Zobowola zitsulo zapamwamba kwambiri, zothamanga kwambiri nthawi zambiri zimawonekera zoyera.Zoonadi, tinthu tating'onoting'ono tobowola tithanso kukhala zoyera pogaya bwino bwalo lakunja.Chifukwa chomwe ndipamwamba kwambiri ndikuti kuwonjezera pa zinthu zomwezo, kuwongolera kwabwino pa nthawi yopera kumakhala kolimba kwambiri, sipadzakhala zoyaka pamwamba pa chida.Black ndi kubowola pang'ono kuti wakhala nitrided.
Ndi njira yamankhwala yomwe imayika chida chomalizidwa mu chisakanizo cha ammonia ndi nthunzi yamadzi ndikuchiwotcha pa 540 ~ 560 ° C kuti chikhale cholimba cha chida. mumtundu (kuti aphimbe kutentha kapena khungu lakuda pamwamba pa chida), koma zotsatira zenizeni zogwiritsira ntchito sizinapangidwe bwino.
Pali njira zitatu zopangira zobowola, wakuda ndikugudubuza, woyipa kwambiri.Zoyera zimadulidwa ndikupukutidwa.Chifukwa sichimapanga oxidation yotentha kwambiri, mosiyana ndi kugubuduza, kapangidwe kake kachitsulo sikuwonongeka.Amagwiritsidwa ntchito pobowola zida zogwirira ntchito zolimba pang'ono.Kubowola kwachikasu-bulauni kumatchedwa kuti cobalt-containing drill mu industry.Ili ndilo lamulo losamveka la makampani obowola.Ma diamondi okhala ndi cobalt poyamba amakhala oyera ndipo amapangidwa ndi kugaya.Pamene atomu m’kupita kwanthaŵi, amasanduka achikasu abulauni (omwe nthaŵi zambiri amatchedwa amber), amene pakali pano ndiwo amafalitsidwa kwambiri.M35 (Co 5%) ilinso ndi mtundu wa golide.
Kubowola kotereku kumatchedwa titaniyamu-plated drill, yomwe imagawidwa m'mapangidwe okongoletsera ndi mafakitale.Chophimba chokongoletsera sichimakhudza nkomwe, ndi chokongola komanso chagolide.Kuyika kwa mafakitale ndikwabwino kwambiri, kuuma kumatha kufikira HRC78, komwe ndikwapamwamba kuposa kuuma kwa diamondi yokhala ndi cobalt (HRC54).
