濟南生產熱噴涂用生產熱噴涂增(zeng)強涂(tu)(tu)(tu)(tu)層(ceng)與(yu)工(gong)(gong)(gong)件(jian)結合強度(du)熱噴(pen)(pen)(pen)涂(tu)(tu)(tu)(tu)工(gong)(gong)(gong)藝是噴(pen)(pen)(pen)涂(tu)(tu)(tu)(tu)手法當(dang)中的(de)(de)一種(zhong)，金屬(shu)噴(pen)(pen)(pen)涂(tu)(tu)(tu)(tu)采用這種(zhong)手法能夠根據(ju)受(shou)熱情況的(de)(de)不同得到相應可以呈現(xian)出來的(de)(de)效果。熱噴(pen)(pen)(pen)涂(tu)(tu)(tu)(tu)加工(gong)(gong)(gong)是將熔(rong)融狀態的(de)(de)噴(pen)(pen)(pen)涂(tu)(tu)(tu)(tu)材料(liao)，通(tong)過高(gao)速氣流使(shi)其霧化(hua)噴(pen)(pen)(pen)射在零(ling)件(jian)表面(mian)上，形成噴(pen)(pen)(pen)涂(tu)(tu)(tu)(tu)層(ceng)的(de)(de)一種(zhong)金屬(shu)表面(mian)加工(gong)(gong)(gong)方(fang)法。我們把特殊的(de)(de)工(gong)(gong)(gong)作表面(mian)叫 “涂(tu)(tu)(tu)(tu)層(ceng)”，把制造(zao)涂(tu)(tu)(tu)(tu)層(ceng)的(de)(de)工(gong)(gong)(gong)作方(fang)法叫“熱噴(pen)(pen)(pen)涂(tu)(tu)(tu)(tu)”，它是采用各(ge)種(zhong)熱源進行噴(pen)(pen)(pen)涂(tu)(tu)(tu)(tu)和(he)噴(pen)(pen)(pen)焊的(de)(de)總稱。熱噴(pen)(pen)(pen)涂(tu)(tu)(tu)(tu)加工(gong)(gong)(gong)的(de)(de)涂(tu)(tu)(tu)(tu)層(ceng)有兩(liang)種(zhong)，分(fen)別為噴(pen)(pen)(pen)涂(tu)(tu)(tu)(tu)層(ceng)和(he)噴(pen)(pen)(pen)熔(rong)層(ceng)。那(nei)么，這兩(liang)種(zhong)熱噴(pen)(pen)(pen)涂(tu)(tu)(tu)(tu)技術之間有什么區別呢? 1、工(gong)(gong)(gong)件(jian)受(shou)熱情況的(de)(de)不同

的(de)(de)(de)防(fang)腐涂(tu)料(liao)(liao)(liao)-這種涂(tu)料(liao)(liao)(liao)的(de)(de)(de)選擇(ze)是復(fu)雜的(de)(de)(de)，因(yin)為零(ling)(ling)件(jian)在使用中，環境(jing)溫度和(he)各(ge)種介質對涂(tu)層材(cai)料(liao)(liao)(liao)有一些(xie)要(yao)求(qiu)。通常采用鈷基合(he)金、鎳基合(he)金和(he)氧化(hua)物陶瓷作為涂(tu)層材(cai)料(liao)(liao)(liao)，通過提高涂(tu)層的(de)(de)(de)致密性來防(fang)止(zhi)腐蝕(shi)介質的(de)(de)(de)滲透(tou)。合(he)理選擇(ze)涂(tu)層材(cai)料(liao)(liao)(liao)和(he)零(ling)(ling)件(jian)基體的(de)(de)(de)氧化(hua)/還(huan)原電(dian)位(wei)，防(fang)止(zhi)電(dian)化(hua)學腐蝕(shi)，涂(tu)覆密封劑以抑(yi)制(zhi)腐蝕(shi)。4.導(dao)電(dian)或(huo)(huo)(huo)絕緣涂(tu)料(liao)(liao)(liao)-這些(xie)涂(tu)料(liao)(liao)(liao)分(fen)為以下幾類：(1)導(dao)電(dian)涂(tu)層-典(dian)型的(de)(de)(de)涂(tu)層是銅涂(tu)層。(2)絕緣涂(tu)料(liao)(liao)(liao)-典(dian)型的(de)(de)(de)涂(tu)層是氧化(hua)鋁涂(tu)層。(3)屏蔽涂(tu)層-典(dian)型的(de)(de)(de)電(dian)磁干擾(EMI)或(huo)(huo)(huo)高頻干擾(RFI)涂(tu)層是銅涂(tu)層。5.回收涂(tu)料(liao)(liao)(liao)-這些(xie)涂(tu)層主要(yao)用于修復(fu)磨損或(huo)(huo)(huo)加工太(tai)差(cha)的(de)(de)(de)零(ling)(ling)件(jian)。涂(tu)料(liao)(liao)(liao)材(cai)料(liao)(liao)(liao)的(de)(de)(de)選擇(ze)主要(yao)取決于零(ling)(ling)件(jian)的(de)(de)(de)使用要(yao)求(qiu)。

一(yi)(yi)方(fang)面，經過(guo)(guo)封(feng)閉處(chu)理的(de)(de)涂(tu)(tu)層(ceng)可以起(qi)到物理覆蓋作用(yong)。將鋼(gang)鐵(tie)與水和空氣等腐蝕(shi)介質隔離(li)開來，從而(er)起(qi)到防護(hu)(hu)作用(yong)；另(ling)一(yi)(yi)方(fang)面，當涂(tu)(tu)層(ceng)有(you)孔隙、裂紋或損(sun)壞(huai)時，由于鋅(xin)和鋁(lv)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)化(hua)學性能(neng)比(bi)較(jiao)活潑，電(dian)(dian)(dian)(dian)(dian)(dian)極(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)位比(bi)鋼(gang)低(di)，構(gou)成(cheng)腐蝕(shi)電(dian)(dian)(dian)(dian)(dian)(dian)池時，鋅(xin)或鋁(lv)是負(fu)極(ji)(ji)(ji)，鐵(tie)是正極(ji)(ji)(ji)，鋅(xin)、鋁(lv)失(shi)去電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)，變成(cheng)離(li)子(zi)(zi)進(jin)(jin)入(ru)電(dian)(dian)(dian)(dian)(dian)(dian)解質溶液(ye)中(zhong)而(er)被腐蝕(shi)，其自由電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)流向鋼(gang)鐵(tie)，使鋼(gang)鐵(tie)極(ji)(ji)(ji)化(hua)而(er)受到保(bao)護(hu)(hu)。鋁(lv)是一(yi)(yi)種活性很強的(de)(de)金屬，很容易與氧(yang)結合，生成(cheng)一(yi)(yi)層(ceng)致密、堅硬(ying)的(de)(de)氧(yang)化(hua)保(bao)護(hu)(hu)層(ceng)，有(you)效的(de)(de)防止鋁(lv)涂(tu)(tu)層(ceng)進(jin)(jin)一(yi)(yi)步氧(yang)化(hua)。而(er)且噴涂(tu)(tu)過(guo)(guo)程中(zhong)，鋁(lv)變成(cheng)負(fu)電(dian)(dian)(dian)(dian)(dian)(dian)性更強的(de)(de)活化(hua)狀態(tai)，能(neng)更好的(de)(de)對(dui)鋼(gang)鐵(tie)基體(ti)起(qi)陰極(ji)(ji)(ji)保(bao)護(hu)(hu)作用(yong)。噴涂(tu)(tu)后采用(yong)低(di)粘度(du)涂(tu)(tu)料，對(dui)涂(tu)(tu)層(ceng)進(jin)(jin)行封(feng)孔處(chu)理并加一(yi)(yi)、二(er)道面漆，成(cheng)為以金屬為基礎的(de)(de)復合涂(tu)(tu)層(ceng)，將進(jin)(jin)一(yi)(yi)步顯著(zhu)提高涂(tu)(tu)層(ceng)防蝕(shi)能(neng)力，延長保(bao)護(hu)(hu)周期。由于超音速電(dian)(dian)(dian)(dian)(dian)(dian)弧噴涂(tu)(tu)（熱(re)噴涂(tu)(tu)）時鋅(xin)或鋁(lv)呈熔(rong)融液(ye)噴射到經過(guo)(guo)粗化(hua)處(chu)理的(de)(de)鋼(gang)鐵(tie)表(biao)面上(shang)，熔(rong)融有(you)較(jiao)大的(de)(de)熱(re)能(neng)，獲得比(bi)有(you)機涂(tu)(tu)層(ceng)進(jin)(jin)一(yi)(yi)步氧(yang)化(hua)。而(er)且噴涂(tu)(tu)過(guo)(guo)程中(zhong)，鋁(lv)變成(cheng)負(fu)電(dian)(dian)(dian)(dian)(dian)(dian)性更強的(de)(de)活化(hua)狀態(tai)，能(neng)更好地對(dui)鋼(gang)鐵(tie)基體(ti)起(qi)陰極(ji)(ji)(ji)保(bao)護(hu)(hu)作用(yong)。

技(ji)術(shu)優點(dian)(dian)優勢(shi)1.設備簡單(dan)，可就地施(shi)工(gong)(gong)。2.工(gong)(gong)藝靈(ling)活，操(cao)作(zuo)程(cheng)序少(shao)，可快速修(xiu)復(fu)(fu)，縮(suo)短加工(gong)(gong)時間。3.適應(ying)性強，一(yi)般不受工(gong)(gong)件大小(xiao)和位置的(de)(de)限(xian)制。4.可操(cao)作(zuo)涂(tu)(tu)層(ceng)厚度(du)。5.除噴(pen)焊(han)外，基體加熱(re)溫(wen)度(du)低，工(gong)(gong)件變(bian)(bian)形小(xiao)，金相(xiang)組織和功(gong)(gong)能變(bian)(bian)化小(xiao)。6.可根據(ju)各(ge)(ge)(ge)種(zhong)(zhong)固體材(cai)料(liao)的(de)(de)外觀制備各(ge)(ge)(ge)種(zhong)(zhong)防(fang)護(hu)涂(tu)(tu)層(ceng)和功(gong)(gong)能涂(tu)(tu)層(ceng)，適用于各(ge)(ge)(ge)種(zhong)(zhong)基體材(cai)料(liao)。特(te)點(dian)(dian)從熱(re)噴(pen)涂(tu)(tu)技(ji)術(shu)的(de)(de)原理和過程(cheng)分(fen)析，熱(re)噴(pen)涂(tu)(tu)技(ji)術(shu)具有(you)以下特(te)點(dian)(dian)。由于熱(re)源的(de)(de)溫(wen)度(du)范(fan)圍(wei)很(hen)廣，可噴(pen)涂(tu)(tu)的(de)(de)涂(tu)(tu)層(ceng)數據(ju)幾乎包含(han)了所有(you)的(de)(de)固體工(gong)(gong)程(cheng)數據(ju)，如(ru)金屬、合金、陶(tao)瓷(ci)、金屬陶(tao)瓷(ci)、塑料(liao)以及(ji)由它們組成(cheng)的(de)(de)復(fu)(fu)合材(cai)料(liao)。因此，可以賦予基體各(ge)(ge)(ge)種(zhong)(zhong)功(gong)(gong)能(如(ru)耐磨，耐蝕，耐高溫(wen)，抗(kang)氧化，絕(jue)緣，隔熱(re)，生物相(xiang)容(rong)，紅外吸收等)。

特征(1)噴涂(tu)材料須(xu)是導電的。(2)電弧溫度(du)低(di)于等離子體，但高(gao)于氧乙(yi)炔火焰(yan)，霧化絲的壓縮空氣(qi)壓力較高(gao)，噴涂(tu)層(ceng)更致密。(3)同(tong)時送兩根線，噴涂(tu)效率高(gao)。使用適用于噴施大(da)型軸、輥及大(da)型結構件的長期防(fang)護(hu)。
