摘要
研究了金属铜粉末样品分别在2.45GHz的微波烧结炉中,在碳化硅粉作为加热介质、Ar气氛的条件下,于不同温度的烧结和在常规的管式炉中氢气的保护气氛下在1050℃烧结,微波烧结的烧结周期缩短了80%。微波烧结与常规烧结的样品进行了微观形貌的对比,微波烧结在800～850℃烧结的样品可以获得均匀的显微组织。
Microwave sintering of copper powder is studied in this paper. Powder metallurgy copper samples are sintered in a 2. 45GHz microwave furnace at different temperatures with the heated medium SiC in Ar atmosphere and in a radiatively heated（conventional） furnace at 1050℃ in pure hydrogen atmosphere. The microwave sintering results in about 80% reduction of sintering period. The microstructure of microwave sintered samples is compared with that of conventional sintering of powder metallurgy copper. The samples which are microwave sintered at 800-850℃ can get homogeneous microstructures.
