ʻO ka wehewehe ʻana i nā electrodeposits maʻamau - gula

ʻO ka hoʻokomo ʻana i ka uhi gula

1. ʻO ke gula he metala makamae gula i malleable a maʻalahi i ka poli.

2. He paʻa kemika maikaʻi ke gula, ʻaʻole hiki ke hoʻoheheʻe ʻia i nā waikawa maʻamau, hiki ke hoʻoheheʻe ʻia i ka aqua regia

3.Gold coating he ikaika corrosion kū'ē a maikaʻi kū'ē i discoloration

4.He ʻano kala like ʻole ke kala gula, hoʻohana pū ʻia no nā uhi hoʻonaninani pipiʻi

PITCH HEADER WAHINE:2.0MM(.047″) LALANI KAKOLU POLOLEI 180°

5.Gold he haʻahaʻa hoʻopaʻapaʻa pili a me ka conductivity maikaʻi, a hoʻohana pinepine ʻia i nā kūlana hoʻoheheʻe.

6.Gold plating mea oluolu i ka wiliwili a me ka maikai wela kū'ē, kekahi aahu-kū'ē hana, akā, e malama, 'aʻole mānoanoa gula oi maʻalahi i ka wiliwili, ma ke kū'ē, ka mānoanoa o ke gula papa 3-5 ų ° welding hopena. ʻoi aku ka maikaʻi.

7. ʻO ka hoʻohui o ke keleawe i ke gula he mea liʻiliʻi loa ia i ka paʻakikī, akā ʻo ka hoʻohui ʻana o 10% nickel he hopena nui i ka paʻakikī.Ma waho aʻe o kēia, ʻoi aku ka paʻa o ka au-NI alloy.

8. Poor ea tightness o ke gula, lalo gula e loaa diffusion phenomenon.Generally me nickel kumu, waiho e pale gula lalo diffusion

9. He haʻahaʻa hoʻoheheʻe ʻia ke gula a hiki ke hoʻoheheʻe ʻia i loko o ka tin i ka wā nickel welding, ka hopena i ka hoʻokumu ʻia ʻana o nā pūhui AU-SN ​​a me ka hoʻokumu ʻana o ke gula brittleness.

10. Anticorrosive hiki o ke kumu keleawe i hoʻopaʻa 'ia ma nickel ų 50 ° maikaʻi loa, akā, i ka lōʻihi i loko o ka nickel - plating kahi papa o ka kikokikona, corrosion kū'ē hiki i loa poor.The kumu o ka hiki ke okoa ma waena o gula a me Nui loa ka nickel, ka mea i hoʻomaka ai ka hopena corrosion o Galliani.Hōʻike ka hoʻokolohua paʻakai i ka pololei o kēia manaʻo.Ma mua, hiki i ka nickel me ka uhi gula ʻole ke hoʻopau i nā hola he 72, ʻoiai ʻaʻole hiki i ka nickel me ka uhi gula lahilahi ke lōʻihi i 48 mau hola.

ʻO ka hoʻokomo ʻana i ka electroplating tin

1. He keʻokeʻo kālā ke kino.

2.Tin ka corrosion-kū'ē, waihoʻoluʻu-kū'ē, non-meaʻawaʻawa, oluolu e weld a ductile

3.Tin uhi i kiʻekiʻe kemika paʻa

4.Electrical conductivity o ka pani pani mea maikai, oluolu e weld, a pinepine ma kahi o ke kala kala.

5.in ka uhi ʻana i ke ʻano o ka wela tin, akā ʻaʻole me ka bismuth, antimony alloy \

6. ʻO ka uhi ʻana i ka tin ma ka wela kiʻekiʻe, ka pulu, nā kūlana i hoʻopaʻa ʻia e hoʻopuka i nā ʻumi ʻumi.

7. ʻO ka mea hoʻoheheʻe ʻia o ke kinikini-lead alloy he haʻahaʻa ma mua o ke kēpau maʻemaʻe a me ka tin maʻemaʻe, ʻoi aku ka maikaʻi o kona porosity a me ka weldability ma mua o ka metala hoʻokahi, i loko o ka pahu maʻemaʻe e like me ka hoʻohui ʻana o 2-3% alakaʻi, ʻaʻole maʻalahi. e hana i ka ʻumi ʻumi, no laila ʻo ka uhi ʻana i ke alo o ke tin-lead ka mea koʻikoʻi loa i ka uhi ʻana i nā mea uila, hiki ke hoʻololi i ka uhi kālā i loko o kekahi ʻano.

8. Hoʻohana pinepine ʻia no ka hoʻopili ʻana i nā mea a hiki ke hoʻohana ʻia no ka hoʻopili hoʻopili ikaika nui.
