That micro-grooves have good effect in reducing the friction and wear of contacted friction pair surfaces,enhancing heat transfer and improving lubrication properties. A new method is proposed to fabricate surface textures by using through-mask electrochemical machining with dry-film mask. According to the profiles of micro-grooves,a process of fabricating the micro-grooves and the relevant test system are set up. The experimental results verify that it is feasible to fabricate micro-grooves with good profiles by through-mask electrochemical machining using the dry-film mask.
