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 maualuga ma le maualuga o mea mataʻutia, ma maua mai le WCu mea faʻapipiʻi eletise ma mea faʻafefe vevela ma le lelei tele o le faʻatinoga pe a uma ona oomiina, sintering maualuga-vevela ma infiltration.
Tulaga lelei o le Tungsten Copper (WCu) Mea Fa'apipi'i Fa'aeletonika
1. O le tungsten copper mea faʻapipiʻi faʻaeletoroni o loʻo i ai se faʻalauteleina o le 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'atosina sintering e fa'aopoopoina e fa'atumauina lelei le fa'avevela vevela;
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.

Faʻaaogaina o Tungsten Copper Heat Sinks
Mea e talafeagai mo le afifiina ma masini maualuga, e pei o substrates, eletise maualalo, ma isi; fa'avaa ta'ita'i maualuga; laupapa pulea vevela ma radiators mo masini fa'aaluma a le militeri ma tagata lautele.
