BL光亮氰化镀铜工艺 1.适用范围及特点 (1)适用于钢铁、锌合金等基体零件的挂镀和滚镀。 (2)在低氰、中氰和高氰镀铜溶液中,在较宽的温度范围内,阴极静止或移动下,不需要使用换相电源均能得到均匀光亮的镀层。 (3)杂质容忍度高,易于控制。 (4)镀层光亮平滑,结晶细致,孔隙率小。 2.镀液配方和操作条件
3.光亮剂作用和补充 诺切液降低阳极钝化,促进阳极溶解。含量为30~50mL/L。 光亮剂BL一3能使高电流密度区光亮,内含表面活性剂,降低镀层出现针孔的机会。 光亮剂BL-4与BL-3配合使用,能得到由高至低电流密度同样光亮的镀层。 表8-10常规故障及纠正方法
补充方法: ①光亮剂宜少量多次补充,正常生产时每班补充2~3次。 ②诺切液按带出损失补给,BL-3补充量为l00mL/(kA·h),BL-4补充量为300mL/(kA·h)。 ③补充光亮剂后应充分搅拌,使之分散均匀。 4.常规故障及纠正方法(表8-10) 参 考 文 献 1友野理平等著.实用电镀技术全集.赖耿阳译.台北:复汉出版社,l981 2刘烈炜等.材料保护,2004,+7:4 3方景礼.多元络合物电镀.北京:国防工业出版社,1983 4 Henry B(Udylite Co).US2707166.1955 5 John F B(Dayton Bright Copper Co).US2805193,1957 6 John F B(Dayton Bright Copper Co).US2805194,1957 7 Harts-Gerhard C(Udylite Co).U$3267010,1966 8 Hans-Gerhard C(Udylite Co).US3328273,1967 9 Ricgard B(Lee-Ronal,Inc).U$3725220,1973 10 Charles N A(Dayton Bright Copper Co)US3732151 11 0tto K(M&T Chemicals Inc).US4036711,1977 12 Daniel J C(0xy Metal Industries Co).U$4272335,1981 13 Paul A K(Bell Telephone Lab).US4310392 14 Rashkov R.J Applied Electrochemistry,1995,25:608 15 Stoichev D S.Surf Technol,1978,7:427 16 Stoychev D.Bulg Acad Sci,1976,9(4):618 17 Hill M R H.J Eleetroanal Chem,1978,86:179 18 Yokoi M.Denki Kagaku,1983,51:460 19 Stoychev D.Bulg Acad Sci.1973,26:243 20 Stoychev D.J Appl Elactrochem,1996,26;741 21 Pearson T.J Appl Elactrochem,1990,20:196 22 Pearson T.Surf a Coat Technology,1990,42:76 23 Mikulsl is K.Lietuvos TSR Mokslu Akademijos darbai,B Serija,1985,4(149):2755 24 Hill M R H.J Electroanal Chem,1976,68:149 25 Barbieri S C,Mayer L J(OMI International Corp).US 4555315 26 Martin S(Enthone-OMI Inc.)US 5328589 27 Kardos 0,Areilesi D A(M&T Chemicals Inc).US 4009087 28 Dahms W(Schering Aktlengesellschat)US 4181582 29 Mayer L J,Barbieri S C(Hooker Chemical&Plastics Corp.)US 4336114 30 Willis W J(Roheo Inc.)US 4347108 31 Turner D R.J Electrochem Soc,1962,109:798 32 Ke B.J Electrochem Soc,1959,106:382 33 Zukauskaite N.Electrokhimya,1988,24:1567 34 Cotton F A.Advanced Inorganic Chemistry.4"ed.Chichester:Wiley,1980 35 Carlin R L Transition metal chenstry.vol 5.London,New York:Marcel Dekker,1969 36 Shedshadri B S.J Electroanal Chem Interf Elecrochem,1975,61:353 37 Armstrong M J.J Electrochem Soc,1991,1 38:230338 Poling G W.Corr Sci,1970,10:359 39 Zukauskaite N.Sovlet Metallurgy,1989,25:1362 40 Zukauskaite N.Electrokhimya,1988,24:1564 4lHealy J P.J Electroanal Chem,1992,338:167 42 Healy J P.J Electroanal Chem,1992,338:179 43 E ckles,William Edward(R.O.Hull&Company,Inc).US 4038161 44 Abbott C N(Dayton Bright Copper Co).US 3732151 45 Creutz H G(Oxy Metal Industries Corp).US 4110176 46 Watson Angus(M&T Chemicals Inc).US 4376685 47 Miljkovic M.(Pennsylvania Research Corp).US 4786746 48 Van Tilhurg G C.Plating&Surface Finishin9,1984,71(6):78 49 09den C.J Electrochem Soc.,l981,128(3):539 50 Popovich C A.Zaschita Metallov,1985,21(1):140 51刘烈炜等.材料保护,2002,5:22 52许家园等.电镀与精饰,1990,4;31 53 Stoychev D.Trans IMF,1998,76(2):73 54蔡加勒等.高等学校化学学报,l988,1:57 55 Campbell S A.Trans IMF,1997,75(1):10 56 Farndon E E.J Applied Electrochem,1995,25:574 57 Tantavichet N,Pritzker M D.Electrochimic Acta,2005,50:1849 58 Jae Jeong Kim,S00-Kil Kim,Jong-Uk Bae.Thin Solid Films,2002,415:101 59 Jae JeongKim,SotrKilKim,Yong ShikKim.J ElectroanaIChem,2003,542:61 60张瀛洲,周绍民.厦门大学学报自然科学版,l980,2:63 61 Barbieri S C,Mayer L J.(oMI International Corp)US 4555315 62 Sylvin Martin(Enthone-0MIInc)US 5328589 63 0tto KardOS。Donald A Arcilesi(M&T Chemicals Inc)US 4009087 64 Wolfgang Dahms(Schering Aktlengesellschat)US 4181582 65 Linda J Mayer,Stephen C Barbieri(Hooker Chemical&Plastics Corp)US 4336114 66 William J Willis(Rohco Inc)US 4347108 |
