Tungsten Carbide
Fa'amatalaga
Tungsten carbide o se tioata hexagonal uliuli ma luster metallic, ma lona maaa e tutusa ma taimane. Ose ta'avale lelei o le eletise ma le vevela. Ua faʻaaogaina lautele i le gaosiga o meafaigaluega tipi saosaoa, mea faʻapipiʻi kiln, vaega afi afi, cermets ma elemene faʻavevela tetee, etc.Pure tungsten carbide e vaivai ma e mafai ona faʻaitiitia ai le pala pe afai o se vaega itiiti o metala e pei o le titanium ma cobalt e. faʻaopoopo. I le avea ai o se mea faigaluega sili ona faigata ma ofuina mea faʻafefete, e mafai ona fausia ai se vaifofo mautu ma le tele o carbide.WC-TiC -Co faʻapipiʻiina meafaigaluega carbide ua faʻaaogaina lautele.E mafai foi ona faʻaaogaina e avea o se faʻaopoopoga faʻaleleia mo NbC-C ma TaC-C ternary system carbide, lea e le gata e faʻaitiitia ai le vevela o le sintering, ae faʻatumauina foi le lelei o le faatinoga ma e mafai ona faʻaaogaina o se mea avanoa.
Fa'aaogāga
u'amea malo, elemene fa'avevela tetee, cermet etc
