鈦(tai)是一種(zhong)易(yi)鈍(dun)化(hua)金(jin)屬(shu)，在(zai)大氣、多數的酸(suan)(suan)性(xing)(xing)水溶液（含氟的酸(suan)(suan)例外(wai)）中(zhong)，鈦(tai)的表(biao)面(mian)極(ji)(ji)(ji)易(yi)生成(cheng)導電(dian)(dian)(dian)(dian)不(bu)良(liang)(liang)的氧化(hua)膜，增加了鈦(tai)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)表(biao)面(mian)的接(jie)觸電(dian)(dian)(dian)(dian)阻，接(jie)觸電(dian)(dian)(dian)(dian)阻的存在(zai)不(bu)僅額外(wai)增加了能(neng)耗、降低陽極(ji)(ji)(ji)使用壽命(ming)，也改變了電(dian)(dian)(dian)(dian)解槽(cao)槽(cao)壓(ya)的可控性(xing)(xing)，也改變了電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)反應(ying)的種(zhong)類(lei)。因此，在(zai)鈦(tai)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)產品的生產過程中(zhong)，均需要在(zai)鈦(tai)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)鍍覆一層(ceng)導電(dian)(dian)(dian)(dian)性(xing)(xing)能(neng)良(liang)(liang)好、不(bu)易(yi)鈍(dun)化(hua)的金(jin)屬(shu)表(biao)面(mian)層(ceng)形成(cheng)了各(ge)類(lei)不(bu)溶性(xing)(xing)鈦(tai)電(dian)(dian)(dian)(dian)極(ji)(ji)(ji)。

       鈦陽極制備工藝：鈦基體加工定型（鈦材加工成型鈦基體）→鈦基體的表面處理（為了增加基體的有效面積，增強涂層與鈦基體的結合力，通常用10%～15%堿或衣粉煮沸去油，然后用10%～15%的草酸煮沸刻蝕）→涂敷與燒制（根據不同用途要求，將Ru，Ir，Sn，Ti，Pd，Ta，Co，Ni等的鹵化物按不同比例配成醇的溶液→涂敷→烘干→氧化燒制，并反復多次制成所需的鈦陽極）→質量檢驗→出廠。
