特殊螺絲公(gong)司如果彈(dan)簧(huang)(huang)(huang)與(yu)(yu)電(dian)(dian)(dian)(dian)(dian)解(jie)質溶液(ye)接(jie)觸(chu)，由(you)于(yu)微(wei)電(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)(de)作用(yong)而產生(sheng)的(de)(de)(de)(de)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)(shi)叫電(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學(xue)(xue)(xue)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)(shi)。彈(dan)簧(huang)(huang)(huang)與(yu)(yu)酸性或(huo)(huo)鹽類溶液(ye)接(jie)觸(chu)，這(zhe)類溶液(ye)都(dou)是電(dian)(dian)(dian)(dian)(dian)解(jie)質，由(you)于(yu)彈(dan)簧(huang)(huang)(huang)表(biao)面的(de)(de)(de)(de)缺陷(xian)或(huo)(huo)雜(za)質等(deng)原因而形成電(dian)(dian)(dian)(dian)(dian)位差不(bu)同的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極以致彈(dan)簧(huang)(huang)(huang)不(bu)斷(duan)受(shou)到電(dian)(dian)(dian)(dian)(dian)解(jie)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)(shi)；又例如彈(dan)簧(huang)(huang)(huang)處在潮濕大氣(qi)(qi)中(zhong)，由(you)于(yu)大氣(qi)(qi)中(zhong)的(de)(de)(de)(de)水蒸氣(qi)(qi)在彈(dan)簧(huang)(huang)(huang)表(biao)面上(shang)(shang)凝成水膜或(huo)(huo)水珠，加上(shang)(shang)大氣(qi)(qi)中(zhong)的(de)(de)(de)(de)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)(shi)性氣(qi)(qi)體（如工(gong)業廢(fei)氣(qi)(qi)中(zhong)的(de)(de)(de)(de)二氧(yang)化(hua)(hua)硫和硫化(hua)(hua)氫或(huo)(huo)海洋大氣(qi)(qi)中(zhong)的(de)(de)(de)(de)鹽霧(wu)等(deng)）溶解(jie)于(yu)水膜或(huo)(huo)水珠中(zhong)形成電(dian)(dian)(dian)(dian)(dian)解(jie)質。再加上(shang)(shang)彈(dan)簧(huang)(huang)(huang)金屬的(de)(de)(de)(de)雜(za)質或(huo)(huo)缺陷(xian)亦可形成電(dian)(dian)(dian)(dian)(dian)位差不(bu)同的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極，彈(dan)簧(huang)(huang)(huang)亦產生(sheng)電(dian)(dian)(dian)(dian)(dian)解(jie)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)(shi)。這(zhe)些都(dou)屬電(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學(xue)(xue)(xue)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)(shi)。 彈(dan)簧(huang)(huang)(huang)受(shou)化(hua)(hua)學(xue)(xue)(xue)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)(shi)是少量(liang)的(de)(de)(de)(de)、緩(huan)慢的(de)(de)(de)(de)，而受(shou)電(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學(xue)(xue)(xue)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)(shi)是主要的(de)(de)(de)(de)、普遍的(de)(de)(de)(de)。但一般來講化(hua)(hua)學(xue)(xue)(xue)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)(shi)與(yu)(yu)電(dian)(dian)(dian)(dian)(dian)化(hua)(hua)學(xue)(xue)(xue)腐(fu)(fu)蝕(shi)(shi)(shi)(shi)(shi)是同時存在的(de)(de)(de)(de)。

特殊螺絲公司(si)的彈(dan)簧在(zai)(zai)制造、存放、使用(yong)(yong)等(deng)過程中(zhong)，經常會遭受周(zhou)圍介質的腐(fu)(fu)(fu)蝕。由(you)于彈(dan)簧在(zai)(zai)工作(zuo)時(shi)是(shi)靠彈(dan)力發揮(hui)作(zuo)用(yong)(yong)，彈(dan)簧被腐(fu)(fu)(fu)蝕后彈(dan)力會發生改變而喪(sang)失功能。所以防(fang)止彈(dan)簧的腐(fu)(fu)(fu)蝕可以保(bao)(bao)證彈(dan)簧的工作(zuo)穩定(ding)，并延長其使用(yong)(yong)壽命。 彈(dan)簧的防(fang)腐(fu)(fu)(fu)方法一(yi)般采用(yong)(yong)保(bao)(bao)護(hu)層，根據(ju)保(bao)(bao)護(hu)層的性(xing)質可分為(wei)：金屬(shu)保(bao)(bao)護(hu)層、化學保(bao)(bao)護(hu)層、非金屬(shu)保(bao)(bao)護(hu)層和暫時(shi)性(xing)保(bao)(bao)護(hu)層等(deng)，在(zai)(zai)此著重介紹前三種方法。不(bu)銹鋼彈(dan)簧和銅線(xian)彈(dan)簧本身就具有一(yi)定(ding)防(fang)腐(fu)(fu)(fu)能力，所以一(yi)般不(bu)進行防(fang)腐(fu)(fu)(fu)處理。
