Imyenge nyuma yo gucumura

Carbide ya sima ni ubwoko bwimvange igizwe na tungsten na karubone bingana, bifite ubukana hafi ya diyama. Carbide ya sima ifite ubukana bwinshi nubukomere bwinshi icyarimwe. Carbide ya sima ikozwe na powder metallurgie, kandi gucumura ninzira yingenzi mugihe cyo gukora ibicuruzwa bya sima. Biroroshye gutera imyenge nyuma ya tungsten karbide icumura niba itagenzuwe neza. Muri iyi ngingo, uzabona amakuru ajyanye na pore nyuma ya tungsten karbide.

Ifu ya karubide ya tungsten hamwe nifu ya binder ivangwa muburyo runaka. Hanyuma ifu ivanze ikozwe mubyatsi nyuma yo gusya mumashini yumupira, gutera akuma, no guhuzagurika. Icyatsi kibisi cyitwa tungsten carbide cyacuzwe mumatanura ya HIP.

Inzira nyamukuru yo gucumura irashobora kugabanywamo ibice bine. Nibikurwaho byububiko hamwe nicyiciro kibanziriza gucumura, icyiciro gikomeye cyo gucumura, icyiciro cyo gucumura amazi, nicyiciro cyo gukonjesha. Mugihe cyo gucumura, ubushyuhe buriyongera buhoro. Mu nganda, hari uburyo bubiri busanzwe bwo gucumura. Imwe muriyo ni hydrogène yo gucumura, aho ibice bigenzurwa na reaction reaction ya kinetics ya hydrogène hamwe nigitutu cyikirere. Naho ubundi ni gucumura vacuum, ikoresha ibidukikije cyangwa ibidukikije bigabanutse. Umuvuduko wa gazi ugenzura karbide ya sima ya sima mukugabanya umuvuduko wa reaction.

Gusa iyo abakozi bagenzuye buri cyiciro bitonze, tungsten carbide ibicuruzwa byanyuma birashobora kubona microstructure hamwe nibigize imiti. Imyenge imwe irashobora kubaho nyuma yo gucumura. Imwe mu mpamvu zingenzi ni ibijyanye n'ubushyuhe bukabije. Niba ubushyuhe buzamutse vuba, cyangwa ubushyuhe bwo hejuru bukaba buri hejuru cyane, gukura kwintete no kugenda bizaba bitaringaniye, bikavamo kubyara imyenge. Indi mpamvu ikomeye ni umukozi ukora. Binder igomba kuvaho mbere yo gucumura. Bitabaye ibyo, umukozi ukora azahindagurika mugihe ubushyuhe bwiyongera, bizavamo imyenge.

Niba ushimishijwe nibicuruzwa bya tungsten ukaba ushaka amakuru arambuye, urashobora kutwandikira ukoresheje terefone cyangwa amabaruwa ibumoso, cyangwa UKOHEREZA MAIL US hepfo yurupapuro.
