style="text-indent:25px">介紹真空氣氛爐的高溫滲碳：鋼件的滲碳層深度要求一般都較保守，有時(shí)也很盲目。看來(lái)有必要研究決定滲碳層深度的力學(xué)因素，探討減少滲層規(guī)定的可能性。碳氮共滲。碳氮共滲溫度比滲碳低，工件畸變小。在滲層深度為0.6mm以下時(shí)的滲速接近于930℃滲碳。鋼碳氮共滲時(shí)容易出現(xiàn)反常組織，淬火后表面硬度有下降現(xiàn)象，滲層中有較多的殘留奧氏體。如何合理選擇工藝，充分發(fā)揮碳氮共滲潛力仍是值得探討的問(wèn)題。過(guò)去曾有人提倡過(guò)高濃度碳氮共滲，也曾有過(guò)鋼件碳氮共滲時(shí)表面含碳量在0.6％，具有比較好綜合力學(xué)性能的報(bào)道，為此眾說(shuō)紛紜?？磥?lái)有必要掌握這些規(guī)律，對(duì)生產(chǎn)工藝的推薦有所幫助。過(guò)去和現(xiàn)在都有對(duì)滾動(dòng)軸承施行碳氮共滲以提高接觸疲勞強(qiáng)度的報(bào)道。例如AISI52100(相當(dāng)于GCr15)鋼制的球和滾柱則由過(guò)去的淬火、回火改為碳氮共滲、淬火、回火、軸承的破壞壽命提高了2.42倍?？磥?lái)，真空氣氛爐要充分發(fā)揮碳氮共滲工藝的潛力還有許多工作需要做。真空氣氛爐加熱使用過(guò)程需使用循環(huán)水。沈陽(yáng)實(shí)驗(yàn)真空氣氛爐</p><p

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。沈陽(yáng)實(shí)驗(yàn)真空氣氛爐</p></p><br
