Ke hoʻomau nei nā holomua i ka ʻenehana ʻenehana ikehu hou, e alakaʻi ana i ka hoʻololi ʻana i nā koi no nā ʻāpana kūkulu pākaukau.I kēia manawa, nui nā mea hana pākaukau lithium e wili ana i nā ʻāpana keleawe ma nā ʻāpana alumini e hoʻopili ai i nā electrodes pākahi.Ma nā ʻano hana kuʻuna, hoʻopaʻa ʻia ka wili maikaʻi ma waena o nā ʻāpana keleawe a me nā alumini e nā palena waiwai, a i ʻole ka hopena i ka hoʻopōmaikaʻi ʻole ʻana, lawa ʻole ka ikaika wili, a i ʻole nā kumukūʻai kiʻekiʻe.
I mea e hoʻokō ai i nā koi o ka mea kūʻai aku a me ka mākeke, ua hoʻohana ka hui ʻenehana ma Dongguan Mares i nā mea hoʻoheheʻe molecular e hoʻokō ai i ka wili ma waena o nā alumini a me nā ʻāpana keleawe.Hōʻike ʻia nā hopena wili ma ke kiʻi ma luna: maʻemaʻe ke ʻano, liʻiliʻi ke kuʻina weld, a kiʻekiʻe ka ikaika huki.Ua ʻae ʻia kēia huahana a ʻike ʻia e ka nui o nā mea kūʻai uila uila hou.
Hōʻike ka ʻenehana hoʻoheheʻe molecular diffusion i nā hopena maikaʻi loa ke hoʻohana ʻia i ka hapa nui o nā mea metala, ʻoi aku hoʻi i nā metala wili me ka conductivity thermal kiʻekiʻe e like me ke aluminika, nā alumini alumini, a me ke keleawe, e hōʻoia ana i ka maikaʻi a me ka hilinaʻi.
ʻO ke kuʻi ʻana ma waena o nā ʻāpana keleawe a me nā alumini ka mea kūpono no nā pilina alo-a-maka.Ma muli o ka reactivity kiʻekiʻe o ka alumini, ua maʻalahi ia i ka oxidation i ka wā o ke kaʻina hana.No laila, pono ka mana pololei o ka welding wela a me ka manawa e pale aku ai i ka distortion o nā ʻāpana keleawe-aluminika.
Hoʻomaʻemaʻe ma mua o ka welding:
Ma mua o ka hana ʻana i ka hoʻoheheʻe diffusion, pono e hoʻomaʻemaʻe ʻia nā mea hana me nā ʻaila ʻaila ma ka ʻili o nā ʻāpana keleawe-aluminika me nā mea hoʻoheheʻe organik a i ʻole nā huehu solvent organik (e like me ka acetone).Pono e hoʻomaʻemaʻe maikaʻi ʻia ka papa oxide i loko o kahi ākea 10mm o ka wahi hoʻoheheʻe me ka hoʻohana ʻana i ka sandpaper metallographic a i ʻole nā faila emery, ʻoi aku ka ʻili o loko o ka hui.
Kaʻina wiliwili:
He mea koʻikoʻi ka mālama ʻana i ka hoʻolikelike like ʻana o nā mea hana keleawe-aluminika i ke kūlana kūpono i loko o ke kaʻina diffusion molecular no ka hōʻoia ʻana i ka pololei kūpono.Hiki ke hoʻokō maʻamau me ka hoʻohana ʻana i nā mea hoʻonohonoho hoʻonohonoho, a i ʻole me ke kōkua ʻana o nā mea kōkua ʻē aʻe.ʻO ka helu ʻana i ka mahana wili a me ka manawa paʻa paʻa e pili ana i ka mānoanoa wili a me ka wahi pili o nā ʻāpana keleawe a me nā alumini he mea nui e pale i nā pilikia maikaʻi e like me ka deformation thermal.
