IINDABA

I ezahlukeneyo impahlas yemivalo yokuvuthelazixhomekekekwimivalo yokubetha ngokwayo,leyo unakomazenziwe ngentsimbi yemanganese, intsimbi yolwakhiwo lwe-martensitic (intsimbi ye-martensitic), intsimbi yekhrom, okanye imidibaniso yesinyithi yematrix (MMC, efana ne-ceramic).Ii-MMCs zenziwe ngeentlobo ezahlukeneyo zentsimbi kunye neentlobo ezikhethekileyo zeceramic.

Njengoko ukunyanzeliswa kokugqoka (ubunzima) bezinto zetsimbi kwanda, ukuqina (ukuchasana kwempembelelo) kuya kuncipha ngokuqhelekileyo.

I yokuqala ubulukhuniyemanganeseintsimbi yimalunga200 HV (20 HRC,ngokutshokwi Rockwellubulukhuni uvavanyo), and yayoimpembeleloamandla yimalunga250 J/cm2.Emva kokoumsebenziukuqina, iyokuqala ubulukhuni Nyusas ukuyaukusebenza ubulukhuni leyoyimalunga500 HV (50 HERC), ngelixaiNzulu kakhulu iziko inxalenyenangokuuhlalaikulungile ubunzimayeintsimbi impahla ukusukelaayiyolukhunied.Iubukhulu and iubulukhuniyehayik-lukhuniumaleko zixhomekekes kwiisicelokwaye iuhloboyemanganese intsimbi.Iubukhuluyenzimanedumalekoyimalunga10 mm.
