Eyona nto iNxitywayo iTungsten Carbide

Njengoko sonke sisazi, incinci isayizi yengqolowa ye-tungsten carbide, iphakamisa ubulukhuni bayo kunye nokumelana nokunxiba. Nangona kunjalo, ngaba uyazi ukuba yeyiphi eyona tungsten carbide enganyangekiyo? Kweli nqaku, siza kuthetha nge-tungsten carbide eyona nto inxibayo.

Ngokobunzima obahlukeneyo, i-tungsten carbide inokwahlulwa ibe ziindidi ezininzi zamabakala, njengeYG8, YG15, njalo njalo. Iimveliso ze-tungsten ze-carbide zenziwe nge-powder metallurgy, esebenzisa i-tungsten carbide njengeyona nto iphambili ekrwada, kwaye iyixube kunye ne-binder powder. Emva kokuxuba, i-tungsten carbide powder kunye ne-binder powder iya kugatywa, yomiswe, icinezelwe, kwaye ifakwe. Ngokuqhelekileyo, inani le-tungsten lingaphezulu kwe-80%.

Ukumelana nokunxiba kwe-tungsten carbide kugqitywe ngobukhulu bayo beenkozo kunye nesixa se-cobalt. Ubuncinci ubungakanani bengqolowa kunye nexabiso eliphantsi le-cobalt, kokukhona ukuqina kwe-tungsten carbide. Ngoko xa ukhetha imveliso ye-tungsten carbide, sinokuqwalasela ubunzima bayo, imfuno kunye nesicelo. Ngelixa ukusebenza kwempembelelo rhoqo ngexesha lomsebenzi, kufuneka siqwalasele ukuxhathisa.

Xa sithetha malunga nokuba zeziphi iimveliso ze-tungsten ze-carbide zezona zinxibayo, okokuqala, kufuneka sicinge ngemeko. Ngokuqhelekileyo, i-tungsten carbide inokwahlulwa ibe ngamacandelo amathathu.

1. I-YG: Uchungechunge lwe-YG lwenziwe nge-tungsten carbide powder njengento ekrwada kunye ne-cobalt powder njengesibophelelo sayo. Iimveliso ze-tungsten ze-carbide ezenziwe kuluhlu lwe-YG zinokuxhathisa okulungileyo, ukuxhathisa ukunxiba, kunye ne-thermal conductivity kwaye zisetyenziswa ngokubanzi ukwenza isinyithi esityhidiweyo kunye nesinyithi esingenawo i-ferrous.

2. I-YT: Uchungechunge lwe-YT lwenziwe nge-tungsten carbide powder kunye ne-cobalt powder, kunye nenye i-TiC powder. I-TiC inokongezwa ukuphucula ukuxhathisa ukunxiba kweemveliso ze-tungsten carbide kunye nokunciphisa ukuqina kokugoba. Olu hlobo lwemveliso ye-tungsten carbide inobunzima obuphezulu, ukumelana nobushushu obuphezulu, kunye nokumelana ne-oxidation kwaye ifanelekile kwintsimbi yokuvelisa.

3. I-YW: Uchungechunge lwe-YW lwenziwe nge-tungsten carbide powder, i-cobalt powder, i-TiC, kunye ne-TaC. I-TaC yongezwa ukuphucula amandla kunye nokuxhathisa kweemveliso ze-tungsten carbide. Ezi ntlobo zeemveliso ze-tungsten ze-carbide zifanelekile ukwenza i-alloy steels ephezulu, i-alloys ekwazi ukumelana nobushushu, kunye nentsimbi.

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