2) surface after polishing is by after adopting the cleaning-drying such as acetone, dehydrated alcohol, it is placed in heater, at being heated to 200-1000 DEG C with the heating rate of 1-20 DEG C/min, heat treatment 0.1-24 hour, then natural cooling, generates metal oxide layer at rough surface by heat treatment；
3) will enter in silane or siloxanes or silicon fluoride or fluoroolefins or mercaptan or polyolefin or fatty acid or oil or the mixture pure material of wax or above-mentioned substance or its ethanol or methanol or propanol or ethylene glycol solution through polishing and heat treated immersion metal, low whipping speed soaks 5 seconds-24 hours under being 0-2000 rev/min, natural cooling after solidifying 5 seconds-24 hours under-200 ° of C of room temperature；Or the mixture pure material of silane or siloxanes or silicon fluoride or fluoroolefins or mercaptan or polyolefin or fatty acid or oil or wax or above-mentioned substance heat volatilization under temperature 30-300 ° of C, by through polishing and heat treated metal is placed in above the above-mentioned substance of volatilization natural cooling after 5 seconds-24 hours；By said method, namely obtain the metal with super hydrophobic surface。
The present invention has a major advantage in that:
1. this method is compared to common method for preparing super-hydrophobic surface etch, and used chemical reagent is mainly a small amount of low-surface-energy modifying agent, and process is substantially pollution-free, and environment friendly is high, safe operation process。
2. this method is simple, only need to polish and heat treatment just can realize micron and the nanostructured on surface, not need expensive equipment, and preparation flow is simple, it is easy to accomplish industrialization large-scale production。
3. this method can at conventional engineering metal such as ferrum, copper, aluminum, titanium, nickel and on alloy scale prepare super hydrophobic surface, with low cost, have a extensive future。
