Ubwiza buhanitse, bwuzuye hasi bwihuta bwicyuma cyimyitozo ikunze kugaragara cyera.Birumvikana, kuzunguruka bitoboye birashobora kandi kuba umweru mugusya neza uruziga rwo hanze.Impamvu ituma iba nziza cyane nuko usibye ibikoresho ubwabyo, kugenzura ubuziranenge mugihe cyo gusya nabyo birakomeye, ntihazongera gutwikwa hejuru yigikoresho.Umukara ni imyitozo ya nitride.
Nuburyo bwa chimique bushyira igikoresho cyarangiye muruvange rwa ammonia hamwe numwuka wamazi hanyuma ukabishyushya kuri 540 ~ 560 ° C kugirango urusheho kuramba kwiki gikoresho. Kugeza ubu, ibyinshi mu bikoresho byirabura byirabura kumasoko birabura gusa mu ibara (murwego rwo gupfuka uruhu rwaka cyangwa umukara hejuru yigikoresho), ariko ingaruka zifatika ntizigeze zitezimbere neza.
Hariho uburyo butatu bwo gukora bits bits, umukara urazunguruka, mubi.Abazungu baratunganijwe kandi basizwe neza.Kuberako idatanga ubushyuhe bwo hejuru cyane, bitandukanye no kuzunguruka, imiterere yintete yicyuma ntabwo yangiritse.Byakoreshejwe gucukura ibihangano hamwe nuburemere buke buke.Imyitozo yumuhondo-umukara yitwa imyitozo ya cobalt irimo inganda.Aya ni itegeko ritavuzwe ryinganda zinganda.Diyama irimo Cobalt isanzwe yera kandi ikorwa no gusya.Iyo ziba atomome mugihe cyakurikiyeho, zihinduka umuhondo wumuhondo (muri rusange witwa amber), kuri ubu akaba ari mwiza mukuzenguruka.M35 (Co 5%) nayo ifite ibara rya zahabu.
Ubu bwoko bwimyitozo bwitwa titanium yashizwemo imyitozo, igabanijwemo isahani yo gushushanya no gutunganya inganda.Isahani yo gushushanya nta ngaruka namba ifite, ni nziza na zahabu.Isahani yinganda ninziza cyane, ubukana burashobora kugera kuri HRC78, iruta ubukana bwa diyama irimo cobalt (HRC54).
