Ultra-fine copper coated molybdenum powder or ultrafine tungsten powder The present invention relates to a ultra-fine copper coated molybdenum powder or ultrafine tungsten powder, pre-coated molybdenum powder or ultra fine tungsten powder average particle size D50 of not more than 1.3μm, the average thickness of copper coating not more than 300nm, the surface of copper clad rate of not less than 50%;The actual needs of the tungsten can be copper, molybdenum-copper ratio, mixed with the copper machinery, isostatic pressing, sintering the copper-coated ultrafine tungsten powder, molybdenum powder superfine copper surface could be infiltrating theCompact structure can be prepared, homogeneous molybdenum copper, tungsten copper materials, to meet the heat sink material, electric vacuum material requirements.
Nagpakita ang pag-aaral Ang na ang pagdaragdag ng maliit na halaga ng lanthanum oksaid na lubhang pinabuting ang mekanikal mga katangian ng materyal ng molibdenum, lanthanum, molibdenum init paggamot pagkatapos ng likido nitrogen sa kuwarto temperatura zone na mayroon mahusay na lakas at kayamutan . Gayunpaman, pagproseso ng plastic pagpapapangit at init ay hindi sapat na pinag-aralan ang pag-uugali ng lanthanum oksaid .
