Kuwunika Kwambiri kwa Cemented Carbide


Pofufuza ndi kupanga zinthu zopangidwa ndi simenti ya carbide, nthawi zambiri timaona "kusunga zinthu zina za carbide yomangidwa ndi simenti ndikuwongolera kulimba kwake momwe tingathere" ngati cholinga cha kafukufuku, kuti tipeze ntchito yabwino.

Monga zida zachitsulo, kulimba kwa simenti ya carbide kumatha kuwonetsedwa potengera kulimba kwamphamvu komanso kulimba kwapang'onopang'ono. Pali mgwirizano wa mzere pakati pa kulimba kwamphamvu ndi kusinthasintha kwamphamvu kwa simenti ya carbide. Zomwe zimatsimikizira mphamvu ya flexural ya alloy zimakhudzanso kwambiri kulimba kwa alloy. Mphamvu yamphamvu ya alloy imakhudzidwanso ndi zinthu zina.

Kulimba kwamphamvu ndikuthekera kwa chinthu kukana kulephera pakukweza. Zowonongeka zamkati mu aloyi zimakhala ndi zotsatira zofanana pa mphamvu yosinthasintha komanso kulimba kwamphamvu. Nthawi zambiri, ma aloyi olimba ndi zida zowonongeka, ndipo zotanuka zosinthika ntchito zimakhala ndi gawo lalikulu zikakhudzidwa, kotero mphamvu yosunthika ya aloyi imakhala ndi chikoka chofunikira pakukula kwamphamvu.

Kwa aloyi yomwe ili ndi 10% Co, ndikuwonjezeka kwa WC kukula kwambewu, ngakhale kulimba kwa aloyi kumawonjezeka, mphamvu yosunthika imachepa komanso kulimba kwamphamvu kumachepanso, zomwe zikuwonetsa kuti mphamvu yosinthika imathandizira kulimba kwamphamvu. .

Pamene kuuma kwa simenti ya carbide kumawonjezeka, kulimba kwa fracture kumachepa. Koma mkati mwamtundu wina, zikuwonetsa kuti zinthu zina zimakhudzanso kulimba kwa fracture pansi pa kuuma komweko.

Pofufuza mgwirizano pakati pa kulimba kwamphamvu, kulimba kwa fracture ndi zinthu zina zamakina ndi magawo amapangidwe a carbide yopangidwa ndi nyimbo zosiyanasiyana, kukula kwa tinthu tating'ono ta WC ndi zochitika zosiyanasiyana, timapeza mfundo zotsatirazi:

Pali zinthu zambiri zomwe zimakhudza kulimba kwa mtengo wa simenti wa carbide, makamaka kuphatikiza zolakwika zamapangidwe, mphamvu ndi kulimba, ndi zina. Mphamvu ya flexural ya alloy imakhala ndi chikoka chachikulu pazovuta zamphamvu. Pokhapokha ngati ali ndi mphamvu yofananira, ma alloys okhala ndi kulimba kwapang'onopang'ono amawonetsa kulimba kwabwinoko.

Kulimba kwa fracture kwa simenti ya carbide kumakhudzana makamaka ndi kuuma. Pamene kuuma kwa alloy kumawonjezeka, kulimba kwa fracture kumachepa kwambiri, koma kumasinthasintha mkati mwamtundu wina. Kulimba kukakhala kofanana, aloyi ya Coarse-grained low-Co imakhala ndi kulimba kwabwinoko. Ma aloyi opangidwa ndi ma homogeneous ali ndi kulimba kwapang'onopang'ono koma kutsika kwamphamvu kosunthika komanso kulimba kwamphamvu kuposa ma aloyi osapangidwa mosiyanasiyana.

Poyerekeza ndi kulimba kwamphamvu kwa simenti ya carbide, kulimba kwa fracture kuli ndi tanthauzo lofunikira kwambiri. Kuphatikizidwa ndi zizindikiro zitatu zamakina zogwirira ntchito za kulimba kwa fracture, kuuma ndi kusinthasintha kwa mphamvu ya alloy, Ikhoza kuwonetsa bwino ntchito ya alloy.
