I loko o ka ʻoihana electroplating, ua huki ka pulse power electroplating i ka manaʻo ma muli o kāna hana uhi kiʻekiʻe. Ke hoʻohālikelike ʻia me ka electroplating DC kuʻuna, hiki iā ia ke loaʻa nā uhi me nā kristal ʻoi aku ka maikaʻi, ʻoi aku ka like, a me ke kiʻekiʻe o ka maʻemaʻe. ʻOiaʻiʻo, ʻaʻole kūpono ka pulse electroplating no nā kūlana āpau, loaʻa iā ia kāna ʻano hana ponoʻī.
No laila, he aha nā noi nui o ka pulse electroplating? Hoʻomaka kēia me kāna mau pono koʻikoʻi.
1. ʻOi aku ka maikaʻi o ka crystallization o ka uhi ʻana
I ka wā o ke alakaʻi ʻana o ka pulse, hiki i ke au kiʻekiʻe ke piʻi i nā manawa he nui a ʻoi aku paha ma mua o ʻumi manawa o ke au DC. ʻOi aku ka nui o ke au i kahi overpotential kiʻekiʻe, e hoʻonui nui ana i ka helu o nā ʻātoma i hoʻopili ʻia ma ka ʻili cathode. ʻOi aku ka wikiwiki o ka nucleation rate ma mua o ka ulu ʻana o ka kristal, e hopena ana i kahi uhi crystallized maikaʻi. Loaʻa i kēia ʻano uhi ka density kiʻekiʻe, ka paʻakikī kiʻekiʻe, ka liʻiliʻi o nā pores, a ʻoi aku ka maikaʻi o ke kūpaʻa ʻana i ka corrosion, ke kūpaʻa ʻana i ka ʻaʻahu, ka welding, ka conductivity, a me nā waiwai ʻē aʻe. No laila, hoʻohana nui ʻia ka pulse electroplating i nā kahua electroplating hana e pono ai ka hana kiʻekiʻe.
2. ʻOi aku ka maikaʻi o ka hoʻopuehu ʻana
Loaʻa i ka electroplating pulse ka hiki ke hoʻopuehu maikaʻi, he mea nui ia no kekahi electroplating hoʻonaninani. No ka laʻana, i ka wā e uhi ai ke gula a i ʻole ke kālā i nā ʻāpana hana nui, hiki i ka electroplating pulse ke hoʻolilo i ke kala i ʻoi aku ka like a me ke kūlana paʻa. I kēia manawa, ma muli o ka hoʻohui ʻana o kahi ʻano kaohi waho, ua emi ka hilinaʻi ʻana o ka maikaʻi o ka uhi ʻana i ka hopena ʻauʻau, a ua maʻalahi ka kaohi hana. No laila, i kekahi mau electroplating hoʻonaninani koi nui, loaʻa mau ka waiwai o ka electroplating pulse. ʻOiaʻiʻo, no ka electroplating hoʻonaninani pale maʻamau, e like me nā paikikala, nā mea paʻa, a pēlā aku, ʻaʻole pono e hoʻohana.
3. ʻOi aku ka maʻemaʻe o ka uhi ʻana
I ka wā o ka pulse off, hana ʻia kekahi mau kaʻina hana desorption maikaʻi ma ka ʻili cathode, e like me ke kinoea hydrogen i hoʻopili ʻia a i ʻole nā mea haumia e hoʻokaʻawale ana a hoʻi i ka hopena, a laila e hōʻemi ana i ka hydrogen embrittlement a hoʻomaikaʻi i ka maʻemaʻe o ka uhi. Hoʻonui ka maʻemaʻe kiʻekiʻe o ka uhi i kāna hana. No ka laʻana, hiki i ka pulse silver plating ke hoʻomaikaʻi nui i ka weldability, conductivity, color resistance, a me nā waiwai ʻē aʻe, a he waiwai nui ia i ka pūʻali koa, electronics, aerospace, a me nā kahua ʻē aʻe.
4. ʻOi aku ka wikiwiki o ka sedimentation
Manaʻo paha kekahi poʻe he haʻahaʻa ka nui o ka hoʻopili ʻana o ka pulse electroplating ma mua o ka electroplating o ke au pololei ma muli o ke alo o kahi manawa pio. ʻOiaʻiʻo, ʻaʻole like ia me ia. Aia ka nui o ka sedimentation ma ka huahana o ka nui o ke au a me ka pono o ke au. Ma lalo o nā nui o ke au awelika like, ʻoi aku ka wikiwiki o ka hoʻopili ʻana o ka pulse electroplating ma muli o ka hoʻihoʻi ʻana o ka nui o ka ion ma ka ʻāpana cathode i ka wā pio, e hopena ana i ka pono o ke au kiʻekiʻe. Hiki ke hoʻohana ʻia kēia hiʻohiʻona i ka hana electroplating hoʻomau e pono ai ka hoʻopili wikiwiki ʻana, e like me nā uea uila.
ʻOiaʻiʻo, ma waho aʻe o nā noi i ʻōlelo ʻia ma luna, me ka holomua o ka ʻenehana, ke hoʻonui mau nei nā lako mana pulse i kā lākou noi ma nā kahua e like me ka nanoelectrodeposition, anodizing, a me ka hoʻōla electrolytic. No ka electroplating maʻamau, ʻo ka hoʻololi ʻana i ka pulse electroplating wale nō no ka hoʻomaikaʻi ʻana i ka pono hana ʻaʻole paha he mea waiwai.
