Chifukwa chiyani mbale yathu imakhala ndi kukana kwabwino?

1. Makina ophatikizika ndiwo fungulo.

Zosakaniza zazikulu za mbale za Wodon ndi C (%): 3.0-5.0 ndi Cr (%): 25-40.

Gawo la mankhwalawa limabweretsa kuchuluka kwakukulu kwa ma Cr7C3 chrome carbide olimba. The yaying'ono-kuuma (mpaka HV1800) mwa awa tinthu tating'onoting'onoting'onoting'onoting'onoting'onoting'onoting'ono kamene kamakhala kotsimikizika kumatsimikizira kuti ndizovala zabwino kwambiri.

 

 

 

 

 

 

 

 

 

 

Magwiridwe Mayeso:

Zida Zoyesera: Gudumu la mchenga wa Quartz kumva kuwawa makina

Zoyenera kuchita: 1. Kusankha mitundu yoyimira yazinthu zosiyanasiyana ndi kuvala opanga mbale, ndikuyika pansi pofananira ndi magwiridwe antchito pazida zathu zoyesera.

2. Chromium carbide microstructure

Kutha kwa mbale yosalala kumadalira makamaka kuuma, mawonekedwe, kukula, kuchuluka ndi kufalitsa kwa chromium carbide tinthu tolimba.

 

Monga mutha kuwonera pachithunzichi, carbide (Cr7C3) kachigawo kakang'ono ka microstructure kali pamwamba pa 50%.

 

3. Kulimbitsa mphamvu pakati pa pamwamba pake ndi mbale yoyambira.

Kukutira ndi mbale yoyambira ndiyabwino kwambiri. Kukutira kumalowera m'mbale yoyambira pafupifupi 0.8mm-1.8mm, kufikira mpaka 350Mpa pamayeso athu.
