        孔蚀 is again metal surface formed small 坑,另一 types type type is comprehensive 腐蚀, ratio 如, iron in gas and water in 时生锈;银暴露 in gas in gloss. also has types 腐蚀叫应 force 腐蚀, is tensile force and ring versus combined material.

         that what is electrical 蚀?常 by made overlook types 腐蚀叫 electrical 蚀, usually by 人们误当 as electrical understanding function. electrical is types different metal in types property electrical understanding liquid in combined generate loss 害. this type of 情况时, reaction in inert property (不太 can resistant this type of 腐蚀)差 metal is cationic 极(positive 极), it 此时腐蚀 speed degree need ratio metal 平时腐蚀 speed degree fast more;而 inert property good metal formed anionic 极(negative 极), it 此时腐蚀 speed degree need ratio metal 平时腐蚀 speed degree slow more.

         mold from electroplating 槽里取出 rear electrical is most Common 腐蚀之一. 例如, will aluminum products 置进一 types electroplating liquid 里. aluminum parts still has small and surface heavy 整处理. aluminum and this types different metal by in 一起. however in aluminum parts 坑凹处 沉淀 镍 need ratio aluminum parts its it 方沉淀 镍 less, therefore 坑凹处就暴露 to 镍,现 in types electrical understanding liquid 就会发生 electrical 蚀.

         how to anti electrical 蚀?首先, need ensure for electrical has understanding. electrical most commonly used methods 叫牺牲 cationic method, its principle is: false positive use solvent liquid electroplating parts aluminum products. false that parts aluminum made parts has defect 话, ratio 如坑,就会 has types can can property: electroplating process in, solvent liquid or water separation will in need made parts defect inner. water separation 子终极 will formed is battery electrical understanding liquid. aluminum inert property ratio 镍材差, therefore in electroplating process in by used for anti and long made parts use lifespan,但实际 in add fast 腐蚀, shrink short made parts lifespan. solution methods is use cationic method.

        严格检查 mold upper small and surface defects, in for its electroplating 处理之 front versus surface treatment; is ensure anti 止腐蚀, need in mold surface upper coating 一层至 less 0.0005in thick 镍层. this most small thick degree 镍层,无论 is for good 无缺 模 parts also is for/regarding can can has or other defect parts is very has necessary.

         electrical is mold and made industry production and development upper 拦路虎. most difficult in large more 数人发现 it 时,模 parts already can 避免, therefore 每 人都 has need 弄清楚 electrical is how 回事, anti 患于未然.
