Indlela Yokukhiqiza I-Carbide Substrate Ye-PDC Cutters

Abasiki be-PDC basetshenziswa kakhulu ezimbonini zezimayini, zikawoyela, nezegesi. Njengoba sazi, ukwakheka komsiki we-PDC kuqukethe izingxenye ezimbili, enye iyisendlalelo sedayimane, kanti enye i-substrate ye-carbide. Abasiki be-PDC bahlangana nedayimane ngobulukhuni obuphezulu kanye ne-carbide substrate ekumelaneni nomthelela. I-PDC cutter yekhwalithi ephezulu ayidingi nje ubuchwepheshe obuhle kuphela, kodwa futhi nempahla eluhlaza ye-premium. I-substrate ye-carbide idlala indima ebalulekile kuyo. Namuhla singathanda ukwabelana ngokuthi i-substrate ye-carbide yenziwa kanjani.

I-carbide enosimende (i-tungsten carbide) iyimpahla eqinile eyenziwe yizinhlayiya ezinhle ze-carbide ezifakwe kwinhlanganisela ngensimbi ebophayo. I-Cemented Carbides ithola ubulukhuni bawo ezinhlamvini ze-Tungsten Carbide kanye nokuqina kwayo kusukela ekuhlanganisweni okukhiqizwa isenzo sokuhlanganisa sensimbi ye-Cobalt. Ngokushintsha inani le-Cobalt, singashintsha ubulukhuni, ukumelana nokugqokwa, kanye nokuqina (ukushaqeka noma ukumelana nomthelela) kwe-carbide ukuze sikunikeze ukusebenza okuphezulu kohlelo lwakho lokusebenza oluthile. Ibanga le-carbide le-PDC cutter substrate liyahluka ukusuka ku-YG11 kuye ku-YG15.

Inqubo yokukhiqiza eyinhloko ye-carbide substrate imi kanje:

Ifomula mayelana nebanga: Okokuqala, i-WC powder, i-cobalt powder, nezici ze-doping zizoxutshwa ngokuvumelana nefomula evamile ngezithako ezinolwazi. Isibonelo, ebangeni lethu le-UBT20, kuzoba ngu-10.2% Cobalt, futhi ibhalansi i-WC powder kanye nezici ze-doping.

Impushana emanzi yokugaya: I-WC powder exutshwe, i-cobalt powder kanye nezakhi ze-doping zizofakwa emshinini wokugaya omanzi. Ukugaya ibhola elimanzi kuzohlala amahora angu-16-72 mayelana nobuchwepheshe obuhlukahlukene bokukhiqiza.

Ukomisa impushana: Ngemva kokugaya, impushana izofuthwa yomiswe ukuze uthole impushana eyomile noma i-granulate. Uma indlela yokwenza i-extrusion, i-powder ehlanganisiwe izophinde ihlanganiswe ne-Adhesive.

Ukucindezela isikhunta: Le ngxube ye-powder ifakwe esikhunjini futhi icindezelwe ngokucindezela okukhulu ekubunjweni.

I-Sintering: Cishe ku-1380 ℃, i-cobalt izogeleza ezindaweni zamahhala phakathi kwezinhlamvu ze-tungsten carbide. Isikhathi se-sintering cishe amahora angama-24 kuye ngamamaki namasayizi ahlukene.

I-ZZbetter inokulawula okuqinile kwezinto ezingavuthiwe ze-diamond grit ne-carbide substrate. Kungakho singakukhiqizela izisiki ze-PDC zekhwalithi ephezulu.

I-ZZbetter inobubanzi obugcwele bosayizi bezisiki ze-PDC ozikhethayo. Ukulethwa okusheshayo phakathi kwezinsuku ezingu-5 ukuze wonge isikhathi sakho. I-oda lesampula lamukelekile ukuthi lihlolwe. Lapho udinga ukuvuselela i-drill bit yakho, i-ZZbetter ingakunikeza isisiki se-PDC ngokushesha nje.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma nge-imeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
