Gusenya. Kuraho inshinge zifunze zometse muri sisitemu yo gutanga lisansi ya moteri ya mazutu, hanyuma usibangane urushinge rwa inshinge numubiri wa inshinge. Kubera ko inshinge zagurishijwe nisosiyete zafunzwe mubice, inshinge 20 zifunze zatoranijwe kubushake kugirango zisenywe.
Guhitamo. Koresha umuyonga kugirango ukusanyirize umwanda wicyuma kuri 20 zatewe no gutera inshinge 20.
Clean. Shira icyuma gihumanya icyuma cyegeranijwe kuri nozzle no gutera inshinge umubiri winjizamo ikirahure gisukuye, ongeramo "umuti wa acetone", winjize icyuma cyanduye, hanyuma usukure hamwe na "ultrasonic cleaner" muminota 15 kugirango ukureho Impurities . Nyuma yo gukuraho umwanda wanduye, shyira kumpapuro zungurura kugirango wumuke.
Osa Mosaic. Fungura imashini ya "metallographic mosaic mashine", shyira icyuma gisukuye kandi cyumye cyometse mubibumbano, ubipfundikire "ibikoresho bya mozayike ya metallografiya", hanyuma ufunge ifu hanyuma ubikande cyane, hanyuma ufungure "imashini ya mosaic metallographic". Shyiramo amashanyarazi ya mashini, shyira ubushyuhe (140 ± 10) ℃, uzimye amashanyarazi nyuma yo kugera ku bushyuhe hanyuma ukomeze gushyuha muminota 20, hanyuma ukonje bisanzwe muminota 20, fungura ifu, hanyuma usohoke icyitegererezo cyometseho umwanda.
Preparation Gutegura icyitegererezo. Kuri "imashini yerekana ibyuma byerekana ibyuma", "ubwoya" cyangwa "veleti" ikoreshwa nkigitambaro cyo gusya kugirango isukure icyitegererezo cyasizwe na "sandallaper sandpaper". Ongeramo "metallographic polishing agent" kugeza igihe cyo gusya cyahagaritswe numwanda wicyuma kigera hejuru yindorerwamo yoroshye nta gushushanya.
