Izici:
Inombolo yezimbobo ezinezintambo zezingcezu zesampula zokucubungula ezifanele zincane, ukucaciswa kwentambo kuningi, ukusetshenziswa kulula, ukumelana nokucubungula intambo eyodwa kuncane, futhi izimbobo ezijulile ezinezintambo zingacutshungulwa.I-DLC enemibala eyisikhombisa ine-coefficient ephansi yokungqubuzana kanye nokumelana okuphezulu nokuhlangana nokugqwala kwezinsimbi ezingenayo insimbi.
Inzuzo:
I-Nano coating, Cabangela ubulukhuni nokumelana nokugqoka.
Khetha kahle izinti zensimbi ze-tungsten ,Iqinisiwe futhi iqinile,Ukuqina okuphezulu, Yamukela amabha ensimbi ekhwalithi ephezulu ye-tungsten,Ukuqina okuphezulu nokumelana nokugqokwa, kuyilapho uthuthukisa impilo yesevisi yethuluzi.
