Intangiriro yo gushiraho zahabu

1. Zahabu nicyuma cyizahabu cyiza kandi cyoroshye kandi cyoroshye.

2. Zahabu ifite imiti ihamye, idashobora gushonga muri acide zisanzwe, zishonga gusa muri aqua regia

3.Ipfundikizo ya zahabu ifite imbaraga zo kurwanya ruswa kandi irwanya amabara

4.Isahani ya zahabu ifite amabara atandukanye, ikoreshwa kandi muburyo buhebuje bwo gushushanya

UMUYOBOZI W'UMUGORE: 2.0MM (.047 ″) URUGENDO RUGENDE RUGENDE 180 °

5.Inzahabu ifite imbaraga nke zo guhangana no gutwara neza, kandi ikoreshwa kenshi mugushushanya ibintu.

6.Isahure ya zahabu iroroshye gusudira kandi ifite ubushyuhe bwiza bwo kurwanya ubushyuhe, imikorere imwe n'imwe irwanya kwambara, ariko witondere, ntabwo zahabu yijimye byoroshye gusudira, kurundi ruhande, ubunini bwurwego rwa zahabu 3-5 ų ° gusudira ni byiza.

7.Kwongera umuringa muri zahabu ntabwo bigira ingaruka nke mubukomere, ariko kongeramo nikel 10% bigira ingaruka zikomeye kubukomere.Uretse ibyo, au-NI alloy ifite ituze ryinshi.

8.Umwuka muke wa zahabu, zahabu yo hepfo izaba ifite diffusion phenomenon. Muri rusange hamwe na nikel base, va kugirango wirinde gukwirakwiza zahabu hasi.

9. Zahabu ifite aho ishonga kandi irashobora gushonga byoroshye mumabati mugihe cyo gusudira nikel, bigatuma habaho ibice bya AU-SN ​​no gushiraho ubwiza bwa zahabu.

10 nikel nini cyane, itera kwihuta kwangirika kwa Galliani.Ikigeragezo cyo gutera umunyu cyerekana ko iki gitekerezo ari cyo.Ubusanzwe, nikel idafite isahani ya zahabu yoroheje ishobora kumara amasaha 72, mugihe nikel ifite isahani yoroheje idashobora kumara amasaha 48.

Intangiriro ya tin electroplating

1.Tin ifite isura ya silver-yera.

2.Tin irwanya ruswa, irwanya ibara, idafite uburozi, byoroshye gusudira no guhindagurika

3.Gutwikiriye amabati bifite imiti ihamye

4.Ibikoresho by'amashanyarazi bifata amabati nibyiza, byoroshye gusudira, kandi akenshi mumwanya wamabati

5.mu gutwikira bifite phenomenon ya tin fever, ariko ntabwo hamwe na bismuth, antimony alloy \

6.Gutwikira amabati hejuru yubushyuhe bwinshi, butose, ibintu bifunze bizatanga amabati.

7.Ikintu cyo gushonga cya tin-gurşine ya ali iri munsi yicyuma cyiza na tini isukuye, ububobere bwacyo hamwe no gusudira biruta icyuma kimwe, mumabati yera mugihe cyose hiyongereyeho 2-3%, ntabwo byoroshye kubyara tin whisker, bityo tin-lead alloy coating nicyo kintu cyingenzi gishobora kugurishwa mubice bya elegitoroniki, birashobora gusimbuza ifeza ya feza murwego runaka.

8.Bikunze gukoreshwa mubikoresho byo gusudira kandi birashobora no gukoreshwa muburyo bwiza bwo guhuza imbaraga.
