Effect of machining configuration on the corrosion of mild steel

The effect of machining parameters (rake angle and turning speed) at fixed feed rate and depth of cut on corrosion behavior of mild steel is addressed in the present study along with analysis of tribological properties of the machined samples. Immersion and salt-fog exposure tests in 3.5% NaCl are carried out to understand the corrosion behavior of the machined samples. Detailed microstructural characterization of the machined samples (optical metallography and scanning electron microscopy) and their rust constituents as determined by Fourier transform infrared spectroscopy is used to establish microstructure-properties correlation.
