除了鍍(du)(du)鉻(ge)液成分影(ying)響(xiang)(xiang)鍍(du)(du)鉻(ge)層的質(zhi)量外，鍍(du)(du)鉻(ge)工(gong)藝參數(shu)的影(ying)響(xiang)(xiang)也是很大的。有(you)時(shi)(shi)因為工(gong)藝參數(shu)不當(dang)而影(ying)響(xiang)(xiang)了鍍(du)(du)層質(zhi)量，有(you)時(shi)(shi)可(ke)以(yi)調(diao)節(jie)電鍍(du)(du)工(gong)藝參數(shu)消除鍍(du)(du)鉻(ge)中的故障。

在鍍鉻溶液(ye)深鍍能力、電(dian)(dian)(dian)(dian)源、陽極等正常的情(qing)況下，可以通(tong)過沖(chong)擊鍍鉻來(lai)避免零件出現的鉻黃現象，沖(chong)擊電(dian)(dian)(dian)(dian)流(liu)(liu)可以是正常電(dian)(dian)(dian)(dian)鍍電(dian)(dian)(dian)(dian)流(liu)(liu)的2倍～4倍，時(shi)間30s～90s，沖(chong)擊電(dian)(dian)(dian)(dian)流(liu)(liu)與沖(chong)擊鍍時(shi)間與零件的外形有關，需要通(tong)過試(shi)驗(yan)來(lai)具體(ti)確定最佳(jia)的沖(chong)擊電(dian)(dian)(dian)(dian)流(liu)(liu)和時(shi)間。

另外對(dui)于(yu)低電(dian)流(liu)密度區(qu)出現(xian)的(de)鉻(ge)黃零件，可(ke)以采(cai)用(yong)輔(fu)助陽(yang)極(ji)或者調整(zheng)電(dian)鍍鉻(ge)工藝(yi)參(can)數的(de)方式來避(bi)免鉻(ge)黃。比如：外形復(fu)雜(za)的(de)鋁合金輪轂，為(wei)了使鋁輪轂的(de)低電(dian)流(liu)區(qu)不(bu)出現(xian)鉻(ge)黃，通常是在電(dian)鍍鎳后采(cai)用(yong)專用(yong)的(de)帶輔(fu)助陽(yang)極(ji)的(de)掛具(ju)進(jin)行電(dian)鍍鉻(ge)。

鍍鉻(ge)鎳底層(ceng)表(biao)面活化不充分(fen)(或(huo)鎳被(bei)鈍(dun)化)使鍍鉻(ge)的深鍍能力變(bian)差(cha)，在低電(dian)流密度(du)區出現鉻(ge)黃(huang)(huang)故(gu)障(zhang)。在生(sheng)產(chan)(chan)中常碰到產(chan)(chan)品退鉻(ge)重(zhong)鍍時(shi)鉻(ge)黃(huang)(huang)現象較(jiao)直接電(dian)鍍.鎳后(hou)鍍鉻(ge)出現的鉻(ge)黃(huang)(huang)現象嚴重(zhong);夏(xia)天(tian)(tian)電(dian)鍍生(sheng)產(chan)(chan)出現的鉻(ge)黃(huang)(huang)故(gu)障(zhang)比冬天(tian)(tian)嚴重(zhong)，其原因(yin)是夏(xia)天(tian)(tian)鍍鎳層(ceng)表(biao)面的鈍(dun)化速度(du)比冬天(tian)(tian)快(kuai)，導致(zhi)出現鉻(ge)黃(huang)(huang)故(gu)障(zhang)。

對這種故障處(chu)理可(ke)以(yi)(yi)采(cai)用電(dian)鍍(du)(du)亮(liang)(liang)鎳(nie)(nie)后(hou)及時(shi)水洗，避免(mian)零(ling)件(jian)與空氣的(de)接觸時(shi)間過長導(dao)致(zhi)鎳(nie)(nie)層表面(mian)(mian)鈍(dun)化(hua)(hua);另外(wai)由于鎳(nie)(nie)鍍(du)(du)層在光亮(liang)(liang)鍍(du)(du)鎳(nie)(nie)溶液(ye)中也很(hen)容易鈍(dun)化(hua)(hua)，所以(yi)(yi)鍍(du)(du)亮(liang)(liang)鎳(nie)(nie)后(hou)也要及時(shi)將零(ling)件(jian)從(cong)亮(liang)(liang)鎳(nie)(nie)液(ye)中取(qu)出，避免(mian)鍍(du)(du)鎳(nie)(nie)零(ling)件(jian)表面(mian)(mian)鈍(dun)化(hua)(hua);鍍(du)(du)鉻(ge)前的(de)活化(hua)(hua)要充分(fen)，可(ke)根據需要增加陰極活化(hua)(hua)或(huo)化(hua)(hua)學活化(hua)(hua)工(gong)序來確保鎳(nie)(nie)鍍(du)(du)層充分(fen)活化(hua)(hua)，具體(ti)可(ke)以(yi)(yi)根據工(gong)廠的(de)具體(ti)情況試(shi)驗確定。

鍍(du)(du)鉻(ge)(ge)電(dian)(dian)流(liu)(liu)密(mi)度(du)參數(shu)不合(he)理也會影響鍍(du)(du)鉻(ge)(ge)的(de)(de)(de)深(shen)鍍(du)(du)能(neng)(neng)力，從理論上講(jiang)，鉻(ge)(ge)的(de)(de)(de)沉積是需要達到一(yi)定(ding)(ding)的(de)(de)(de)電(dian)(dian)流(liu)(liu)密(mi)度(du)，若施加(jia)電(dian)(dian)流(liu)(liu)密(mi)度(du)不合(he)適(shi)，通常(chang)會造成鍍(du)(du)鉻(ge)(ge)故障。另外由(you)于使用了不同鍍(du)(du)鉻(ge)(ge)添加(jia)劑的(de)(de)(de)鍍(du)(du)液其電(dian)(dian)流(liu)(liu)密(mi)度(du)范(fan)圍也是不同的(de)(de)(de)，電(dian)(dian)流(liu)(liu)密(mi)度(du)過低可能(neng)(neng)導致低電(dian)(dian)流(liu)(liu)區零件表(biao)面鍍(du)(du)不上鉻(ge)(ge)，電(dian)(dian)流(liu)(liu)密(mi)度(du)太高可能(neng)(neng)會引起鍍(du)(du)層(ceng)光亮(liang)度(du)下降和燒焦。通常(chang)根據霍(huo)(huo)耳(er)槽試驗(yan)確定(ding)(ding)合(he)理的(de)(de)(de)電(dian)(dian)流(liu)(liu)密(mi)度(du)范(fan)圍，如果(guo)沒(mei)有條件做霍(huo)(huo)耳(er)槽試驗(yan)，則可以直接(jie)在鍍(du)(du)槽中進行電(dian)(dian)流(liu)(liu)密(mi)度(du)的(de)(de)(de)調(diao)整(zheng)來(lai)確定(ding)(ding)合(he)理的(de)(de)(de)鍍(du)(du)鉻(ge)(ge)電(dian)(dian)流(liu)(liu)密(mi)度(du)范(fan)圍。

裝(zhuang)飾(shi)鍍鉻(ge)的深鍍能(neng)力與(yu)鍍液(ye)溫(wen)(wen)度有(you)關，不同(tong)(tong)的鍍鉻(ge)溶液(ye)的溫(wen)(wen)度控制要(yao)求是(shi)不同(tong)(tong)的，具(ju)體的控制范(fan)圍應當根據所采用的鍍鉻(ge)液(ye)以及鍍鉻(ge)產品外形要(yao)求來(lai)確定。鍍鉻(ge)過程中的發熱量大(da)，鍍鉻(ge)液(ye)需(xu)要(yao)同(tong)(tong)時具(ju)備加熱與(yu)冷卻系統(tong)來(lai)控制鍍液(ye)的溫(wen)(wen)度。

鍍鉻掛具需要(yao)考慮零(ling)件(jian)在電(dian)(dian)鍍過(guo)(guo)程中的(de)電(dian)(dian)力線分布(bu)(bu)狀況，盡量使(shi)零(ling)件(jian)各處的(de)電(dian)(dian)力線分布(bu)(bu)均勻，必(bi)要(yao)是要(yao)增加輔助(zhu)陽極或(huo)者輔助(zhu)陰極。要(yao)注(zhu)意鍍鉻過(guo)(guo)程中如何使(shi)低電(dian)(dian)流密(mi)度區與(yu)(yu)陽極相對均勻排布(bu)(bu)，零(ling)件(jian)之(zhi)間不(bu)能互相屏蔽，零(ling)件(jian)的(de)排布(bu)(bu)間距要(yao)合理，這(zhe)些都與(yu)(yu)鍍鉻掛具有(you)關(guan)。

鉻(ge)(ge)是很(hen)易鈍(dun)化(hua)(hua)(hua)的(de)金屬。以常見金屬的(de)鈍(dun)性系(xi)數(shu)為(wei)(wei)(wei)例，Cu、Pb、Sn為(wei)(wei)(wei)0.10，Ni為(wei)(wei)(wei)0.37，Cr為(wei)(wei)(wei)0.74，最高為(wei)(wei)(wei)Ti，達(da)2.44。即鉻(ge)(ge)比鎳易鈍(dun)化(hua)(hua)(hua)得(de)多。鍍鉻(ge)(ge)用(yong)(yong)整(zheng)流(liu)(liu)電(dian)(dian)源必(bi)須是低(di)(di)紋(wen)波(bo)(bo)(bo)的(de)(紋(wen)波(bo)(bo)(bo)系(xi)數(shu)5%以下)，且保持(chi)波(bo)(bo)(bo)形(xing)良好(hao)。因為(wei)(wei)(wei)用(yong)(yong)紋(wen)波(bo)(bo)(bo)系(xi)數(shu)大的(de)直流(liu)(liu)電(dian)(dian)流(liu)(liu)，在(zai)波(bo)(bo)(bo)形(xing)的(de)低(di)(di)谷(gu)處(chu)也可能使鉻(ge)(ge)層(ceng)鈍(dun)化(hua)(hua)(hua)，而在(zai)鈍(dun)化(hua)(hua)(hua)的(de)鉻(ge)(ge)上再鍍鉻(ge)(ge)，必(bi)然灰白，局部鈍(dun)化(hua)(hua)(hua)則起白斑(ban)。鍍鉻(ge)(ge)整(zheng)流(liu)(liu)電(dian)(dian)源可用(yong)(yong)三相(xiang)五柱芯十二相(xiang)整(zheng)流(liu)(liu)帶乎波(bo)(bo)(bo)電(dian)(dian)抗器的(de)低(di)(di)紋(wen)波(bo)(bo)(bo)可控硅整(zheng)流(liu)(liu)器，或者設有足夠容量濾波(bo)(bo)(bo)器的(de)高頻開關電(dian)(dian)源。道理(li)很(hen)簡單，紋(wen)波(bo)(bo)(bo)系(xi)數(shu)小的(de)直流(liu)(liu)電(dian)(dian)是無(wu)法(fa)用(yong)(yong)變(bian)壓(ya)器來變(bian)壓(ya)的(de)。
