Incamake yo gutwara ibyuma

Gutwara ibyuma bikoreshwa mugukora imipira, kuzunguruka no gutwara impeta.Gutwara ibyuma bifite ubukana buhanitse kandi bumwe, kwambara birwanya imipaka ntarengwa.Ibisabwa kugirango uburinganire bwimiti ihindurwe, ibiyikubiyemo nogukwirakwiza ibintu bitari ibyuma, no gukwirakwiza karbide zicyuma birakomeye.Nimwe murwego rukomeye rwicyuma mubikorwa byose byibyuma.

Ibyiciro by'ibyuma bisanzwe bifata ibyuma ni karubone nyinshi ya chromium ifite ibyuma bikurikirana, nka GCr15, Gcr15SiMn, nibindi. ibyuma bitwara ibyuma, nka 9Cr18, nibindi, hamwe nubushyuhe bwo hejuru bwo hejuru, nka Cr4Mo4V, Cr15Mo4V2, nibindi.

Umutungo wumubiri

Imiterere yumubiri yo gutwara ibyuma cyane cyane harimo microstructure, layer decarburized layer, non-metallic include and macrostructure.Mubisanzwe, ibicuruzwa bitangwa no gushyushya bishyushye hamwe no gushushanya bikonje.Imiterere yo gutanga igomba kugaragara mu masezerano.Makrostructure yicyuma igomba kuba idafite ubuvumo bwagabanutse, ibibyimba byo munsi yubutaka, ibibara byera na pore ya micro.Icyerekezo cyo hagati hamwe nubusanzwe muri rusange ntibishobora kurenga icyiciro cya 1.5, kandi gutandukanya ntibishobora kurenza icyiciro cya 2. Imiterere yegeranye yicyuma igomba kugabanywa kimwe pearlite nziza.Ubujyakuzimu bwa decarburisation, kutagira ibyuma hamwe no kutaringaniza karbide bigomba kubahiriza ibipimo byigihugu.
