1. ʻO kauhi hoʻoheheʻe hakahakaʻO ke kaʻina hana e komo pū ana me ka mahu ʻana o nā mea ʻiliʻili, ka lawe ʻana o nā ʻātoma mahu i ka hakahaka kiʻekiʻe, a me ke kaʻina hana o ka nucleation a me ka ulu ʻana o nā ʻātoma mahu ma luna o ka ʻili o ka mea hana.
2. Kiʻekiʻe ke kiʻekiʻe o ka hoʻokahe ʻana o ka uhi ʻana i ka vacuum, ma ke ʻano he 10-510-3Pa. ʻO ke ala manuahi o nā molekala kinoea he 1 ~ 10m ke kauoha o ka nui, ʻoi aku ka nui ma mua o ka mamao mai ke kumu mahu a i ka workpiece, ua kapa ʻia kēia mamao ʻo ka mamao mahu, ma ke ʻano maʻamau he 300 ~ 800mm. ʻAʻole paʻakikī ke kuʻi ʻana o nā ʻāpana uhi me nā molekala kinoea a me nā ʻātoma mahu a hiki i ka workpiece.
3. ʻAʻole i uhi ʻia ka papa uhi hoʻoheheʻe hakahaka, a hele pololei nā ʻātoma mahu i ka workpiece ma lalo o ka vacuum kiʻekiʻe. ʻO ka ʻaoʻao wale nō e kū pono ana i ke kumu hoʻoheheʻe ma ka workpiece hiki ke loaʻa ka papa kiʻiʻoniʻoni, a ʻo ka ʻaoʻao a me ke kua o ka workpiece hiki ʻole ke loaʻa ka papa kiʻiʻoniʻoni, a he uhi maikaʻi ʻole ka papa kiʻiʻoniʻoni.
4. Haʻahaʻa ka ikehu o nā ʻāpana o ka papa uhi hoʻoheheʻe hakahaka, a ʻo ka ikehu e hiki ana i ka mea hana, ʻo ia ka ikehu wela i lawe ʻia e ka hoʻoheheʻe ʻana. ʻOiai ʻaʻole i hoʻopilikia ʻia ka mea hana i ka wā o ka uhi hoʻoheheʻe hakahaka, hilinaʻi wale nā ʻātoma metala i ka wela o ka vaporization i ka wā o ka hoʻoheheʻe ʻana, ʻo ka mahana hoʻoheheʻe he 1000 ~ 2000 °C, a ua like ka ikehu i lawe ʻia me 0.1 ~ 0.2eV, no laila haʻahaʻa ka ikehu o nā ʻāpana kiʻiʻoniʻoni, liʻiliʻi ka ikaika hoʻopaʻa ma waena o ka papa kiʻiʻoniʻoni a me ka matrix, a he paʻakikī ke hana i kahi uhi hui.
5. He ʻano maikaʻi ko ka papa uhi hoʻoheheʻe hakahaka. Hoʻokumu ʻia ke kaʻina hana uhi hoʻoheheʻe hakahaka ma lalo o ka hakahaka kiʻekiʻe, a ʻo nā ʻāpana kiʻiʻoniʻoni i loko o ka mahu he ʻano atomika ia, e hana ana i kahi ʻiʻo maikaʻi ma luna o ka ʻili o ka mea hana.
