Nko gukorana no guhinduka kwamateka menshi, iterambere ryihuse murwego rwingufu zisukuye na semiconduction yinganda za diyama, hamwe nubushobozi bwingufu za diyama, hamwe nubushobozi bwo gutunganya ibikoresho byingenzi nibikoresho byo gutunganya ibintu byoroshye. Kugirango ukemure ibyo bibazo, muri rusange inganda zemeza ifu ya diyama ifatanye nibikoresho byicyuma, kugirango utezimbere hejuru, kuzamura kuramba, kugirango utezimbere ubuziranenge bwibikoresho.
Uburyo bwa diyama ya diyama bwo hejuru cyane, harimo no gufata imiti, gushushanya kwa magner, birimo gutoranya neza, ibyiza byo gupfukaho, bikaba byiza gupfukaho, byahindutse inganda ebyiri zisanzwe zikoreshwa.
1. Guhitamo imiti
Diamond ifu ya shimi yimiti ni ugushyira ifu ya diyama yavuwe mubisubizo byo guhuza imiti binyuze mubikorwa byo kugabanya umuti wimiti, gushiraho icyuma cyinshi. Kugeza ubu, icyapa cyakoreshejwe cyane cya diyama ni ickeli ya Nikel arickel-fosifore (ni-p) binary alloy mubisanzwe bita impeta nikel.
01 ibigize imiti ya Nikel
Ibigize igisubizo c'imiti bigira uruhare rukomeye ku iterambere ryoroshye, ituze no guhinga ubwiza bwa shimi. Ubusanzwe ikubiyemo umunyu nyamukuru, kugabanya umukozi, itoroshye, buffer, stilizar, kwihuta, kubaga nibindi bigize. Umubare wa buri gice gikeneye guhindurwa witonze kugirango ugere ku ngaruka nziza zo gutwita.
1, umunyu nyamukuru: mubisanzwe nikel sulfate, Nikel Chloride, Nickel Chloride, Nickel Chloride, Nickel Amino Sulfonic Acide, Nickel Carbonate, nibindi, uruhare rwarwo ni ugutanga isoko ya Nikel.
2. Umukozi wagabanijwe: Ahanini itanga hydrogène ya atomine, igabanya ni2 + mu gisubizo cya ni hanyuma ikayishyiraho hejuru ya diyama, nikintu cyingenzi mubikorwa byo gukwirakwiza. Mu nganda, sodium ya sodium ya sodium hamwe nubushobozi buke bwo kugabanya, igiciro gito kandi ushireho neza gikoreshwa cyane nkumukozi ugabanya. Uburyo bwo kugabanya burashobora kugera ku kwifotora ku bushyuhe buke n'ubushyuhe bwo hejuru.
3, umukozi utoroshye: Igisubizo cyo guhora gishobora kwicisha bugufi, kuzamura imitunganyamiti yo guhora, kunoza umuvuduko wa Nikel, muri rusange aside ya CACCINE, muri CHICT Acide, aside ya CORCOC hamwe nindaya.
4. Ibindi bigize: Ikibaho kirashobora kubuza kubora igisubizo, ariko kubera ko bizagira ingaruka kumiti ya chimique, ikenera gukoresha bisanzwe; Buffer irashobora kubyara h + mugihe cyimiti ya nikel yerekana reaction kugirango ihamye phi ituje; Abarisirwa barashobora kugabanya amayeri.
02 Imiterere ya Chical-Gukora
Gutanga imiti ya sisitemu ya sodium hypophophate isaba ko matrix igomba kugira ibikorwa bimwe na bimwe bya kataleti, kandi ubuso bwa diyama ntabwo ifite ikigo cyibikorwa bya kataletitique, niko bigomba guterwa imbere yibikorwa bya kataletitique, bityo bikaba bigomba kwitegura mbere yifu ya diyama. Uburyo gakondo bwo gutoragura imiti ni ugukuraho amavuta, coarsese, gukangurira no gukora.
. Coarsese irashobora gukora ibyobo bito kandi bikanda hejuru ya diyama, ongera hejuru ya diyama, bidafasha gusa ibyapa ishoro ya diyama, ariko kandi bituma habaho imiti ya elect, ariko igatanga intambwe zo gukura kwizana cyangwa gushinga intambwe ya electroplating.
Mubisanzwe, intambwe yo gukuraho amavuta mubisanzwe ifata igisubizo na alkaline nkuko igisubizo cyo gukuraho amavuta, kandi kumavuta yo gukuraho amavuta, kandi kuri aside ya nitrike hamwe nibindi biti byimiti bikoreshwa nkibisobanuro bya diyama. Mubyongeyeho, aya mahuza yombi agomba gukoreshwa imashini yogusukura ultrasonic, ifasha kunoza imikorere ya diyama yo gukuraho amavuta ya diyama no gukomantaro, bikabike mugihe cyo gukuraho amavuta no kwerekana ingaruka za peteroli no kuganira,
. Gukangurira ni kwamamaza byoroshye kuri okiside iri hejuru yifu ya diyama idafite ubushobozi bwiyorotike. Igikorwa ni ukuzuza impyisi ya acide ya hypophophoshoric na katalytical ions (nkicyuma gikora ibyuma (nkicyuma cya palladium) ku kugabanya ibice bya Nikel, kugirango wihutishe igipimo cyo kubitsa hejuru yifu ya diyama.
Muri rusange, igihe cyo gukangurira no gukoraho ni gito cyane, ibyuma bya diyama palladium ntabwo ari birebire, kandi igihe cyo kuvura kirariroha, kandi igihe cyo kuvura kitoroshye, kandi igihe cya palladium kirariroha, kandi igihe cyiza cyo kuvura no kuvura ni 20 ~ 30min.
. Gakondo yubushyuhe bwa Nikel Nikel, ubushyuhe rusange buzaba muri 80 ~ 85 ℃, byoroshye 85 ℃ Biroroshye Gutanga Igisubizo cyo Gusenya, kandi hejuru ya 85 ℃ Ubushyuhe Ku gaciro ya PH, nkuko PH yongera igipimo cyo kwisiga kizamuka, ariko PH izatera igipimo cya Nikel kibuza igipimo cya sima, bityo bikaba urugero rw'ibipimo by'imiti, bityo bikaba urugero rw'ibipimo by'imiti. icyifuzo cy'iterambere ry'inganda.
Byongeye kandi, igikoma kimwe ntigishobora kugera ku bunini bwiza, kandi hashobora kubaho ibibyimba, pinholes n'izindi ndwara nyinshi zishobora gufatwa kugira ngo ireme ryo gupfumba no kongera ifu ya diyama.
2.
Kubera ko habaho fosiforusi mu gice cyo kuroga nyuma ya diyama ya Nikel, bitera imishinga iboneye y'amashanyarazi yo mu buso bwa Matrix), bityo ibyorezo bidafite aho bikoreshwa mu buryo bw'ibikoresho bya Nikel. Igikorwa cyihariye nugushira ifu ya diyama mubisubizo byigice birimo nikel ions, ibice bya sima kwifuza.
01 Ibigize igisubizo
Kimwe nigisubizo cya chimique, igisubizo cya electraplant gitanga ishyari zikenewe muri gahunda ya electraplating, kandi zigenzura inzira yo kubitsa bya Nikel kugirango ubone icyuma gisabwa. Ibigize ibyayo nyamukuru birimo umunyu nyamukuru, Anode Agent, umukozi wa buffer, inyongeramubindi nibindi.
.
.)
. Umukozi usanzwe ya buffer afite acide ya boric, acide acike, sodium bicarbonate nibindi.
.
02 diyama ya electroplated nikel
1. Pretreatment mbere yo kwiyegurika: Diamond akenshi ntabwo iyobora, kandi igomba gutondeka hamwe nigice cyicyuma mubindi bikorwa byo gupfukirana. Uburyo bwo gukora imiti akenshi bukoreshwa mugukora ikibanza cyicyuma kandi cyijimye, nuko ubwiza bwimiti buzagira ingaruka kumiterere yibanze kurwego runaka. Muri rusange, ibikubiye muri Fosifore mu gihe cyo gupfuka nyuma yo kwipimisha bigize ingaruka zikomeye ku buhanga, kandi hejuru ya fosifore ifite ibibyimba byinshi, ubuso bunini bukabije, ubuso bunini bwa magneti; Igiti cyo hagati cya fosifore gifite imbaraga zo kurwanya ruswa no kwambara; Indwara yo hasi ya fosifore ifite akamaro keza.
Byongeye kandi, ntoya yifu ya porond yifu ya diyama, nini cyane ahantu runaka, iyo byoroshye kureremba, hazashyirwaho imico ya platique, kugirango ikemure imico ya platique, igomba gutanga imico ya platine, igomba kwishyuza ifu ya diyama kugirango iteze imbere ifu yo kunoza induru.
2, ickeli: Kugeza ubu, ifu ya diyama yakunze kwemera uburyo bwo gutoranya, ni ukuvuga igiti cya electraplant cyongeweho igisubizo cya electroplating, binyuze mu guhindura icupa, gutwara ifu ya diyama mu icupa. Mugihe kimwe, electrode nziza ihujwe na Nikel Block, hamwe na electrode mbi ifitanye isano nifu ya viama. Munsi y'ibikorwa by'umurima w'amashanyarazi, nikel ions kubuntu mu gisubizo cyo gukwirakwiza ibyuma nickel hejuru yifu ya viamant. Ariko, ubu buryo bufite ibibazo byo kunonosora bike kandi bidafite ishingiro, bityo uburyo bwa electrode izunguruka bwaje kubaho.
Uburyo bwa electrode ya electrode nukuzenguruka cathode mumasafuriya. Ubu buryo burashobora kongera aho ihurira hagati ya electrode na diyama, ongera imishinga imwe hagati yingingo, kunoza ibintu bidafite ishingiro byo kwinginga, no kunoza imikorere yimikorere ya Diamond.
Incamake ngufi
Nkibikoresho byingenzi byibikoresho bya diyama, uburyo bwo guhindura micropowder ya diyama ninzira yingenzi yo kuzamura imbaraga zo kugenzura matrix no kunoza ubuzima bwa serivisi. Kugirango utezimbere igipimo cyumucanga cyibikoresho bya diyama, igice cya nikel na fosishorus birashobora gufatirwa hejuru ya micropowsder, hanyuma igabyimba igipimo cya posita, no kuzamura imitunganya. Ariko, twakagombye kumenya ko ubuso bwa diyama ubwabwo butagira ikigo gikora catalytique, niko bigomba guterwa imbere mbere yo gukora imiti.
