ʻO ke kaʻina hana o ka papa galvanized wela ka hana o ka hana ʻana i ka hao-zinc alloy ma waena o ka matrix hao a me ka papa zinc maʻemaʻe waho.Hoʻokumu ka ʻili o ka mea hana i ka ʻāpana hao-zinc i ka wā o ka hoʻoheheʻe wela, i hui maikaʻi ʻia ka hao a me ka papa zinc maʻemaʻe.Hiki ke wehewehe wale ʻia ke kaʻina hana o ka uea uʻi ʻōwili nui: i ka wā e hoʻoheheʻe ʻia ai ka mea hana hao i loko o ka solution zinc i hoʻoheheʻe ʻia, ua hoʻokumu ʻia ka zinc mua a me ka α-hao (kūpono i ke kino) hoʻoheheʻe paʻa ma ka interface.He aniani kēia i hana ʻia e ka hao matrix i hoʻoheheʻe ʻia me nā ʻātoma zinc i ke kūlana paʻa.Hoʻohui ʻia nā ʻātoma metala ʻelua me kekahi, a liʻiliʻi ka huki ʻana ma waena o nā ʻātoma.
No laila, i ka hiki ʻana o ka zinc i ka saturation i ka hoʻoheheʻe paʻa, hoʻopuehu ʻia nā mea ʻelua o ka zinc a me nā ʻātoma hao kekahi i kekahi, a hoʻopuehu ʻia nā ʻātoma zinc i loko (a i hoʻokomo ʻia i loko) o ka matrix hao e neʻe i loko o ka lattice o ka matrix a puka mālie. he huila me ka hao, oiai ka hao i hooleleia iloko o ka wai kinikini hehee e hana ana i mea hui waena FeZn13 me ka zinc a komo iloko o ka ipu hao wela, oia hoi ka zinc slag.Ke hoʻoneʻe ʻia ka mea hana mai ka hopena zinc leaching, ua hoʻokumu ʻia ka ʻili o ka papa zinc maʻemaʻe, ʻo ia ke aniani hexagonal, a ʻaʻole ʻoi aku ka nui o ka hao ma mua o 0.003%.
ʻO ka galvanizing wela wela, ʻike ʻia hoʻi ʻo ka hot dip galvanizing, ke ʻano o ka loaʻa ʻana o kahi uhi metala ma o ka hoʻokomo ʻana i kahi lālā kila i loko o kahi solution zinc molten.Me ka hoʻomohala wikiwiki ʻana o ka hoʻoili uila kiʻekiʻe, ka lawe ʻana a me ke kamaʻilio ʻana, ʻoi aku ka kiʻekiʻe o nā koi palekana no nā ʻāpana kila, a ke piʻi nei hoʻi ke koi no ka hot-dip galvanizing.ʻO ka maʻamau ka mānoanoa o ka papa uʻi uila he 5 ~ 15μm, a ʻoi aku ka nui o ka uea uʻi ʻōwili nui ma mua o 35μm, a hiki i 200μm.Loaʻa i ka galvanizing wela ka hiki ke uhi maikaʻi, ka uhi paʻa a ʻaʻohe mea hoʻohui.
