Tungsten carbide hard alloy adapangidwa makamaka kuti asawononge dzimbiri, abrasion, kuvala, kukhumudwa, kuvala kotsetsereka komanso kukhudza zida zam'mphepete mwa nyanja ndi m'mphepete mwa nyanja komanso pamwamba ndi pansi panyanja.

Tungsten carbide ndi mankhwala achilengedwe omwe ali ndi ma atomu a tungsten ndi carbon. Tungsten carbide, yomwe imadziwikanso kuti "simenti carbide", "yolimba aloyi" kapena "hardmetal", ndi mtundu wa zinthu metallurgic zomwe muli tungsten carbide ufa (mankhwala chilinganizo: WC) ndi binder zina (cobalt, faifi tambala. etc.). akhoza kupsinjidwa ndi kupangidwa mwamakonda, akhoza kupukutidwa mwatsatanetsatane, ndipo akhoza kuwotcherera kapena kumezetsanidwa ku zitsulo zina. Mitundu yosiyanasiyana ndi magiredi a carbide amatha kupangidwa monga momwe amafunikira kuti agwiritsidwe ntchito, kuphatikiza mafakitale amafuta, mafuta & gasi ndi zam'madzi monga zida zamigodi ndi zodulira, nkhungu ndi kufa, zida zovala, ndi zina zambiri.

Tungsten carbide inlet mbale amagwiritsidwa ntchito kwambiri pamayendedwe a pulser a WMD&LWD system.

Tungsten carbide pobowola MWD/LWD imaphatikizapo mitundu iwiri: Thupi lalikulu ndi gawo la ulusi amapangidwa ndi tungsten carbide, yomwe imatchedwa mutu wa valve yolimba ya alloy; Thupi lalikulu ndi tungsten carbide ndipo gawo la ulusi limapangidwa ndi zosapanga dzimbiri. zitsulo (monga zitsulo zosapanga dzimbiri 304, etc) zomwe zimatchedwa welded main vavu mutu.
