O lau ili va'a karbide e masani ona fa'aaogaina meafaigaluega tipi mo le gaosiga o oloa fafie. O le lelei o lau carbide saw e fesoʻotaʻi vavalalata ma le lelei o oloa gaosi. O le sa'o ma le talafeagai o le filifiliga o lau carbide saw e taua tele i le fa'aleleia atili o le lelei o oloa, fa'apu'upu'u ta'amilosaga fa'agaioiga, ma fa'aitiitia le tau o le gaosiga.
1. Filifiliga o mata ili carbide
O lau va'ai Carbide e aofia ai le tele o fa'ailoga e pei o le ituaiga ulu tipi, mea o le matrix, lautele, numera o nifo, mafiafia, foliga nifo, tulimanu, avanoa, ma isi. . Pe a filifilia se mata ili, e tatau ona e filifilia le saʻo saʻo lau e tusa ai ma le ituaiga, mafiafia, saosaoa vaʻavaʻa, vaʻa faʻatonuga, fafaga fafaga, ma le vaʻa vaʻaia o le mea o loʻo tipiina.
(1) Filifiliga o ituaiga carbide sima
E masani ona faʻaaogaina ituaiga o carbide sima o le tungsten-cobalt (code YG) ma le tungsten-titanium (code YT). Talu ai ona o le tungsten-cobalt carbide e sili atu ona lelei aʻafiaga, e sili atu ona faʻaaogaina i le gaosiga o fafie. O faʻataʻitaʻiga masani e faʻaaogaina i le gaosiga o fafie o YG8-YG15. Ole numera ile YG o lo'o fa'aalia ai le pasene o mea ole cobalt. A'o fa'atupula'ia le anotusi o le cobalt, e fa'atupula'ia le malosi o le a'afiaga ma le malosi o le pa'u, ae fa'aitiitia le maa'a'a ma le ofuina. E tatau ona Filifili e tusa ai ma le tulaga moni.
(2) Filifiliga o matrix
1. 65Mn spring steel has good elasticity and plasticity, economical material, good heat treatment hardenability, low heating temperature and easy deformation, so it can be used for saw blades with low cutting requirements.
2. Uamea meafaigaluega kaponi e maua ai le maualuga o le carbon ma le maualuga o le vevela, ae o lona maaa ma le ofuina o le teteʻe e pa'ū malosi pe a faʻaalia i le vevela o le 200°C-250°C. E tele le vevela togafitiga deformation, le lelei hardenability, ma e faigofie ona ta'e pe a uma le taimi umi tempering. Fai mea tau tamaoaiga mo meafaigaluega tipi e pei o T8A, T10A, T12A, ma isi.
3. Fa'atusatusa i le uamea meafaigaluega carbon, uamea meafaigaluega uamea e lelei le fa'afefeteina o le vevela, ofuina le fa'aogaina ma sili atu le fa'atinoina o galuega. O le vevela vevela faʻafefeteina o le 300 ℃ - 400 ℃, lea e talafeagai mo le gaosiga o mata ili liʻo maualuga.
4. Uamea meafaigaluega maualuga-saosaoa lelei hardenability, malosi malosi ma rigidity, ma itiiti vevela-tetee deformation. O se u'amea sili-maualuga-malosi ma mautu thermoplasticity ma e talafeagai mo le gaosiga ultra-maniifi ili mata ma uiga lelei.
