemical wear.
