Mushure mechubhu yemativi manaKana yapiswa, ganda reganda re oxide nhema rinoonekwa, izvo zvinokanganisa chitarisiko. Tevere, tichatsanangura zvakadzama maitiro ekubvisa ganda re oxide pachubhu ine dhayamita hombe.
Zvinonyungudutsa uye emulsion zvinoshandiswa kuchenesa pamusoro pemvurapombi yemativi mana ine dhayamita hombekubvisa mafuta, mafuta, guruva, mafuta ekubikisa nezvimwe zvinhu zvakafanana zve organic. Zvisinei, haikwanise kubvisa ngura, oxide scale uye flux pamusoro pepombi ine dhayamita hombe, saka inoshandiswa chete senzira yekubatsira mukudzivirira ngura.
Kazhinji, nzira dzemakemikari nemagetsi dzinoshandiswa pakurapa kusvina. Kusvina kwemakemikari chete ndiko kunoshandiswa pakurwisa ngura yemapaipi, izvo zvinogona kubvisa oxide scale, ngura uye coating yekare. Dzimwe nguva, inogona kushandiswa sekugadzirisazve mushure mekuputirwa nejecha. Kunyangwe kuchenesa kwemakemikari kuchigona kuita kuti pamusoro payo pave nekuchena uye kuomarara, maitiro ayo ekudzivirira haana kudzika uye ari nyore kukonzera kusvibiswa kune nharaunda yakapoteredza. Mapaipi emativi mana akakura anofanira kuiswa kuti agamuchirwe muzvikamu, uye mitemo yezvikamu inofanira kutevedzera zvinodiwa nezvinodiwa nezvinodiwa nezvigadzirwa.
Zvinhu zvekuongorora, huwandu hwesampuli, nzvimbo dzekutora sampuli uye nzira dzekuyedza dzemapaipi akakura-dhayamita akaenzana zvinofanira kuenderana nezvinodiwa nezvinodiwa zvechigadzirwa. Nemvumo yeanoda, hot-rolledmachubhu akaenzana nedhayamita hombeinogona kutorwa muzvikamu zvichienderana nemapoka emidzi yakakungurutswa.
Kana mhedzisiro yebvunzo dzemachubhu makuru-dhayamita akasasangana nezvinodiwa nezvinodiwa nezvinodiwa zvechigadzirwa, asina kukodzera anofanira kusarudzwa, uye huwandu hwakapetwa kaviri hwemasampuli hunofanira kutorwa kubva muboka rimwe chete remachubhu makuru-dhayamita kuti aongororwezve zvinhu zvisina kukodzera. Kana mhedzisiro yekuongorora zvakare (kusanganisira chero indekisi inodiwa nebvunzo yepurojekiti) isina kukodzera, boka remachubhu makuru-dhayamita haafanire kuendeswa. Kana zvinhu zvinotevera zvekuongorora zvikasabudirira pakuongorora kwekutanga, kuongororwa zvakare hakubvumirwi: a Kune mavara machena mumatishu e macroploid; b. Microstructure.
