不銹鋼化學熱處理發黑法工藝介紹
化(hua)學著(zhu)黑色法又分酸性(xing)(xing)著(zhu)黑色法和(he)堿(jian)性(xing)(xing)著(zhu)黑色法。酸性(xing)(xing)著(zhu)黑色法得到的膜(mo)層色澤均勻(yun),薄而牢固(gu),富有彈(dan)性(xing)(xing),結合力(li)好(hao),但膜(mo)層多(duo)孔,耐磨性(xing)(xing)較(jiao)(jiao)差,要經(jing)過(guo)固(gu)化(hua)處理才能提(ti)高耐磨性(xing)(xing);堿(jian)性(xing)(xing)著(zhu)黑色法著(zhu)色時間(jian)較(jiao)(jiao)長,但黑膜(mo)的耐磨性(xing)(xing)很好(hao),無需固(gu)化(hua)處理。 化(hua)學著(zhu)黑...
