Copper busbars muaj cov khoom siv hluav taws xob zoo heev hauv kev faib hluav taws xob thiab hluav taws xob sib txuas hluav taws xob (kev coj ua tau ncav cuag ntau dua 98% IACS) thiab yog cov khoom siv zoo tshaj plaws rau kev nqa cov dej loj. Txawm li cas los xij, liab qab tooj liab busbars ntsib peb qhov teeb meem engineering hauv qhov chaw siv tiag tiag. Ua ntej, tooj liab yog yooj yim oxidized nyob rau hauv atmospheric ib puag ncig. Nyob rau hauv ib txwm kub thiab av noo tej yam kev mob, cuprous oxide (Cu₂O) thiab tooj liab oxide (CuO) yuav raug tsim rau ntawm tooj liab. Ob lub oxides no muaj cov hluav taws xob tsis zoo, thiab lawv qhov kev tiv thaiv yog ntau qhov kev txiav txim siab ntau dua li ntawm cov hlau tooj liab. Raws li lub sijhawm ua haujlwm dhau los, cov oxide txheej maj mam thickens, ua rau kev sib cuag ntawm lub busbar overlap nto mus txuas ntxiv, ua rau hauv zos overheating. Nyob rau hauv cov xwm txheej hnyav, nws yuav ua rau qhov chaw sib txuas raug hluav taws xob lossis hluav taws xob hluav taws xob. Qhov thib ob, lub hardness ntawm tooj liab yog tsawg (lub annealed hardness ntawm ntshiab tooj liab yog hais txog 40-60 HV). Thaum bolted kev sib txuas tau ua, qhov chaw sib cuag yog qhov yooj yim rau nkag los yog indentation deformation nyob rau hauv siab. Qhov kev deformation no yuav txo qhov kev ua tau zoo ntawm qhov chaw sib cuag thiab ua rau qhov kev sib cuag tsis zoo ntxiv. Tshwj xeeb tshaj yog nyob rau hauv lub voj voog siab tam sim no, cov thermal expansion thiab contraction cuam tshuam yuav ua kom cov txheej txheem degradation. Thib peb, nyob rau hauv qee qhov chaw tshwj xeeb (xws li cov tshuaj tsuag ntsev ntawm ntug dej hiav txwv, thaj chaw muaj kuab paug, muaj peev xwm electrolyte to hauv lub roj teeb), tooj liab kuj yuav raug corroded los ntawm chloride ions los yog sulfides, ua patina los yog tooj liab sulfide corrosion khoom.

 

Nickel plating yog kev paub daws teeb meem engineering los daws cov teeb meem saum toj no. Nickel plating forms a dense physical barrier on the copper surface - nickel itself has a high standard electrode potential and has a strong tendency to passivate in the atmospheric environment. Ib qho nyias nyias (li 1-2nm) thiab ntom nickel oxide passivation zaj duab xis yuav sai sai rau saum npoo. Cov zaj duab xis passivation no tuaj yeem raug crushed nyob rau hauv kev sib cuag siab los tsim hlau conduction thiab yuav tsis txuas ntxiv thicken lub sij hawm xws li tooj liab oxide zaj duab xis. Raws li qhov tshwm sim, Nickel-Plated Copper Flat Bus Bar tuav ruaj khov tsis muaj kev tiv thaiv nyob rau lub sijhawm ua haujlwm ntev. Nyob rau tib lub sijhawm, lub hardness ntawm npib tsib xee txheej (150-300 HV) yog siab dua li ntawm tooj liab matrix. Qhov saum npoo ntawm txheej yog tsis yooj yim rau indentation deformation thaum bolt txuas. Txawm tias nyob rau hauv ntau yam disassembly thiab sib dhos los yog kev co, lub siab tis ntawm qhov chaw sib cuag tuaj yeem nyob ruaj khov. Tsis tas li ntawd, npib tsib xee plating muaj kev ua siab ntev rau cov tshuaj chloride ions, sulfides thiab tsis muaj zog acid ib puag ncig, ua cov nickel-plated tooj liab busbars muaj kev nyab xeeb siv nyob rau hauv corrosive ib puag ncig xws li ships, offshore platforms, lub zog cia roj teeb packs thiab industrial electroplating rhiav. Nyob rau hauv cov ntsiab lus, npib tsib xee plating yog ib qho zoo tshaj plaws engineering kev coj ua los txhim kho oxidation tsis kam, tiv tauj stability thiab ib puag ncig adaptability ntawm busbars yam tsis muaj kev txi cov khoom ntawm tooj liab.
