Cemented carbide, monga "mano amakampani", ndi chinthu chofunikira kwambiri pazida zamakono. Kugwiritsa ntchito kwake kukuchulukirachulukira, ndipo kumadziwika kwambiri m'magawo ambiri monga mafuta ndi gasi, migodi ya malasha, kuwongolera madzimadzi, makina omanga, mlengalenga ndi zina zotero. Ndiye, momwe mungagwiritsire ntchito zinthu zochepa kuti muwongolere bwino? Izi zimafuna kuwongolera magwiridwe antchito a simenti ya carbide kuti apititse patsogolo moyo wautumiki komanso magwiridwe antchito.

1.Kupititsa patsogolo ubwino wa zipangizo.

A.Sinthani chiyero cha zipangizo

Akukhulupirira kuti kufufuza zinthu monga Na, Li, B, F, Al, P, K ndi zinthu zina zotsata zomwe zili pansipa 200PPm zimakhudzidwa mosiyanasiyana pakuchepetsa, carbonization ndi sintering ya simenti carbide N ufa, Ndipo zotsatira pa katundu ndi kapangidwe ka aloyi ndi ofunika kuphunzira.Mwachitsanzo, aloyi ndi mphamvu mkulu ndi mkulu zotsatira toughness (monga migodi aloyi ndi mphero zida) ndi zofunika kwambiri, pamene mosalekeza kudula zida kazitsulo ndi katundu otsika mphamvu koma mkulu. Machining kulondola sikutanthauza mkulu zopangira chiyero.

B.Kulamulira tinthu kukula ndi kugawa zipangizo

Pewani tinthu tating'onoting'ono ta carbide kapena ufa wa cobalt, ndikuletsa mapangidwe a njere za carbide ndi maiwe a cobalt pamene aloyiyo yatenthedwa.

Pa nthawi yomweyo, tinthu kukula ndi tinthu kukula zikuchokera ya zipangizo umalamuliridwa kukumana ndi zosowa zosiyanasiyana mankhwala. Mwachitsanzo, zida zodulira ziyenera kugwiritsa ntchito tungsten carbide ufa wokhala ndi tinthu tating'onoting'ono tosachepera 2 ma microns, zida zosavala ziyenera kugwiritsa ntchito 2-3 microns tungsten carbide ufa, ndipo zida zamigodi ziyenera kugwiritsa ntchito tungsten carbide ufa wokulirapo kuposa ma microns atatu.

2. Kupititsa patsogolo microstructure ya alloy.

Ultrafine Grain Alloy

Kukula kwambewu ya carbide ndi yochepera 1μm, ndipo imatha kukhala yolimba komanso yolimba nthawi imodzi.

Zosakaniza Zosiyanasiyana Zomangamanga

Heterogeneous structure alloy ndi mitundu yapadera ya carbide yokhala ndi simenti yokhala ndi mawonekedwe osagwirizana kapena kapangidwe kake, komwe amapangidwa ndi kusakaniza mitundu iwiri ya zosakaniza ndi zigawo zosiyanasiyana kapena kukula kwa tinthu. Nthawi zambiri imakhala ndi kulimba kwa ma aloyi opangidwa ndi coarse-grained komanso kukana kwamphamvu kwa ma aloyi opangidwa bwino, kapena kulimba kwambiri kwa ma aloyi apamwamba a cobalt komanso kukana kwamphamvu kwa ma aloyi otsika a cobalt.

Superstructural Alloys

Kupyolera mu njira yapadera yopangira, mapangidwe a alloy amapangidwa ndi zigawo za anisotropic tungsten carbide single crystal flake zomwe zimagwirizanitsidwa ndi mitsempha yachitsulo ya cobalt. Alloy iyi imakhala yolimba kwambiri ndipo imakhala yolimba kwambiri ikagwidwa ndi kugwedezeka mobwerezabwereza.

Gradient Alloy

Ma alloys okhala ndi kusintha kwa gradient mu kapangidwe kake kumapangitsa kusintha kwa gradient kuuma komanso kulimba.

3. Sinthani kapena sankhani gawo latsopano lolimba komanso gawo lolumikizana.

4. Chithandizo chowumitsa pamwamba.

Konzani kusagwirizana pakati pa kukana kuvala ndi kulimba, kulimba ndi mphamvu ya simenti ya carbide.

Zokutira:Dikani wosanjikiza wa TiC kapena TiN pamwamba pa aloyi yolimba ndi kulimba bwino mwa njira zakuthupi kapena zamankhwala kuti muwonjezere kukana kwa aloyi.

Pakalipano, chitukuko chofulumira kwambiri cha boronizing, nitriding, ndi spark spark yamagetsi ndi carbide yokutidwa ndi simenti.

5. Kuwonjezera zinthu kapena mankhwala.

6. Kutentha mankhwala a simenti carbide.
