Ihe mkpuchi 3.Gold nwere nguzogide corrosion siri ike na ezigbo nguzogide ngbanwe

4.Ntinye ọla edo nwere agba dị iche iche, A na-ejikwa ihe mkpuchi ịchọ mma dị oke ọnụ

NKWUKWU NSỌ NKE NWANYI:2.0MM(.047″) ahịrị atọ nke ọma 180°

5.Gold nwere obere nguzogide kọntaktị na ezigbo conductivity, a na-ejikarị ya eme ihe na ọnọdụ kọntaktị na-amị amị.

6.Gold plating dị mfe ịgbado ọkụ na nwere ezi okpomọkụ na-eguzogide, ụfọdụ wear-eguzogide arụmọrụ, ma na-elekọta, ọ bụghị oké gold ọzọ mfe ịgbado ọkụ, na Kama nke ahụ, ọkpụrụkpụ nke gold oyi akwa 3-5 ų ° ịgbado ọkụ mmetụta. kacha mma.

7.Mgbakwunye ọla kọpa na ọla edo nwere obere mmetụta na ike siri ike, ma mgbakwunye 10% nickel nwere mmetụta dị ukwuu na ike.E wezụga nke ahụ, au-NI alloy nwere nkwụsi ike dị elu.

8.Ogbenye ikuku tightness nke gold, ala gold ga-diffusion phenomenon.Generally na nickel isi, hapụ iji gbochie gold ala diffusion

9.Gold nwere ebe mgbaze dị ala ma dị mfe soluble na tin n'oge ịgbado ọkụ nickel, na-eme ka e guzobe ogige AU-SN ​​na nhazi nke brittleness gold.

10. Anticorrosive ike nke mbụ ọla kọpa alloy plating na nickel ų 50 Celsius dị ezigbo mma, ma dị ka ogologo oge na nickel – plating a oyi akwa nke a ederede, corrosion eguzogide ikike bụ nnọọ poor.The mere bụ na nwere ike dị iche n'etiti gold na nickel buru ibu, nke na-ebute mmeghachi omume corrosion nke Galliani.Nnwale ịgba nnu na-egosi na echiche a ziri ezi.Na mbụ, nickel na-enweghị plasta ọla edo dị gịrịgịrị nwere ike ịdịru awa 72, ebe nickel nwere obere ọla edo enweghị ike ịdịru awa 48.

Okwu mmalite nke tin electroplating

1.Tin nwere ọdịdị ọlaọcha-ọcha.

2.Tin bụ corrosion-eguzogide, agba na-eguzogide ọgwụ, na-adịghị egbu egbu, mfe weld na ductile

3.Tin mkpuchi nwere elu chemical kwụsie ike

4.Electrical conductivity nke tin mkpuchi dị mma, dị mfe weld, na mgbe na ebe ọlaọcha tin.

5.in mkpuchi nwere ihe ngosi nke tin fever, ma ọ bụghị na bismuth, antimony alloy\

6.Tin mkpuchi na elu okpomọkụ, mmiri mmiri, akara ọnọdụ ga-emepụta tin whiskers.

7.The agbaze ebe tin-lead alloy bụ ala karịa dị ọcha ndu na dị ọcha tin, ya porosity na weldability dị mma karịa otu metal, na dị ọcha tin dị ka mgbakwunye na nke 2-3% ndu, ọ dịghị mfe. mepụta tin whisker, ya mere mkpuchi mkpuchi tin-lead alloy bụ ihe mkpuchi kachasị mkpa na-emezigharị na ngwa elektrọn, nwere ike dochie mkpuchi ọlaọcha n'ime oke.

8.Ọ na-ejikarị maka ịgbado ọkụ ihe na nwekwara ike-eji maka ibu nti ike kọntaktị mkpuchi.
