Ubudlelwane phakathi koBulukhuni kunye nokuNxitywa kweTungsten Carbide

Ukumelana nokunxiba kubhekisa kumandla okumelana nokungqubana, kwaye i-tungsten carbide, into esetyenziswa kakhulu, inokumelana nokunxiba okuphezulu. Yintoni ubudlelwane phakathi kobunzima kunye nokumelana nokunxiba kwe-tungsten carbide?

Ngokubanzi, okukhona ubulukhuni buphezulu, kokukhona ukuxhathisa ukunxiba ngcono. Amancinci amancinci ensimbi ye-tungsten anayo, ukuphakama kobunzima kunye nokumelana nokunxiba okungcono. Ukumelana nokunxiba kwe-carbide ene-cemented kuhambelana nenxalenye equlethwe yi-titanium carbide kunye ne-cobalt carbide. Kuya kuba bubunzima obuphezulu kunye nokumelana nokunxiba okungcono, kunye ne-titanium carbide kunye ne-cobalt encinci.

I-tungsten carbide inokufikelela kwi-86 HRA ukuya kwi-94 HRA kwiqondo lokushisa, elilingana ne-69 ukuya kwi-81HRC. Ubulukhuni obuphezulu bunokugcinwa kwi-900 ukuya kwi-1000 ° C kunye nokumelana nokunxiba okugqwesileyo. I-carbide ene-cemented yenziwe ngoluhlu lwee-carbides zetsimbi ezichasayo ezifana ne-WC, i-TiC, i-NBC, kunye ne-Vc kunye ne-powder metallurgical method njenge-binder. Xa kuthelekiswa nesixhobo esinzima kakhulu, inokuqina okuphezulu. Xa kuthelekiswa nentsimbi yesantya esiphezulu, inobunzima obuphezulu kwaye inxibe ukuxhathisa.

Ukuqina luphawu olubalulekileyo lomsebenzi wokulinganisa izinto zetsimbi, oku kukwazi kwesixhobo ukuxhathisa i-elastic deformation, ukuguqulwa kweplastiki kunye nomonakalo. Ukuba ezinye izinto azizange ziqwalaselwe, ubudlelwane phakathi kobunzima kunye nokuxhatshazwa kokugqoka kukuba ukuphakama kobunzima, bhetele ukuxhatshazwa kokugqoka. Isixhobo esifanayo sinonyango olwahlukileyo lomphezulu, kwaye ubunzima bulingana nokunxiba ukuxhathisa.

Nangona kunjalo, izinto eziphathekayo ezinokumelana nokunxiba kakuhle zingenakho ubunzima obuphezulu. Umzekelo, ukuqina kwentsimbi ekhatywayo eyona nto ixhaphakileyo yokunxiba ayiphezulu.

Ubunzima obuphezulu kunye nokumelana nokugqwesa okugqwesileyo yimfuneko esisiseko. Ngokwenkqubo ekhethekileyo yokuvelisa iinxalenye ze-carbide, i-ZZBETTER iyamkela inkqubo ye-HIP yobugcisa. Xa indawo engenanto ifakwe kwimilo, intambo yangaphakathi ibunjwa ngokuchaneka kwesiqingatha, nto leyo ilungele ukugqibezela okulandelelweyo okuchanekileyo. Oku kunamandla kakhulu kwi-tungsten carbide blank sintering kwaye ilawula ngokuchanekileyo ukuchaneka komgangatho weendawo zokunxiba ze-carbide.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
