Aotelega o le U'amea Uamea

O lo'o fa'aaogaina le u'amea e fai ai polo, ta'avale ma mama amo. Tuuina atu uamea e maualuga ma tutusa maaa, ofuina tete'e ma maualuga tapulaa elastic. O manaʻoga mo le tuʻufaʻatasia o vailaʻau vailaʻau, o mea e aofia ai ma le tufatufaina atu o mea e le o ni uʻamea, ma le tufatufaina atu o carbide o le faʻapipiʻiina o le sila e matua faʻamaoni. O se tasi lea o fa'ailoga uamea sili ona mamafa i le gaosiga o u'amea uma.

O togi uʻamea o uʻamea masani masani o le maualuga o le carbon chromium o loʻo faʻapipiʻiina le uʻamea, e pei o le GCr15, Gcr15SiMn, ma isi. Cr4Mo4V, Cr15Mo4V2, ma isi.

Meatotino faaletino

O meatotino faʻaletino o le faʻapipiʻiina o uamea e masani lava ona aofia ai le microstructure, decarburized layer, non-metallic inclusion and macrostructure. E masani lava, o oloa o loʻo tuʻuina atu e ala i le vevela taʻavale annealing ma le malulu ata tusi annealing. O le tulaga o le tu'uina atu e tatau ona fa'aalia i totonu o le konekarate. Ole fa'ameamea ole sila e tatau ona sa'oloto mai le fa'aitiitiga o le pu, fa'apogai i lalo o le pa'u, pa'epa'e ma micro pore. O le porosity tutotonu ma le porosity lautele e le tatau ona sili atu i le vasega 1.5, ma o le vavaeeseina e le tatau ona sili atu i le vasega 2. O le fausaga faʻapipiʻi o le uamea e tatau ona faʻasoa faʻatasia le pearlite fine-grained. O le loloto o le decarburization layer, non-metallic inclusions ma carbide unegness e tatau ona tausisia tulaga talafeagai a le atunuu.
