1. Agyapade Titiriw: Fapem a Ɛfa Nneɛma a Ɛyɛ Paara Ho
Tungsten Kɔbere ne Molybdenum Kɔbere a wɔde afra yɛ powder metallurgy afrafra. Ɛnyɛ nneɛma a wɔde afrafra a ɛnyɛ den na mmom wɔde akwan a ɛyɛ nwonwa te sɛ infiltration sintering, baabi a wɔde kɔbere a wɔabɔ no ahyɛ tungsten anaa molybdenum nnompe a ɛwɔ abon mu ma so na ɛyɛ. Eyi de agyapade soronko bi a wotumi sesa mu ba:
- Controllable Thermal Expansion: Wobetumi ayɛ Thermal Expansion Coefficient (CTE) no pɛpɛɛpɛ denam nsakrae a wɔbɛyɛ wɔ dade nsusuwii mu no so. Sɛ nhwɛso no, Tungsten kɔbere krataa a ɛwɔ 85%W-15%Cu betumi anya CTE a ɛba fam te sɛ 6.5 ppm/℃, a ɛma kwan ma ɛne ceramics te sɛ Alumina anaa semiconductor nneɛma te sɛ GaAs hyia pɛpɛɛpɛ. Eyi ma ɔhyew mu nhyɛso so tew na esiw huammɔdi ano wɔ critical bonded interfaces mu.
