耐腐(fu)蝕(shi)性：
鈦在(zai)較多(duo)(duo)的(de)(de)介質(zhi)(zhi)中(zhong)(zhong)(zhong)(zhong)有(you)很強(qiang)(qiang)的(de)(de)耐(nai)(nai)蝕(shi)性(xing)，尤其是在(zai)中(zhong)(zhong)(zhong)(zhong)性(xing)及(ji)氧(yang)(yang)化(hua)性(xing)介質(zhi)(zhi)中(zhong)(zhong)(zhong)(zhong)的(de)(de)耐(nai)(nai)蝕(shi)性(xing)很強(qiang)(qiang)，也可用于某(mou)些(xie)稀還原(yuan)性(xing)酸中(zhong)(zhong)(zhong)(zhong)，如常溫(wen)直到沸點的(de)(de)各種濃度的(de)(de)硝酸中(zhong)(zhong)(zhong)(zhong)。對大多(duo)(duo)數堿溶(rong)(rong)液(ye)(ye)具良(liang)好耐(nai)(nai)蝕(shi)性(xing)，如室(shi)溫(wen)的(de)(de)氫氧(yang)(yang)化(hua)鋇、氫氧(yang)(yang)化(hua)鈣、氫氧(yang)(yang)化(hua)鎂飽和溶(rong)(rong)液(ye)(ye)，但不可用于沸騰的(de)(de)氫氧(yang)(yang)化(hua)鈉溶(rong)(rong)液(ye)(ye)。鈦在(zai)海水(shui)中(zhong)(zhong)(zhong)(zhong)完全不被腐蝕(shi)，大多(duo)(duo)數有(you)機酸中(zhong)(zhong)(zhong)(zhong)也很耐(nai)(nai)蝕(shi)（除甲酸、草酸）。 在(zai)濕氯氣及(ji)亞氯酸鹽(yan)、次氯酸鹽(yan)等氯化(hua)物溶(rong)(rong)液(ye)(ye)中(zhong)(zhong)(zhong)(zhong)具有(you)優異的(de)(de)耐(nai)(nai)蝕(shi)性(xing)。在(zai)氯化(hua)鈉溶(rong)(rong)液(ye)(ye)中(zhong)(zhong)(zhong)(zhong)的(de)(de)耐(nai)(nai)蝕(shi)性(xing)隨(sui)溶(rong)(rong)液(ye)(ye)pH值的(de)(de)升高(gao)而提高(gao)。
應用(yong)領域：航空宇航、化工(gong)裝備等。
