Chifukwa Chake Mapepala Ophimba a Chromium Carbide Amapambana Chitsulo Chovala Chachizolowezi

Kuwonongeka kwa zinthu chifukwa cha tinthu ta mchere tolimba ndi njira imodzi yowononga kwambiri m'mafakitale akuluakulu monga migodi, simenti, kupanga magetsi, ndi zitsulo. Kale zinthu zomangira mongama chute, ma hopper, matebulo opukusira, ndi zonyamulira zimawonongeka, magwiridwe antchito a zida amachepa, ndalama zokonzera zimakwera, ndipo zimazimitsidwa mosakonzekera zimachitika.

Pofuna kuchepetsa mavutowa, mbale zovekedwa ndi chromium carbide zakhala njira yodziwika bwino yamakampani, zomwe zimayamikiridwa chifukwa cha kuuma kwawo kwakukulu, mgwirizano wamphamvu wa zitsulo, komanso moyo wautali wautumiki. Komabe, kusiyana kwa magwiridwe antchito pakati pa opanga kukupitirirabe. Pepalali limapereka kuwunika kwa zitsulo ndi kuyesa kuti lifotokoze chifukwa chake WodonMa mbale ovalira a Chromium Carbide Overlay (CCO)imapereka kukana kwabwino kwambiri kwa kuvala poyerekeza ndi zitsulo zachikhalidwe zogwiritsidwa ntchito komanso mbale zolimba zogwiritsidwa ntchito pazinthu zambiri.

Kapangidwe ka Mankhwala ndi Kapangidwe ka Gawo

Kukana kwa kuvala kwa mbale yosakanikirana kumayendetsedwa makamaka ndi kapangidwe ka mankhwala omwe ali pamwamba pake ndi kapangidwe kake kakang'ono komwe kamachokera. Mapepala a Wodon amapangidwa ndi milingo yolinganizidwa bwino ya kaboni (C) ndi chromium (Cr), zomwe zimapangitsa kuti ma carbide okhala ndi chromium yambiri azitha kugwa nthawi yayitali akamauma.

Kupanga kwa Gawo la Carbide - Carbon imakumana ndi chromium kuti ipange ma carbide oyambira a Cr₇C₃ okhala ndi hexagonal, omwe amakhala ndi mphamvu zochepa mpaka HV1800, zomwe zimakhala zapamwamba kwambiri kuposa gawo lachitsulo.

Kulimba kwa Matrix - Chitsulo chofewa chachitsulo chimathandizira kulimba ndi kuyamwa mphamvu, pomwe chophimbacho chimatsimikizira kuuma kwa pamwamba. Kapangidwe kameneka ka magawo awiri kamapanga mbale yovala ya bimetallic yokhala ndi mphamvu komanso kulimba.

Machitidwe Oyesera ndi Kuyesa Mapepala Ovala a Bimetallic

Mosiyana ndi zitsulo zomangira kapena zitsulo zoyatsira moto, zomwe zimayendetsedwa ndi zofunikira zapadziko lonse lapansi (monga miyezo ya ASTM, EN, kapena GB),mbale zovekedwa ndi bimetallicpakadali pano palibe muyezo wapadziko lonse lapansi.

Pachifukwa ichi, njira yodalirika kwambiri yotsimikizira momwe zinthu zimagwirira ntchito ndi kuyesa kuphwanya gudumu la rabara la mchenga wouma. Kuyesa kokhazikika kumeneku kumabwereza kuphwanya kwa matupi atatu mwa kukanikiza gudumu la rabara pamwamba pa kuphwanya pamene akudyetsa mchenga wa silika wouma pamlingo wolamulidwa. Mwa kulemba kutayika kwa zitsanzo, kukana kuphwanya kumatha kuwerengedwa moyenera komanso mobwerezabwereza.

Mikhalidwe yoyesera:

Kugwirizana kwa Zitsanzo - Zitsanzo kuchokera ku Wodon, mbale zogulira zochokera kunja, ndi zapakhomo zinadulidwa mofanana.

Abrasive Medium - Mchenga wa quartz wozungulira unagwiritsidwa ntchito kutsanzira mikhalidwe yolusa kwambiri.

Kunyamula ndi Kutalika - Kunyamula kosasinthika kunagwiritsidwa ntchito kwa mphindi 45 pansi pa malo ofanana.

Njira imeneyi imachotsa kusiyana kwa mawonekedwe kapena magwiridwe antchito, kuonetsetsa kuti magwiridwe antchito oyezedwa amawonetsa kokha mawonekedwe a mbale iliyonse.

Zotsatira za Mayeso ndi Kusanthula Koyerekeza

Kuchepetsa thupi pambuyo pa mphindi 45:

Mbale yovala ya wodon: 0.148 g

Ma mbale otayira otumizidwa kunja: 0.229 – 0.252 g

Ma mbale ovalira m'nyumba: 0.371 – 0.399 g

Kafukufukuyu akutsimikizira kuti mbale zovekedwa ndi chromium carbide zopangidwa kudzera mu njira zapamwamba zophimba pamwamba zimaposa zitsulo zachikhalidwe m'malo owuma.
