Mavuto Wamba ndi Kusanthula Chifukwa Chakupopera Kwa Hard Alloy
Hard alloy ndi alloy alloy opangidwa kuchokera kuzinthu zolimba zazitsulo zowuma ndi zitsulo zomangika kudzera muzitsulo zazitsulo, zolimba kwambiri, kukana kuvala, mphamvu zabwino komanso kulimba. Chifukwa cha ntchito yake yapadera, nthawi zambiri amagwiritsidwa ntchito popanga zida zoboola miyala, zida zamigodi, zida zoboola, zida zoyezera, ndi zina zotero. Amagwiritsidwa ntchito kwambiri m'magawo monga mafuta ndi gasi, makampani opanga mankhwala, makina opangira uinjiniya, komanso kuwongolera madzimadzi. Hard alloy ndi chinthu chopangidwa ndi kukanikiza podutsa muzitsulo za ufa.
1. Zosanjikiza
Zosanjikiza zambiri zimayambira m'mphepete ndikufikira ku billet. Chifukwa cha kusanjika kwa chipika choponderezedwa ndi kupsinjika kwamkati kwamkati kapena kulimba kwa zotanuka mu block block. Mwachitsanzo, cobalt zomwe zili mu osakaniza ndizochepa, kuuma kwa carbide ndikwambiri, ufa kapena tinthu tating'onoting'ono tating'onoting'ono, tomwe timapanga timapanga tochepa kwambiri kapena timagawidwa mosiyanasiyana, kusakaniza kumakhala konyowa kwambiri kapena kowuma kwambiri, kukanikiza kukanikiza kuli kwambiri. chachikulu, cholemera chimodzi ndi chachikulu kwambiri, mawonekedwe a chipika chopondereza ndi chovuta, kusalala kwa nkhungu kumakhala kosauka kwambiri, ndipo tebulo pamwamba pa tebulo silili lofanana, zonse zomwe zingayambitse kusanjikiza.
2. Ming'alu
Chodabwitsa cha kuthyoka kwapang'onopang'ono mu chipika choponderezedwa kumatchedwa cracking. Chifukwa cha kupsinjika kwamphamvu mkati mwa chipika choponderezana kukhala chachikulu kuposa mphamvu yamphamvu ya block block. Kupanikizika kwapakati pa compression block kumachokera ku zotanuka zamkati zamkati. Zomwe zimakhudza delamination zimakhudzanso ming'alu. Njira zotsatirazi zitha kuchitidwa kuti muchepetse ming'alu: kukulitsa nthawi yogwira kapena kukakamiza kangapo, kuchepetsa kupanikizika, kulemera kumodzi, kukonza mapangidwe a nkhungu ndikukulitsa makulidwe a nkhungu moyenera, kufulumizitsa kuthamangitsidwa, kuchulukitsa opangira, ndikuwonjezera kutayikira kwa zinthu.
