Agaciro Agaciro ka Tungsten Igikoresho Cyuma Cyuma Cyuma

Gukomera nubushobozi bwibikoresho byo kurwanya ibintu bikomeye bikanda hejuru yacyo. Nibimwe mubikorwa byingenzi byerekana ibikoresho byuma.

Mubisanzwe, uko gukomera gukomeye, niko birwanya kwambara. Indanganturo zikoreshwa cyane ni Brinell gukomera, gukomera kwa Rockwell hamwe no gukomera kwa Vickers.

Gukomera kwa Brinell (HB)

Kanda umupira wicyuma ufite ubunini bunini (muri rusange mm 10 z'umurambararo) mumwanya wibikoresho hamwe nuburemere runaka (muri rusange kg 3000), hanyuma ubigumane mugihe runaka. Nyuma yo gupakurura, igipimo cyumutwaro mukarere ka indentation numubare wa Brinell (HB), naho igice ni kilo / mm2 (n / mm2).

2. Gukomera kwa Rockwell (HR)

Iyo HB> 450 cyangwa icyitegererezo ari gito cyane, gupima ubukana bwa Rockwell ntibishobora gukoreshwa aho kugerageza Brinell. Ni cone ya diyama ifite inguni yo hejuru ya dogere 120 cyangwa umupira wicyuma ufite diameter ya 1.59 na 3.18 mm. Irakanda hejuru yububiko munsi yumutwaro runaka, kandi ubukana bwibintu bibarwa uhereye mubwimbitse bwa indentation. Ukurikije ubukana butandukanye bwibizamini, birashobora kugaragazwa nubunzani butatu:

Ukurikije ubukana butandukanye bwibizamini, birashobora kugaragazwa nubunzani butatu:

HRA: Ubukomezi bwabonetse kubiro 60 kg hamwe na diamant cone indenter bikoreshwa mubikoresho bifite ubukana bwinshi (nka karbide ya sima).

HRB: Ubukomezi bwabonetse mugukomera umupira wicyuma ufite diameter ya 1.58 mm nuburemere bwa kg 100. Ikoreshwa mubikoresho bifite ubukana buke. (Nkibyuma bifatanye, ibyuma, nibindi).

HRC: Ubukomezi bwabonetse kuburemere bwa kg 150 hamwe na diamant cone indenter ikoreshwa mubikoresho bifite ubukana bwinshi (nk'icyuma kizimye).
