style="text-indent:25px">達(dá)克羅涂液種類繁多，但涂液的基本組成可歸納如下:1.金屬物:由鋅、鋁等物質(zhì)組成，主要為超細(xì)鱗片狀鋅、超細(xì)鱗片狀鋁。2.溶劑:為惰性有機(jī)溶劑，如乙二醇等。3.無(wú)機(jī)酸組分:如鉻酸等。4.特殊有機(jī)物:為涂液的增粘分散組份，主要成份為纖維素類白色粉末。達(dá)克羅膜層對(duì)于鋼鐵基體的保護(hù)作用可歸納為以下幾點(diǎn):1.壁壘效應(yīng):由于片狀鋅、鋁層狀重疊，阻礙了水、氧等腐達(dá)克羅產(chǎn)品蝕介質(zhì)到達(dá)基體的進(jìn)程，能起一種隔離的屏蔽作用。2.鈍化作用:在達(dá)克羅的處理過程中，鉻酸與鋅、鋁粉和基體金屬發(fā)生化學(xué)反應(yīng)，生成致密的鈍化膜，這種鈍化膜具有很好的耐腐蝕性能。3.陰極保護(hù)作用:鋅鋁鉻涂層比較主要的保護(hù)作用與鍍鋅層一樣，是對(duì)基體進(jìn)行陰極保護(hù)。</p><p style="text-indent:25px">相對(duì)于部分傳統(tǒng)的電鍍工藝，達(dá)克羅具有更多的優(yōu)勢(shì)。例如使用達(dá)克羅工藝后的產(chǎn)品，防腐蝕性能是傳統(tǒng)鍍鋅的幾十倍，通過鹽霧測(cè)試后發(fā)現(xiàn)，普通達(dá)克羅可以達(dá)到鍍鋅的20倍，而那些長(zhǎng)效達(dá)克羅的測(cè)試時(shí)間會(huì)更長(zhǎng)，在核工業(yè)中的有些部件使用達(dá)克羅工藝，使用壽命能達(dá)到30年。達(dá)克羅不會(huì)像其它電鍍工藝那樣，在受到拉伸和應(yīng)力作用后有裂紋，或者斷裂現(xiàn)象。在高溫環(huán)境下達(dá)克羅有很好的穩(wěn)定性，這比傳統(tǒng)的鍍鋅耐高溫性能要高很多。使用達(dá)克羅工藝后的產(chǎn)品有非常好的抗沖擊性能，所以達(dá)克羅工藝非常適合那些受力部件，這是因?yàn)檫_(dá)克羅滲透性好，能將表面鍍層與產(chǎn)品很好的結(jié)合在一起。達(dá)克羅發(fā)黑是化學(xué)表面處理的一種常用手段，原理是使金屬表面產(chǎn)生一層厚度0.6~0.8微米的氧化膜。</p><div

style="text-indent:25px">達(dá)克羅有良好的滲透性:由于靜電屏蔽效應(yīng)，工件的深孔、狹縫，管件的內(nèi)壁等部位難以電鍍上鋅，因此工件的上述部位無(wú)法采用電鍍的方法進(jìn)行保護(hù)。達(dá)克羅則可以進(jìn)入工件的這些部位形成達(dá)克羅涂層。無(wú)污染和公害:達(dá)克羅在生產(chǎn)加工及工件涂覆的整個(gè)過程中，不會(huì)產(chǎn)生對(duì)環(huán)境有污染的廢水廢氣，不用三廢治理，降低了處理成本。達(dá)克羅的燒結(jié)溫度較高、時(shí)間較長(zhǎng)，能耗大。達(dá)克羅的表面硬度不高、耐磨性不好，而且達(dá)克羅涂層的制品不適合與銅、鎂、鎳和不銹鋼的零部件接觸與連接，因?yàn)樗鼈儠?huì)產(chǎn)生接觸性腐蝕，影響制品表面質(zhì)量及防腐性能。邳州達(dá)克羅表面涂層</p></p><br
