直流電沉積時,基質金屬的沉積連續進行,粒子在電極表面不間斷嵌入鍍層;單脈沖電沉積由於脈沖間歇的存在使得具有較大體積的粒子會脫附,重新回到溶液中;採用周期換向脈沖時,反向脈沖電流使表面荷正電的較大的粒子更易從電極表面脫附,同時,反向脈沖電流對基質金屬的溶解作用,也會促進粒子的脫附,因此鍍層中復合粒子尺寸最小。隨著鍍層中粒子復合量的增加,三種鍍層的晶粒都明顯細化,說明al _ 2o _ 3的存在阻止了晶粒的長大,提高了電沉積過程中晶核的形成速率。Glyceryl stearate se, dimethicone, stearic acid, batyl alcohol, carbomer, acrylates / c10 - 30 alkyl acrylate crosspolymer, xanthan gum, potassium hydroxide, camellia japonica seed oil, behenyl alcohol, hydrogenated palm oil, morigna pterygosperma seed oil, disodium edta, trifolium pratense ( clover ) flower extract, propylene glycol, phenoxyethanol, theanine, bis - behenyl / isostearyl / phytosteryl / dimer dilinoleyl dimer dilinolate, thermus thermophillus ferment, glycerin, sodium dehydroacetate, potassium sorbate
