Understanding the interrupted rolling procedure as a post-processing influence on the microstructure and corrosion behavior of the dual-phase composite Mg-8%Li/3%bagasse nanoparticles

The interrupted rolling process was used to decrease the corrosion of Mg-Li8%-3%bagasse composites due to galvanic effect. The stir casting process was used to form a 3% bagasse nanoparticle-reinforced Mg-8% Li composite and then rolled with thickness reductions of 50, 70, and 90%. The generated composite’s corrosion rate drops as the reduction percentage increases, according to research on the rolled composite’s potentiodynamic polarization and electrochemical impedance. Studies on electrochemical impedance show that composites with a 90% thickness reduction have an excellent charge transfer resistance. The appearance of microcracks and pits on the corrosion surface of 0% reduction indicates the occurrence of pitting corrosion. It has been established that interrupted rolling of Mg-8% Li-3% bagasse nanoparticle composites can be used to enhance the corrosion resistance of the composite.
