Kuwunika kwa Njira Zopangira Zopangira Zolimba Zolimba

Tonse tikudziwa kuti chigawo chachikulu cha aloyi olimba ndi yaying'ono kakulidwe carbide ufa wa kuuma mkulu ndi zitsulo refractory. Choncho, ndi olimba kwambiri, ndipo anthu ambiri akufunsa ngati aloyi zolimba ntchito aloyi aloyi mpira mano ndi chitsulo? Kodi alloy yolimba idayamba bwanji? Pansipa, wopanga mizere yolimba akufotokozerani njira yopangira zida zolimba za alloy mpira.

1. Njira yopangira zitsulo zazitali zolimba ndi motere: choyamba, alloy yomangirira imapangidwa ndi kugaya kwamphamvu kwa mpira; Kenako, molingana ndi chiŵerengero cholemera cha zigawo zolimba za aloyi, kusakaniza kumawonjezeredwa ndi kugonjetsedwa ndi kulimbikitsa mphero. Chisakanizo cha aloyi cholimba chomwe chimapangidwa ndi mphero ya mpira ndiye kuti chopimidwacho chimapangidwa.

2. Mano olimba omwe amagwiritsidwa ntchito popanga mano a mpira wautali wolimba kwambiri amaphatikizapo tungsten carbide (WC) ndi titanium carbide (TC). Ma aloyi olimba makamaka amaphatikizapo tungsten cobalt based (WC+Co) hard alloys (YG), tungsten titanium cobalt based (WC+TiC+Co) hard alloys (YT), tungsten tantalum cobalt based (WC+TaC+Co) hard alloys (YA), tungsten titanium tantalum cobalt based (WC+Cobalt) aTalloys (WC+CoYC)

3. Mtundu wa ultra-fine hard alloy ball tooth hard alloy ndi njira yake yopangira. Aloyi ndi aloyi gulu wopangidwa ndi zigawo zikuluzikulu zitatu: WC molimba gawo, Co Al monga chomangira zitsulo gawo, ndi osowa lapansi zitsulo gawo gawo; The zikuchokera ndi kulemera zili aloyi ndi motere: Co Al bonding zitsulo gawo: Al13-20%, Co80-87%; aloyi gulu: Co-AL 10-15%, Re1 ~ 3%, WC82 ~ 89%. Njira kupanga ndi motere: choyamba, chomangira aloyi Co Al ndi nthaka kuchokera ku mipira yamphamvu kwambiri; Ndiye, malinga ndi zotchulidwa kulemera chiŵerengero cha zolimba aloyi zigawo zikuluzikulu, osakaniza ndi osakaniza ndi pansi kulimbitsa mpira mphero. Kusakaniza kolimba kwa alloy komwe kumapangidwa ndi mphero ya mpira ndiye kuti vacuum sintered pa kutentha kwa sintering 1360 ℃ ndi nthawi yogwira kwa mphindi 20. Aloyi yolimba kwambiri imapangidwa.
