Chifukwa chiyani mbale yathu yovala zovala ili ndi kukana kwabwino chonchi?

1. Kuchulukana kwa mankhwala ndi chinsinsi.

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

Chigawo chamankhwala ichi chimabweretsa kuchuluka kwa Cr7C3 chrome carbide hard particles. The micro-hardness (mpaka HV1800)mwa iziparticles mu wosanjikiza adzatsimikizira wapamwamba kuvala kugonjetsedwa pamwamba.

 

 

 

 

 

 

 

 

 

 

Kuyesa Kachitidwe:

Zida zoyesera: Gudumu la mphira mchenga wa Quartzmakina oyesera abrasion.

Zoyenera: 1. Kusankha zitsanzo za miyeso yofananira ya zida zosiyanasiyana ndikupangira ma mbale, ndikuyikapansi pamikhalidwe yofanana yogwirira ntchito mu zida zathu zoyesera.

2. Chromium carbide microstructure

Kukana kuvala kwa mbale yovala kumadalira makamaka kuuma, mawonekedwe, kukula, kuchuluka ndi kugawa kwa chromium.carbide zolimba particles.

 

Monga momwe mungawonere pa chithunzichi, gawo la carbide (Cr7C3) pa microstructure lili pamwamba pa 50%.

 

3. Mphamvu yolumikizana pakati pa zokutira ndi mbale yoyambira.

Chipinda chogona komanso choyambira chimalumikizana bwino kwambiri. Chophimbacho chidzalowa mu mbale yoyambira pafupifupi 0.8mm-1.8mm, kufikampaka 350Mpa pamayeso athu.
