Corrosion behaviour of sinter forged aluminium composites during hot deformation

A galvanostatic pulse technique was used to determine corrosion behavior of sinter-forged aluminium composites. Specimens were prepared using powder metallurgy (P/M) manufacturing techniques, with two different initial relative density and various carbide reinforcements such as titanium carbide (TiC), molybdenum carbide (Mo2C), iron carbide (Fe3C) and tungsten carbide (WC). The specimens were machined and molded in a thermo-plastic material so that a surface area of 1 cm2 is exposed in a solution of 3.5wt% water solution of NaCl during the corrosion test. The corrosion behavior of the sinter-forged aluminium composites were studied alongside microstructure studies to expose corrosion dynamics and presented in this report
