Izinto ezisetshenziswa ekwenziweni kweizitembu zokunyathelakufaka phakathi insimbi, i-carbide eqinisiwe ngensimbi, i-carbide, ama-alloy asekelwe ku-zinc, izinto ze-polymer, ithusi le-aluminium, ama-alloy aphansi naphezulu okuncibilika njalo njalo. Izinto eziningi ezisetshenziswa ekwenziweni kwama-dies okunyathela ikakhulukazi yinsimbi. Izinhlobo ezivamile zezinto ezisetshenziselwa izingxenye zokusebenza zama-dies yilezi: insimbi yamathuluzi e-carbon, insimbi yamathuluzi e-alloy ephansi, insimbi yamathuluzi e-chromium ephezulu noma ephakathi, insimbi ye-alloy yekhabhoni ephakathi, insimbi yesivinini esikhulu, insimbi ye-matrix kanye ne-carbide, i-carbide eqinisiwe ngensimbi, njll.

1. Insimbi yamathuluzi e-alloy ephansi

Insimbi yamathuluzi e-alloy ephansi isekelwe ensimbini yamathuluzi e-carbon ngokwengeza inani elifanele lezinto zokuhlanganisa. Uma kuqhathaniswa nensimbi yamathuluzi e-carbon, kunciphisa ukuthambekela kokuqhekeka nokuguqulwa kokucima, kuthuthukisa ukuqina kwensimbi, ukumelana nokuguguleka nakho kungcono. Insimbi e-alloy ephansi esetshenziswa ekwenziweni kwezikhunta yi-CrWMn, 9Mn2V, 7CrSiMnMoV (ikhodi CH-1), 6CrNiSiMnMoV (ikhodi GD) njalo njalo.

2. Insimbi yamathuluzi ekhabhoni

Ukusetshenziswa okwengeziwe ekubunjweni kwensimbi yamathuluzi ekhabhoni ye-T8A, T10A, njll., izinzuzo zokusebenza kahle kokucubungula, kushibhile. Kodwa ukuqina nokuqina okubomvu kubi, ukuguqulwa kokwelashwa kokushisa, umthamo ophansi wokuthwala umthwalo.

3. Insimbi yesivinini esikhulu

Insimbi yesivinini esiphezulu inobulukhuni obuphezulu kakhulu, ukumelana nokuguguleka kanye namandla okucindezela ensimbi yesikhunta, amandla aphezulu okuthwala umthwalo. Okuvame ukusetshenziswa ezikhumbeni yi-W18Cr4V (ikhodi 8-4-1) kanye ne-tungsten encane i-W6Mo5Cr4V2 (ikhodi 6-5-4-2, uhlobo lwase-United States i-M2) kanye nokuthuthukisa ukuqina kokuthuthukiswa kwensimbi yesivinini esiphezulu i-vanadium encishisiwe i-6W6Mo5Cr4V (ikhodi 6W6 noma i-M2 ephansi yekhabhoni). Izinsimbi zesivinini esiphezulu nazo zidinga ukufakelwa kabusha ukuze kuthuthukiswe ukusatshalaliswa kwazo kwe-carbide.

4. Izinsimbi zamathuluzi ze-chromium eziphakathi nendawo ezinekhabhoni ephezulu

Izinsimbi zamathuluzi ze-chromium eziphakathi nendawo ezinekhabhoni ephezulu ezisetshenziselwa isikhunta yi-Cr4W2MoV, Cr6WV, Cr5MoV, njll., okuqukethwe kwazo kwe-chromium kuphansi, i-carbide e-eutectic encane, ukusatshalaliswa kwe-carbide, ukuguqulwa kokwelashwa kokushisa kuncane, nokuqina okuhle kanye nokuqina kobukhulu. Uma kuqhathaniswa nokuhlukaniswa kwe-carbide, insimbi ye-chromium ephezulu enekhabhoni ephezulu ithuthukisiwe.

5. Insimbi yamathuluzi enekhabhoni ephezulu ene-chromium ephezulu

Insimbi yamathuluzi e-high-carbon high-chromium esetshenziswa kakhulu i-Cr12 kanye ne-Cr12MoV, i-Cr12Mo1V1 (ikhodi D2), inokuqina okuhle, ukuqina kanyeukumelana nokuguguleka, ukuguqulwa kokwelashwa kokushisa kuncane kakhulu, ngenxa yokumelana okuphezulu kokuguguleka kwensimbi encane, umthamo wokuthwala ulandela insimbi yesivinini esikhulu. Kodwa ukuhlukaniswa kwe-carbide kukhulu, kumele kuphazamiseke ngokuphindaphindiwe (ukuphazamisa kwe-axial, umdwebo we-radial) ukushintsha ukwakheka, ukuze kuncishiswe ukungalingani kwe-carbide, kuthuthukiswe ukusetshenziswa kwayo.

6. I-carbide esimende kanye ne-carbide esimende yensimbi

Ukuqina kanye nokumelana nokuguguleka kwe-carbide esimende kuphakeme kunokwanoma yiluphi olunye uhlobo lwensimbi yesimende, kodwa amandla okugoba kanye nokuqina akukuhle. I-carbide esimende esetshenziselwa izikhunta yi-tungsten ne-cobalt, futhi ezikhunta ezinezimfuneko ezincane zokumelana nokuguguleka okuphezulu, i-carbide esimende enezimfuneko ezincane ze-cobalt. Ezikhunta ezinezinzuzo eziphezulu, i-carbide equkethe i-cobalt ephezulu ingasetshenziswa.
