1、摘要超雙疏具有自清潔、防腐、減阻等性能，在工農(nóng)業(yè)領(lǐng)域得到廣泛應(yīng)用。本文采用復(fù)合加工手段制備超雙疏鋁合金表面，并對其超雙疏機(jī)理進(jìn)行分析，研究結(jié)論如下:1、采用高速電火花線切割在鋁合金表面制備出超疏水表面，并對加工參數(shù)進(jìn)行了試驗優(yōu)化，研究了各因素對接觸角的影響規(guī)律；經(jīng)化學(xué)刻蝕和修飾后，實現(xiàn)了超雙疏鋁合金表面的制備，優(yōu)化了化學(xué)刻蝕試劑的濃度和刻蝕時間。2、采用激光刻蝕在鋁合金表面構(gòu)建微米級方柱結(jié)構(gòu)，并對加工參數(shù)進(jìn)行了試驗優(yōu)化，研究了各因素對接觸角的影響規(guī)律；經(jīng)電火花和化學(xué)修飾后，實現(xiàn)了超雙疏鋁合金表面的制備。3、由于超雙疏鋁合金表面獨特
