I-Tungsten carbide hard alloy iklanyelwe ngokukhethekile ukumelana nokugqwala, ukuhuzuka, ukuguga, ukuguga, ukuguga okuslayidayo futhi ibe nomthelela kokubili ogwini nasogwini kanye nezicelo zemishini yangaphezulu nengaphansi kolwandle.

I-Tungsten carbide iyinhlanganisela yamakhemikhali angaphili equkethe izinombolo ze-tungsten nama-athomu e-carbon. I-Tungsten carbide, eyaziwa nangokuthi "i-cemented carbide", "i-alloy eqinile" noma "i-hardmetal", iwuhlobo lwempahla ye-metallurgic equkethe i-tungsten carbide powder (ifomula yamakhemikhali: WC) kanye nezinye i-binder (cobalt, nickel. njll.). ingacindezelwa futhi yakheke ibe yizimo ezenziwe ngokwezifiso, ingagaywa ngokunemba, futhi ingashiselwa noma ixhunywe kwezinye izinsimbi. Izinhlobo ezahlukahlukene namamaki e-carbide angaklanywa njengoba kudingwa ukuthi asetshenziswe ekusetshenzisweni okuhlosiwe, okuhlanganisa imboni yamakhemikhali, uwoyela negesi nezasolwandle njengamathuluzi okumba nokusika, isikhunta nokufa, izingxenye zokugqoka, njll.

Ipuleti le-Tungsten carbide inlet lisetshenziswa kabanzi ukunyakaza kwe-pulser ye-WMD&LWD system.

I-Tungsten carbide yokubhoboza i-MWD/LWD ihlanganisa izinhlobo ezimbili: Umzimba oyinhloko kanye nengxenye ecushiwe yenziwe nge-tungsten carbide, ebizwa ngokuthi i-overall hard alloy main valve head; Umzimba oyinhloko yi-tungsten carbide kanti ingxenye ye-threader yenziwe nge-stainless. insimbi(njengensimbi engagqwali 304, njll) ebizwa ngekhanda levalvu eshiselwe.
