    摘要: 本研究已探討鈉鈣玻璃表面之鍍鋅薄膜及鋅塊在CuSO4/NaCl混合溶液中化成處理之異同。對鋅塊之化成處理而言,化成反應過程如下:首先形成黑色皮膜(Zn、Cu及Cu(OH)2),銅在黑色皮膜與鋅塊之間析出,脫落的黑色皮膜轉變成黃色粉末(Cu2O),黃色粉末轉變成綠色粉末(CuCl2複合物),鋅塊表面覆蓋白色的ZnO。對鍍鋅薄膜而言,首先形成黑色皮膜(Zn、Cu及Cu(OH)2),紅色皮膜(Cu),黃色皮膜(Cu2O)及綠色皮膜(CuCl2)。鍍鋅薄膜在重量百分濃度為0.6%、1.2%及2.3%化成溶液之活化能分別為33.60(J/mol)、28.21(J/ mol)及14.87(J/mol)。
    The conversion coatings of zinc film on the soda-lime silicate surface comparing with bulk zinc in CuSO4/NaCl aqueous solution were investigated. For bulk zinc, first, the black coatings (Zn, Cu and Cu (OH) 2) formed on the surface. Next, copper was precipitated between the black coatings and bulk zinc. Then, part of black coatings fell off and formed the yellow powder (Cu2O). After that, yellow powder turned into green powder (CuCl2 complexes). At last, the surface of bulk zinc was covered by zinc oxide. For zinc film, the change of color was as follows: black coatings (Zn, Cu and Cu (OH) 2), red coatings (Cu), yellow coatings (Cu2O) and green coatings (CuCl2). The activation energy of zinc film for the conversion coatings in 0.6wt%, 1.2wt% and 2.3wt% CuSO4/NaCl aqueous solution are 33.60(J/mol), 28.21(J/mol) and 14.87(J/mol), respectively.
