Hōʻike pinepine ʻia nā ʻāpana kila kiʻekiʻe kiʻekiʻe me ka lepo piha i ke keʻokeʻo.ʻOiaʻiʻo, hiki ke keʻokeʻo nā ʻāpana drill i ʻōwili ʻia ma ka wili maikaʻi ʻana o ka pōʻai waho.ʻO ke kumu o ke kiʻekiʻe kiʻekiʻe ʻo ia ka hoʻohui ʻana i ka mea ponoʻī, ʻoi aku ka paʻa o ka mana o ka maikaʻi i ka wā o ka wili ʻana, ʻaʻohe ahi ma ka ʻili o ka mea hana.ʻO ka ʻeleʻele kahi drill bit i nitrided.
He hana kemika ia e hoʻokomo i ka mea hana i hoʻopau ʻia i loko o ka hui ʻana o ka ammonia a me ka mahu wai a wela iā ia ma 540 ~ 560 ° C e hoʻomaikaʻi ai i ka lōʻihi o ka mea hana. i ke kala (i mea e uhi ai i ka wela a i ʻole ka ʻili ʻeleʻele ma ka ʻili o ka mea hana), akā ʻaʻole i hoʻomaikaʻi maikaʻi ʻia ka hopena hoʻohana maoli.
ʻEkolu mau kaʻina hana no ka hana ʻana i nā ʻāpana drill, ʻo ka ʻeleʻele ka ʻōwili, ʻoi aku ka ʻino.Hoʻokiʻoki ʻia nā mea keʻokeʻo a poni ʻia.No ka mea ʻaʻole ia e hoʻohua i ka oxidation wela kiʻekiʻe, ʻaʻole like me ka ʻōwili ʻana, ʻaʻole i hōʻino ʻia ke ʻano o ka palaoa o ke kila.Hoʻohana ʻia ia e wili i nā mea hana me ka ʻoi aʻe o ka paʻakikī.Kapaʻia ka pahu melemele-ʻeleʻeleʻo ka cobalt-containing drill i loko o kaʻoihana.He keʻokeʻo mua nā daimana Cobalt a hana ʻia ma ka wili ʻana.Ke ho'ātomized lākou i ka wā ma hope, lilo lākou i ʻeleʻele melemele (i kapa ʻia ʻo amber), ʻo ia ka mea maikaʻi loa i kēia manawa.He kala gula no ka M35 (Co 5%).
Kapa ʻia kēia ʻano drill he titanium-plated drill, i hoʻokaʻawale ʻia i ka plating decorative a me ka plating industrial.ʻAʻohe hopena o ka pāpale hoʻonaninani, nani a gula.He maikaʻi loa ka hoʻopili ʻana i ka ʻoihana, hiki i ka paʻakikī ke hiki i ka HRC78, ʻoi aku ka kiʻekiʻe ma mua o ka paʻakikī o nā daimana cobalt-containing (HRC54).
