Mapangidwe a Metallographic a enamel pazitsulo zotayidwa

Chophikira chachitsulo chopangidwa ndi enamel chimapangidwa kuchokera kumagulu enaake achitsulo, kuphatikiza ferrite ndi pearlite. Ferrite ndi gawo lofewa komanso lokhazikika, pomwe pearlite imaphatikiza ferrite ndi simenti, kuwapatsa mphamvu ndi kuuma.

Mukamagwiritsa ntchito zokutira za enamel poponya chitsulo, ndikofunikira kumvetsetsa kapangidwe ka metallographic kuti zitsimikizire kuti zimamatira bwino komanso kulimba. Tsamba ili labulogu lisanthula kapangidwe kachitsulo kachitsulo, makamaka makamaka pazigawo zomwe zimathandizira kugwiritsa ntchito bwino zokutira enamel.

1. Base Layer: Gray Cast Iron
Chitsulo chachitsulo chomwe chimagwiritsidwa ntchito popaka enamel nthawi zambiri chimakhala chitsulo chotuwa. Chitsulo chamtundu woterechi chimadziwika ndi kuchuluka kwa carbon, chomwe chimapatsa mphamvu kwambiri komanso kukana kuvala. Amadziwikanso ndi ma graphite flakes, omwe amapereka matenthedwe abwino komanso amachepetsa brittleness.
2. Kukonzekera kwa gawo lapansi: Kuwombera mchenga ndi kuyeretsa
Pamwamba pazitsulo ziyenera kukonzedwa kuti zithandizire kumamatira koyenera kwa zokutira za enamel. Izi nthawi zambiri zimaphatikizapo kupukuta mchenga kuti muchotse zonyansa zilizonse, ndikutsatiridwa ndi kuyeretsa bwino kuti pakhale malo oyera, osalala kuti enamel amamatire.
Kwa zokutira za enamel, chitsulo choponyedwa chiyenera kukhala ndi chiŵerengero choyenera cha ferrite ndi pearlite. Zolemba izi zimapereka maziko olimba kuti enamel azitsatira ndikuonetsetsa kuti zokutirazo zikhale zolimba. Gawo la ferrite limathandizira kuyamwa ndi kugawa kutentha mofanana, pamene gawo la pearlite limawonjezera mphamvu ndi kukana kuvala.

Kuphatikiza pa ferrite ndi pearlite, zinthu zina monga kaboni, silicon, ndi manganese zimagwira ntchito yofunika kwambiri. Mpweya wa kaboni uyenera kukhala wocheperako kuti ukhale wolimba komanso kuti usawonongeke. Silicon imathandizira kumamatira kwa zokutira za enamel, pomwe manganese amawonjezera mphamvu zonse komanso kulimba kwachitsulo chonyezimira.
Mwachidule, kapangidwe koyenera ka zophikira zachitsulo zokutidwa ndi enamel zimaphatikizanso chiŵerengero choyenera cha ferrite ndi pearlite, mpweya wochepa wa carbon, ndi kukhalapo kwa silicon ndi manganese. Izi zimatsimikizira zokutira zokhazikika za enamel, ngakhale kugawa kutentha, komanso kugwira ntchito kwanthawi yayitali kwa chophikacho

Kuyeretsa mphika wogwiritsidwa ntchito wachitsulo cha enamel kumatha kuchitika bwino ndi izi:
