Zviboorero zvesimbi zvemhando yepamusoro, zvakazara pasi pepamusoro-soro zvinowanzoonekwa muchena.Zvamazvirokwazvo, zvibooreso zvakakungurutswa zvinogona zvakare kuve zvichena nekukuya zvakanaka kwedenderedzwa rekunze.Chikonzero nei chiri chemhando yepamusoro ndechekuti mukuwedzera kune iyo pachayo, iyo yemhando yekudzora panguva yekugaya zvakare yakanyanya kuomarara, hapazove nekutsva pamusoro pechishandiso.Dema chibooreso chakaiswa nitrided.
Iyo ikemikari nzira inoisa chigadziro chakapedzwa mumusanganiswa weammonia nemhute yemvura uye inopisa pa 540 ~ 560 ° C kuti ivandudze kusimba kwechigadzirwa.Parizvino, mabheti akawanda ekuchera pamusika anongova madema. muvara (kuitira kuvhara kupisa kana ganda dema pamusoro pechishandiso), asi iyo chaiyo yekushandisa mhedzisiro haina kunyatso kuvandudzwa.
Kune matatu maitiro ekugadzira zvibooreso zvimedu, dema riri kukunguruka, rakaipisisa.Iwo machena anochekwa uye anokwenenzverwa.Nemhaka yokuti haibudisi yakakwirira-yekushisa oxidation, kusiyana nekukunguruka, chimiro chezviyo chesimbi hachina kukuvara.Inoshandiswa kudhiraivha maworkpiece nekuomarara zvishoma.Iyo yero-brown drill inodaidzwa kuti cobalt-containing drill muindasitiri.Uyu ndiwo mutemo usingataurwe weindastiri yekuchera iyi.Cobalt-ine madhaimondi pakutanga machena uye anogadzirwa nekukuya.Padzinenge dzave neatomu munguva inotevera, dzinoita yero yebrown (inowanzonzi amber), iyo ndiyo inonyanya kutenderera.M35 (Co 5%) zvakare ine ruvara rwegoridhe.
Mhando yedhiri iyi inonzi titanium-plated drill, iyo yakakamurwa kuita yekushongedza yekushongedza uye plating yeindasitiri.Iyo yekushongedza plating haina mhedzisiro zvachose, yakanaka uye yegoridhe.Indasitiri plating yakanaka kwazvo, kuoma kunogona kusvika HRC78, iyo yakakwira kupfuura kuomarara kwecobalt-ine madhaimondi (HRC54).
