黄铜化学着色工艺

,(,510640)[]为了在黄铜基材上室温下获得铁锈色棕色枪黑色仿古绿色膜层,研究了黄铜酸性化学着色工艺主要讨论前处理溶液组分pH值和着色时间等因素对着色膜层质量的影响,并提出工艺维护的措施研究结果表明:溶液组分是影响化学着色膜颜色的主要因素,使用时要注意控制其含量;适量的添加剂可以提高色膜质量;总之,只有掌握合理的着色工艺参数,才可以得到满意的着色效果[]黄铜;化学着色;室温;化学镀镀液[]TG177[]A[]1001-3660(2004)05-0055-02ChemicalColoringonBrassXUJin-lai,LUOWei-yin(SouthChinaUniversityofTechnology,Guangzhou510640,China)[Abstract]Inordertoobtainrust,brown,gun-blackandancientgreenfilmsonbrassatroomtemperature,thechemicalcoloringprocessonbrassinacidsolutionwasstudied.Influencesoffactorsforcoloring,pretreatmentprocedure,differentsolutioncomponents,pHdegreeandcoloringtimeandsoononqualityofcoloringfilmonbrasswerediscussed.Furthermore,maintenanceoftheprocesswaspresented.Theresultsshowedthatthesolutioncomponentwastheprimaryfactorthataffectedthequalityofcoloringfilm,whichshouldbecarefullycontrolled.Andthequalityofcoloringfilmcouldbeimprovedbyaddingappropriateadditives.Anyway,forobtaininggoodfilms,parametersforcoloringshouldbeinwellcontrolled.[Keywords]Brass;Chemicalcoloring;Roomtemperature;Electrolessplatingsolution0[]2004-05-15[]110-D85530/0[](1979-),,,(),,,,,,,,,,,,,,,,,1[1]yyyyyyyy()yy()yyy22.1():CuSO450g/LFeCl3FeCl2NH4NO330g/L(J-1)10g/L5~10s40min,,,335Vol.33NO.5200410SURFACETECHNOLOGYOct.200455():Cu(NO3)25g/LSeO23g/L(T-1)10ml/L5~10s30min,,2.2[2]:CuSO410g/LSeO28g/L(T-2)10ml/L20~30s2.3[3]():CuSO420g/LSeO28g/L(T-3)10ml/L2~3min,([4]):CuSO420g/LCaCl25g/LNiCl24g/LNH4NO320g/L10~20s,3,,,,,3.1,;,,3.2,,,,;,;,;,,,,,,,,;,3.3(J-1),,,;(T-1);(T-2)(T-3)3.4,,,,,,3.5pHpH,,pH,;pH,,pH2.0~3.03.6,,,,,;,;,,,4,;,;;pH,,,[][1].[J].,2001,30(2)B31~32[2]...[J].,1995,7(2)B37~45[3].[M].:,2000.165[4].[J].,2002,23(4)B176~17756
