style="text-indent:25px">真空氣氛爐的主要優(yōu)點(diǎn)是：(1)減少了氣氛中有害成分(水、氧、氮)對(duì)產(chǎn)品的不佳影響。(2)對(duì)于不宜用還原性或惰性氣體作保護(hù)氣氛(如活性金屬的燒結(jié))，或容易出現(xiàn)脫碳、滲碳的材料均可用真空燒結(jié)。(3)真空可改善液相對(duì)固相的潤(rùn)濕性，有利于收縮和改善合金的組織。(4)真空燒結(jié)有助于硅、鋁、鎂、鈣等雜質(zhì)或其氧化物的排除，起到凈化材料的作用。(5)真空有利于排除吸附氣體、孔隙中的殘留氣體以及反應(yīng)氣體產(chǎn)物，對(duì)促進(jìn)燒結(jié)后期的收縮有明顯作用。如真空燒結(jié)的硬質(zhì)合金的孔隙度要明顯低于在氫氣中燒結(jié)的硬質(zhì)合金。(6)真空氣氛爐真空燒結(jié)溫度比氣體保護(hù)燒結(jié)的溫度要低一些，如燒結(jié)硬質(zhì)合金時(shí)燒結(jié)溫度可降低。這有利于降低能耗和防止晶粒長(zhǎng)大。</p><p
