技術介紹
滲碳氮化(或稱氮碳共滲)是以滲氮為主同時滲入碳的化學熱處理工藝。工業生產中已廣泛應用的氮碳共滲方法有氣體法和熔鹽法。氣體氮碳共滲常用介質有50%氨+50%吸熱式氣體(Nitemper法)、35%?50%氨+50%?60%放熱式氣體(Nitroc法)和通氨時滴注乙醇等數種方法,其可在500°C?650°C溫度下共滲Ih?8h。CN1184510A號中國專利文獻公開了一種真空滲碳設備,該真空滲碳設備包括有加熱室、冷卻室、油罐、抽真空源、滲碳氣體源及惰性氣體源等,該真空滲碳設備雖然結構簡單,但是雙室結構設置缺乏合理性,且單純油槽的冷卻設備存在冷卻溫度難以控制、冷卻溫度不均衡等問題。CN202246831U號中國專利文獻公開了一種密封箱式氣體碳氮共滲爐成套設備,包括滴注式碳氮共滲多用爐、工件傳送 ...
