宏觀上均勻的腐蝕破壞叫均勻腐蝕。接觸腐蝕兩種電位不同的金屬或合金互相接觸,并浸于電解質(zhì)溶解質(zhì)溶液中,它們之間就有電流通過,電位正的金屬腐蝕速度降低,電位負(fù)的金屬腐蝕速度增加。選擇性腐蝕合金中某一元素由于腐蝕,優(yōu)先進(jìn)入介質(zhì)的現(xiàn)象稱為選擇性腐蝕?？孜g集中在金屬表面?zhèn)€別小點上深度較大的腐蝕稱為孔蝕,或稱小孔腐蝕、點蝕。縫隙腐蝕在金屬表面的縫隙和被覆蓋的部位會產(chǎn)生劇烈的縫隙腐蝕。沖刷腐蝕沖刷腐蝕是由于介質(zhì)和金屬表面之間的相對運動而使腐蝕過程加速的一種腐蝕。晶間腐蝕晶間腐蝕是優(yōu)先腐蝕金屬或合金的晶界和晶界附近區(qū)域,而晶粒本身腐蝕比較小的一種腐蝕。應(yīng)力腐蝕破裂()和腐蝕疲勞是在一定的金屬一介質(zhì)體系內(nèi),由于腐蝕和拉應(yīng)力的共同作用造成的材料斷裂。氫破壞金屬在電解質(zhì)溶液中,由于腐蝕、酸洗、陰極保護(hù)或電鍍,可以產(chǎn)生因滲氫而引起的破壞。3·冷卻介質(zhì)對金屬腐蝕的影響工業(yè)上使用**多的冷卻介質(zhì)是各種天然水。影響金屬腐蝕的因素很多,主要的幾個因素及其對幾種常用金屬的影響:溶解氧水中的溶解氧是參加陰極過程的氧化劑,因此它一般促進(jìn)腐蝕。當(dāng)水中氧的濃度不均勻時,將形成氧的濃差電池,造成局部腐蝕。板式換熱器應(yīng)用場景有哪些？湖南防腐蝕換熱器的用途和特點</p><p
