as the shot peening time was prolonged. Once the depth was greater than 0.2 mm, the absolute value of residual compressive stress would gradually increase. This was because shot peening can lead... sufficient time treatment, the surface of the samples was uniform and substantially free of etch pits (Fig. 10(e)). The reason for this was that as the shot peening time was prolonged, the pits were rapidly......

. This liberation of hydrogen during off time in PC electrodeposition method reduces the cracking effect of chromium and produce crack-free coatings [5,7,17]. Therefore, PC electrodeposition technique can lead to less micro-cracking and consequently improving the mechanical properties and corrosion resistance of the Cr-containing coatings [4,5,7,17]. Moreover, the coatings that were prepared at lower......
