Tungsten Copper WCu Fa'a'avevela
Fa'amatalaga
Tungsten 'apamemea mea fa'apipi'i fa'aeletoroni o lo'o i ai uma le fa'alauteleina o meatotino o le tungsten ma le maualuga o le vevela o le conductivity o le 'apamemea.O le mea e sili ona taua o lona faʻalauteleina o le vevela ma le faʻaogaina o le vevela e mafai ona mamanuina e ala i le fetuunaʻi o le tuufaatasiga o mea e maua ai le faigofie tele.
O loʻo faʻaaogaina e le FOTMA le mama ma le maualuga o mea mataʻutia, ma maua mai le WCu mea faʻapipiʻi eletise ma mea e faʻafefe ai le vevela ma le lelei tele o le faʻatinoga pe a uma le oomiina, faʻafefe maualuga le vevela ma le faʻaogaina.
Tulaga lelei o Tungsten Copper (WCu) Mea Faʻapipiʻi Faʻaeletonika
1. O le tungsten copper mea faʻapipiʻi faʻaeletoroni o loʻo i ai se fetuutuunaiga faʻalauteleina o le vevela, lea e mafai ona faʻafetaui ma mea eseese (e pei o: uʻamea uʻamea, uʻamea valve, silicon, gallium arsenide, gallium nitride, alumini oxide, ma isi);
2. E leai ni elemene fa'aosoina sintering e fa'aopoopoina e fa'atumauina lelei le fa'avevelaina lelei;
3. Maualalo porosity ma lelei ea tightness;
4. Pulea lelei tele, fa'ai'uga luga ma mafolafola.
5. Tuuina atu pepa, vaega faia, e mafai foi ona ausia manaoga o le electroplating.
