Sekoahelo sa 1149 sa Nikele e Khanyang ea Barrel
tlhaloso ea lihlahisoa
▪ Ts'ebetso ena e bonts'a matla a ikhethang a ho lahlela, e netefatsang ho beoa ho ts'oanang esita le li-geometri tse rarahaneng le likoti tse tebileng. Botsitso ba bate bo bolokoa ka nako e telele, ka ho bola ho fokolang ha li-additives tsa tlhaho, tse tlatsetsang boleng bo tsitsitseng ba ho phuthela. Sebopeho sa electrolyte se kenyelletsa li-brighteners tse khethehileng le li-agent tse leka-lekaneng tse ntlafatsang matla a ho lahlela a manyane, e leng se fellang ka qetello e boreleli le e bonahatsang ea bokaholimo.
▪ Ts'ebetso ena e tsamaellana le litlhophiso tsa rack le li-barrel plating, e fana ka ho tenyetseha ha ho sebetsana le boholo le bophahamo ba mesebetsi e fapaneng. Bate e sebetsa ka katleho ka har'a mocheso o pharaletseng, hangata pakeng tsa 45°C le 65°C, e ka fetoloang ho latela litlhoko tse itseng tsa ts'ebeliso. Boemo ba pH bo laoloa ka hloko ka har'a moeli o moqotetsane, hangata pakeng tsa 3.8 le 4.5, ho ntlafatsa sekhahla sa ho beoa le thepa ea ho koahela.
▪ Bongata ba li-ion tsa nickel ka har'a tharollo ea plating bo bolokoa ka har'a 70 ho isa ho 90 g/L, ha li-ion tsa chloride li bolokoa pakeng tsa 10 ho isa ho 20 g/L ho netefatsa hore anode e senyeha hantle le hore e tsamaisa motlakase. Tšebeliso ea li-anode tsa nickel tse hloekileng haholo, tse kopantsoeng le mekotla ea anode, e fokotsa ho kenngoa ha litšila le lintho tse nyenyane ka bateng.
▪ Ts'ebetso ena e kenyelletsa litsamaiso tse tsoetseng pele tsa ho sefa, hangata li sebelisa li-cartridge tsa sefe tsa micron tse 5 ho isa ho tse 10, ho tlosa lintho tse tiileng tse emisitsoeng le ho boloka ho hlaka ha bate. Teko e tloaelehileng ea sele ea Hull e etsoa ho lekola ts'ebetso ea bate le ho lokisa mahloriso a tlatsetso ha ho hlokahala. Ho tsitsa ha lera la nickel le kentsoeng hangata ho feta 8%, joalo ka ha ho lekantsoe ke teko ea spiral contractometer, ho netefatsa ts'ebetso e ntle haholo ts'ebetsong ea ho theha kamora ho plating.
▪ Bothata ba seaparo bo ka lokisoa pakeng tsa 250 ho isa ho 450 HV ka ho fetola diparamente tsa bate le dikarolelano tsa tlatsetso, e leng se etsang hore e lokele ditshebediso tse fapaneng tsa indasteri. Tshebetso ena e bontsha dibopeho tse ntle tsa ho kgomarela, ka diteko tsa matla a ho hlohlora tse fetang 8 N/mm² ka mehla. Khanyetso ya ho kgohlopa ha depositi ya nickel, jwalo ka ha e hlahlobilwe ke teko ya ho fafatsa ka letswai, hangata e feta dihora tse 96 ho kgohlopa e tshweu le dihora tse 200 ho kgohlopa e kgubedu ha e kwalwa hantle.
▪ Matla a ikhethang a ho lahlela macro a bate, hangata a fetang 80% joalo ka ha a lekantsoe ke sele ea Haring-Blum, a netefatsa kabo e ts'oanang ea botenya ba ho roala. Ts'ebetso ena e sebetsa haholo bakeng sa likarolo tse phahameng tsa karolelano ea aspect, ka phapang ea botenya hangata e ka tlase ho 15% ho pholletsa le mosebetsi. Khatello e tlase ea ka hare ea depositi, hangata e ka tlase ho 10 MPa joalo ka ha e lekantsoe ke spiral contractometer, e fokotsa kotsi ea ho petsoha kapa ho arohana.
▪ Ts'ebetso ena e kenyelletsa litsamaiso tsa ho beha leihlo ka nako ea sebele bakeng sa liparamente tsa bohlokoa tse kang mocheso, pH, le mahloriso a tšepe, ho netefatsa boleng bo tsitsitseng ba ho betla. Tšebeliso ea li-additives tse tsoetseng pele tsa tlhaho tse nang le thepa e itlhophisang e tlatsetsa bophelong bo bolelele ba ho hlapa, hangata li feta 12 MTO (liphetoho tsa tšepe) ntle le ho senyeha ho hoholo boleng ba ho betla. Ts'ebetso ena e etselitsoe ho fihlela maemo a thata a indasteri, ho kenyeletsoa le litlhaloso tsa ASTM B689 le ISO 1456 bakeng sa liphahlo tsa nickel tse nang le electrodeposition.
