ʻO Ferroboron kahi hao hao i haku ʻia me ka boron a me ka hao, i hoʻohana nui ʻia i ke kila a me ka hao.ʻO ka hoʻohui ʻana i ka 0.07%B i ke kila hiki ke hoʻomaikaʻi nui i ka paʻakikī o ke kila.Hoʻohui ʻia ʻo Boron i 18% Cr, 8% Ni stainless steel ma hope o ka mālama ʻana e hiki ke hoʻoikaika i ka ua, hoʻomaikaʻi i ka ikaika wela a me ka paʻakikī.ʻO Boron i loko o ka hao hao e hoʻopili i ka graphitization, no laila e hoʻonui ai i ka hohonu o ka puka keʻokeʻo e paʻakikī a paʻa i ka lole.ʻO ka hoʻohui ʻana i ka 0.001% ~ 0.005% boron i ka hao hoʻoheheʻe malleable he mea pono i ka hana ʻana i ka inika spheroidal a me ka hoʻomaikaʻi ʻana i kāna hāʻawi ʻana.I kēia manawa, ʻo ka alumini haʻahaʻa a me ka boron hao kalapona haʻahaʻa ka mea kumu nui no nā alloys amorphous.Wahi a GB5082-87 maʻamau, ua hoʻokaʻawale ʻia ka boron hao o Kina i ke kalapona haʻahaʻa a me ke kalapona waena ʻelua mau ʻāpana o 8 mau papa.ʻO Ferroboron kahi huila multicomponent i haku ʻia me ka hao, boron, silicon a me alumini.
ʻO ka ferric boron he deoxidizer ikaika a me ka mea hoʻohui boron i ka hana kila.ʻO ka hana o ka boron i ke kila ka mea e hoʻomaikaʻi nui ai i ka hardenability a hoʻololi i ka nui o nā mea hoʻohuihui me ka liʻiliʻi loa o ka boron, a hiki nō hoʻi ke hoʻomaikaʻi i nā waiwai mechanical, nā waiwai deformation anu, nā waiwai welding a me nā waiwai wela kiʻekiʻe.
E like me ka kalapona maʻiʻo o ka boron hao hiki ke maheleia i haʻahaʻa kalapona papa a me medium kalapona papa elua waeʻano, pakahi no ka like 'ole o ke kila.Ua helu 'ia ka haku mele 'ana o ka ferric boron ma ka Papa 5-30.Hana ʻia ka haʻahaʻa kalapona hao boride ma ke ʻano thermit a loaʻa iā ia kahi mea alumini kiʻekiʻe.Hoʻokumu ʻia ka hao boron kalapona ma ke kaʻina silicothermic, me ka haʻahaʻa alumini haʻahaʻa a me ke kalapona kiʻekiʻe.Ma lalo iho nei e hoʻolauna i nā kumu nui a me ka mōʻaukala o ka hoʻohana ʻana i ka boron hao.
ʻO ka mea mua, nā kumu nui o ka hoʻohana ʻana i ka boron hao
I ka hoʻohana ʻana i ka hao boride, pono e hoʻomaopopo ʻia kēia mau mea:
1. ʻAʻole like ka nui o ka borona i loko o ka borona hao, a ua nui loa ka ʻokoʻa.ʻO ka hakina boron i hāʻawi ʻia ma nā pae maʻamau mai 2% a 6%.I mea e hoʻomalu pono ai i ka ʻike o ka boron, pono e hoʻoheheʻe ʻia i loko o ka umu induction vacuum ma mua o ka hoʻohana ʻana, a laila hoʻohana ʻia ma hope o ka nānā ʻana;
2. E koho i ka papa kūpono o ka hao boride e like me ke kila hoohehee.I ka hoohehee ana i ke kila kuhilihi ki'eki'e no na mea kanu nukili, pono ke koho 'ia ke kalapona ha'aha'a, alumini ha'aha'a, hao boron ha'aha'a phosphorus.I ka hoohehee ana i ke kila kila kila, hiki ke koho i ka hao boride kalapona kalapona;
3. Ua emi ka helu o ka ho'iho'i 'ana o ka borona i loko o ka hao hao me ka ho'onui 'ia o ka borona.No ka loaʻa ʻana o ka helu hoʻōla ʻoi aku ka maikaʻi, ʻoi aku ka maikaʻi o ke koho ʻana i ka hao hao me ka haʻahaʻa o ka boron.
ʻO ka lua, ka moʻolelo o ka boron hao
ʻO David British (H.Davy) no ka manawa mua e hana i ka boron ma o ka electrolysis.Ua hana ʻo H.Moissan i ka borate hao kalapona kiʻekiʻe i loko o ka umu ahi arc i ka makahiki 1893. I ka makahiki 1920 he nui nā patent no ka hana ʻana i ka hao boride.ʻO ka hoʻomohala ʻana o nā ʻāpana amorphous a me nā mea magnet mau loa i nā makahiki 1970 i hoʻonui i ka koi no ka hao boride.I ka hopena o nā makahiki 1950, ua hoʻomohala maikaʻi ka Keʻena ʻImi Hao a me Steel Research Institute o Kina ma ka hana thermit.Ma hope iho, ʻo Jilin, Jinzhou, Liaoyang a me nā hana nui ʻē aʻe, ma hope o 1966, ʻo ka hana nui ʻo Liaoyang.I ka makahiki 1973, ua hana ʻia ka boron hao e ka umu uila ma Liaoyang.I ka makahiki 1989, ua hoʻomohala ʻia ka hao alumini-boron haʻahaʻa e ke ʻano umu uila.
