Processflow:pretreatmentnocyanidealkalicoppernocyanidewhitecoppertinchromeplating Electroplatingadvantages: 1.Highglossofcoatingandhighqualitymetalappearance; 2.ThesubstrateisSUS,Al,Zn,Mgetc;thecostislowforPVD. ElectroplatingDisadvantages: Environmentalprotectionispoor,andenvironmentalpollutionriskisgreater. 二、anodicoxidation Anodizedoxidation:mainlyanodizedoxidationofaluminum,istheuseofelectrochemicalprinciple,togeneratealayerofAl2O(aluminumoxide)filmonthesurfaceofaluminumandaluminumalloy.Thisoxidefilmhasthespecialcharacteristicsofprotective,decorative,insulation,wearresistanceandsoon. characteristic: 1.Enhancethestrength, 2.Realizeanycolorexceptforwhite. 3.RealizenickelsealingholestomeettherequirementsofnickelfreeinEuropeandtheUnitedStatesandothercountries. Technicaldifficultiesandkeypoints: Theyieldlevelofanodizedoxidationisrelatedtothecostofthefinalproduct.Thefocusofimprovingtheoxidationyieldisthesuitableamountofoxidant,thesuitabletemperatureandcurrentdensity,whichrequiresstructuralpartsmanufacturerstoconstantlyexploreandseekbreakthroughsintheproductionprocess. 三、cataphoresis Electrophoresis:usedforstainlesssteel,aluminumalloy,etc.,canmaketheproductpresentavarietyofcolors,andmaintainthemetalluster,whileenhancingthesurfaceperformance,withgoodanti-corrosionperformance. Processflow:pretreatmentelectrophoresisdrying merit: 1.Richincolors; 2.Nometallictexture,andcanmatchsandblasting,polishing,drawing,etc.; 3.Processingintheliquidenvironmentcanrealizethesurfacetreatmentofcomplexstructures; 4.Theprocessismatureandavailableformassproduction. Disadvantages:theabilitytocoverupthedefectsisgeneral,andthedie-castingelectrophoresishashighpretreatmentrequirements 四、Microarcoxidation Microarcoxidation:theprocessofapplyingahighvoltagetotheelectrolytesolution(theweakalkalinesolution)generallytogeneratetheceramicsurfacemasklayer,whichistheresultofthesynergyofphysicaldischargeandelectrochemicaloxidation. Processflow:pretreatmentwithhotwaterwashingandMAOdrying Technicaladvantages: 1.Ceramictexture,darkappearance,nohighlightproducts,delicatefeel,anti-fingerprint; 2.Extensivesubstratematerials:Al,Ti,Zn,Zr,Mg,Nb,anditsalloys; 3.Simplepretreatment,excellentcorrosionresistance,weatherresistance,andgoodheatdissipationperformance. Disadvantages:atpresent,thecolorislimited,onlyblack,grayandothermoremature,brightcolorsaredifficulttoachieveatpresent;thecostismainlyaffectedbyhighpowerconsumption,isoneofthehighestcostinsurfacetreatment. 五、.PVDvacuumplating Physicalgasdeposition(Physicalvapordeposition,PVD):isanindustrialmanufacturingprocess,ismainlyusingphysicalprocessestodepositthinfilmtechnology. processflow: PVDbeforecleaningfurnaceextractiontargetandioncleaningcoatingfinish,coolingaftertreatment(polishing,AFP) technicalfeature: ThePVD(PhysicalVaporDeposition,physicalvapordeposition)canbecoatedonmetalsurfaceswithametalceramicdecorativecoatingwithhighhardplatingandhighwearresistance.
