1. Iimpawu eziphambili: Isiseko sokuGqwesa
I-Tungsten Copper kunye ne-Molybdenum Copper alloys yi-powder metallurgy composite. Ayiyomixube ilula kodwa yenziwa ngeenkqubo ezintsonkothileyo ezifana nokungeniswa kwe-sintering, apho i-tungsten ene-porous okanye i-molybdenum skeleton izaliswe ngobhedu olunyibilikisiweyo. Oku kuphumela kwiseti eyodwa yeepropati ezilungelelanisiweyo:
- I-Controllable Thermal Expansion: I-Thermal Expansion Coefficient (CTE) inokuqulunqwa ngokuchanekileyo ngokulungelelanisa umlinganiselo wesinyithi. Umzekelo, icwecwe lobhedu le-Tungsten eline-85% W-15% Cu inokufikelela kwi-CTE ephantsi njenge-6.5 ppm/ idigri, ivumela ukusondelelana ngokugqibeleleyo neeseramiki ezifana ne-Alumina okanye imathiriyeli ye-semiconductor efana ne-GaAs. Oku kunciphisa uxinzelelo lwe-thermal kwaye kuthintele ukungaphumeleli kwi-interfaces ebalulekileyo.
- I-High Thermal Conductivity: Isigaba sobhedu esiqhubekayo ngaphakathi kwi-composite sibonelela ngendlela ebalaseleyo yokudlulisa ubushushu. Amaxabiso aqhelekileyo e-thermal conductivity aqala kwi-160 ukuya kwi-240 W/(m·K), eyenza ubushushu obukhawulezayo bunwenwe busuka kwiindawo ezishushu.
- Amandla oMatshini aKhethekileyo: Nokuba nomxholo ophezulu wobhedu, i-skeleton yentsimbi ephikisayo inika amandla amangalisayo kunye nobungqongqo kumaqondo obushushu aphakamileyo, ukodlula ubhedu olusulungekileyo. Oku kuqinisekisa uzinzo lwe-dimensional under thermal cycling.
- Itshathi ilandelayo ithelekisa iipropati eziphambili zezi zinto zixutywe nobhedu olusulungekileyo, ziqaqambisa ukuguquguquka kwazo okuphezulu:
2. AmaBanga oMathiriyeli kunye neeFomu: Ukuhlangabezana neeMfuno eziDityanisiweyo zeSicelo
