ʻO ka pāpale hue waina Zinc alloy kahi ʻano o ka hoʻolei make me ka zinc ma ke ʻano nui.Aia ka ʻili o ka ʻili ma luna o ka ʻili o ka die casting, a i loko o ia mea he hale porous hāmama a me kahi metala amphoteric ola.No laila, ma ka hoʻohana ʻana i ke ʻano pretreatment kūpono a me ke kaʻina electroplating hiki iā mākou ke hōʻoia i ka hoʻopili maikaʻi ʻana o ka uhi electrodeposited o ka ʻōmole waina zinc alloy, e hoʻohālikelike ʻia i ke ʻano nani o ke kiʻi, a hoʻokō i nā koi o nā huahana kūpono.

Hoʻohana pinepine ʻia ʻo Za4-1 e like me ka zinc alloy material no ka electroplating, a ʻo kāna mau mea nui: Aluminum 3.5% ~ 4.5%, keleawe 0.75% ~ 1.25%, magnesium 0.03% ~ 0.08%, koena zinc, pau impurities ≤ 0.2%.ʻO ka 925 grade zinc alloy he mea keleawe kiʻekiʻe a maʻalahi ke hoʻopili ʻia.ʻO ka maʻamau, ʻo ka nui o ka zinc alloy he 6.4 ~ 6.5 g / cm.Inā ʻoi aku ka liʻiliʻi ma mua o 6.4 g / cm, maʻalahi ka blistering a me ka pitting ma hope o ka electroplating.I ka pōkole, pono e hoʻomalu ponoʻia ke kohoʻana i nā mea.Eia kekahi, pono e hoʻolālā kūpono i ka make make-casting e pale aku i nā hemahema hiki ʻole ke hoʻokō (e like me ka pitting) i ka electroplating.
