NOTE An electrochemical surface trehent of metallic materials is preferable to a mechanic
34、al polish because it produces a smoother surface even if the Ra values are the same. During his type of surface treatment, sharp peak and dey contours will be reduced preferentially because of high current rates at these particular parts.
