style="text-indent:25px">氣氛爐中的真空氣氛爐是一種采用物體在通入一定氣體的爐膛內(nèi)進(jìn)行燒結(jié)的方法的氣氛爐產(chǎn)品，在真空燒結(jié)時(shí)，常發(fā)生金屬的揮發(fā)損失，對(duì)于含碳材料的脫碳可以用增**末料中的含碳量以及控制真空度來(lái)解決。下面給大家說(shuō)說(shuō)真空氣氛爐的優(yōu)勢(shì)特點(diǎn)：1、對(duì)于氣氛爐工作過(guò)程中不宜用還原性或惰性氣體作保護(hù)氣氛的燒結(jié)。2、真空氣氛爐能夠利于收縮和改善合金的組織，優(yōu)化相對(duì)固相的潤(rùn)濕性。3、氣氛爐真空環(huán)境燒結(jié)過(guò)程減少了氣氛(水、氧、氮)中有害成分對(duì)產(chǎn)品的不良影響。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、真空氣氛爐內(nèi)的真空環(huán)境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，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、真空氣氛爐的真空環(huán)境的燒結(jié)溫度比氣體保護(hù)燒結(jié)的溫度要低一些，所以在燒結(jié)硬質(zhì)合金時(shí)燒結(jié)溫度可降低100～150℃。這有利于降低能耗和防止晶粒長(zhǎng)大。廣東實(shí)驗(yàn)真空氣氛爐</p></p><br
