Tungsten Carbide Mabanga
Kana sarudzo yakanaka kwazvo, mashizha etungsten carbide ane saizi yesubmicron anogona kurodzwa kuita razor edge pasina kuputsika kwakajairika kunowanzobatanidzwa necarbide yemazuva ano. Kunyangwe isiri yakasimba sesimbi, carbide inodzivirira kupera simba zvakanyanya, ine kuomarara kwakaenzana neRc 75-80. Nguva yekushanda kwesimbi dzesimbi dzemazuva ano dzinosvika 50X inogona kutarisirwa kana simbi dzesimbi dzemazuva ano dzikadziviswa kupwanyika nekuputsika.
Sezvazvakaita pakusarudza simbi, kusarudza tungsten carbide (WC) ine giredhi rakakodzera inzira yakaoma inosanganisira sarudzo dzakakanganiswa pakati pekudzivirira kupera uye kusimba/kukunda kuvhunduka. Tungsten carbide yakagadzirwa ne sintering (pakupisa kwakanyanya) musanganiswa we tungsten carbide powder ne powdered cobalt (Co), simbi inonyunguduka inoshanda se "binder" ye tungsten carbide particles dzakaoma kwazvo. Kupisa kwe sintering process hakusanganisire kuita kwezvikamu zviviri izvi, asi kunoita kuti cobalt isvike padanho remvura uye ive se "encapsulating glue matrix" ye WC particles (iyo isingakanganiswi nekupisa). Ma parameter maviri, kureva chiyero cheCobalt neWC uye saizi ye WC particles, anodzora zvakanyanya hunhu hwezvinhu zvakawanda zve "cemented tungsten carbide" inobuda.
Kutsanangura saizi yakakura yeWC particles uye huwandu hwakawanda hweCobalt kuchapa chikamu chinodzivirira kuvhunduka zvakanyanya (uye simba guru rekurovera). Kana WC grain yakakura (saka, nzvimbo yakawanda yeWC inofanira kuputirwa neCobalt) uye Cobalt isingashandiswi zvakanyanya, chikamu chinobuda chichava chakaoma uye chisingaparare zvakanyanya. Kuti uwane kushanda kwakanakisa kubva kucarbide sechinhu chebanga, zvakakosha kudzivirira kutadza kwemucheto kusati kwasvika kunokonzerwa nekupwanyika kana kuputsika, ukuwo uchivimbisa kuramba kwakanyanya kupfeka.
Sezvineiwo, kugadzirwa kwemicheto yakapinza zvikuru, ine makona akajeka kunoreva kuti carbide yakanaka inofanira kushandiswa mukushandiswa kwemapanga (kuitira kudzivirira mavanga makuru nemicheto isina kurongeka). Tichifunga nezvekushandiswa kwecarbide ine avhareji yehukuru hwegrain ye1 micron kana pasi, mashandiro ebanga recarbide; saka, inonyanya kukanganiswa ne% yeCobalt uye geometry yemucheto yakatarwa. Kushandiswa kwekucheka kunosanganisira mitoro yepakati kusvika yakakwira kunoshandiswa zvakanyanya nekusarudza 12-15 muzana yeCobalt uye geometry yemucheto ine angle yemucheto inosvika 40º. Kushandiswa kunosanganisira mitoro yakareruka uye kunopa premium pahupenyu hwebanga refu kunokodzera carbide ine 6-9 muzana yecobalt uye ine angle yemucheto iri pakati pe30-35º.
HUAXIN CARBIDE yakagadzirira kukubatsira kuti uwane chiyero chakakodzera chezvinhu zvinokutendera kuti uwane kushanda kwakanyanya kubva kumablade ako ecarbide.
HUAXIN CARBIDE inopa sarudzo yemabhurazi ekuchekerera ecarbide ane razor
