Iko kusakara kwekupfeka kwesimbi yakavezwa kunokonzerwa neakakwira kabhoni yezviri pamusoro pechiso. Kana iyo kabhoni simbi w (C) iri pasi pe0.43%, iyo carburized chikamu ine mukana mune kusakara kuramba, uye kana w (C) Kana iri pamusoro kupfuura 0.45%, iko kusanzwira kuramba kweiyo induction yakaoma zvikamu kunovandudzwa. Iyi ndiyo mhedziso yekuti TH HACAHOBA yatora zvichibva pabvunzo yemunda wepini pini. Naizvozvo, iyo pani yetarakita pini inotsiviwa neiyo nyowani yekumisikidza yekuomesa maitiro esimbi makumi mashanu. . Iko kuenzanisa kwekupfeka kwekushomeka kweakasiyana w (C) simbi mushure mekudzikiswa kwekudzima kunoratidzira kukanganisa kwesimbi yekuumbwa. Iyo data iri mutafura inoratidza kuti T50 simbi ine hushoma huwandu hwekupfeka, uye yayo kabhoni zvemukati uye kuomarara zvakare zvakakwirira; 7 simbi uye 45Mn vane yakafanana kusakara kuramba; 50Cr simbi ine kusakara kuramba pakati peT45 simbi uye 7Mn simbi, zvichiratidza kuti iyo simbi iri Mukati Ming inogona kugadzirisa abrasion kuramba.
