"Comparative sample" metallographic tsarin: metallographic tsarin na karfe ƙazantar block ne ferrite.

Tsarin metallographic na "samfurin kwatance" shine kamar haka:

A.The metallographic tsarin na famfo jiki na high-matsi famfo neα m bayani + acicular eutectic silicon;

B. The metallographic tsarin na plunger, ta metallographic tsarin shi ne martensite + granular carbide;

C. The metallographic tsarin na plunger hannun riga, da surface metallographic tsarin ne martensite + riƙe austenite;

D. Tsarin metallographic na harsashi mai injector, wanda shine pearlite mai banƙyama + babba da ferrite na reticular.

E. Allura bawul metallographic tsarin, ta metallographic tsarin ne martensite + band

F. Tsarin metallographic na jikin bawul ɗin allura, tsarinsa na ƙarfe shine martensite + granular carbide;

G. Tsarin ƙarfe na babban bututun matsa lamba shine ferrite.

Ta hanyar kwatancen da ke sama, tsarin metallographic na bututun mai mai matsananciyar matsin lamba ya yi daidai da na toshewar ƙazanta na ƙarfe, duka biyun ferrite ne, wanda ke nuna cewa toshewar an cire shi daga bututun mai mai ƙarfi, sannan ya ƙayyade tushen da karfe blockage. A karshe, an ba da shawarar cewa, a lokacin da ake daidaita tsarin samar da man dizal, ya kamata a karfafa tarwatsawa da tsaftace bututun mai da ake amfani da su, kuma an samu sakamako mai kyau.

Tare da ci gaba da ci gaban tattalin arzikin kasuwa da haɓaka gasa na kasuwa, samfurin da ke da ƙarfi mai ƙarfi dole ne ya kasance yana da kyawawan alamun aiki ban da abubuwan farashi, kuma mafi mahimmanci, dole ne ya sami ingantattun alamun aminci da ƙarancin gazawar da ake amfani da su. Don haka, haɓaka amincin samfuran shine buƙatar gasar kasuwa kuma ɗayan abubuwan da ake buƙata don samfuran su kasance masu gasa.
