單一工位的氣冷淬火爐是在加熱保溫完成后在加熱室內(nèi)噴氣冷卻。氣冷的冷速不如油冷快，也低于傳統(tǒng)淬火法中的熔鹽等溫、分級淬火。因而，不斷提高噴冷室壓力，增大流量，以及采用摩爾質(zhì)量比氮和氬小的惰性氣體氦和氫，是當今真空淬火技術發(fā)展的主流。70年代后期將氮氣噴冷的壓力從(1～2)%26times;10Pa提高到(5～6)%26times;10Pa，使冷卻能力接近于常壓下的油冷。80年代中期出現(xiàn)超高壓氣淬，用(10～20)%26times;10Pa的氦，冷卻能力等于或略高于油淬，已進入工業(yè)實用。90年代初采用40%26times;10Pa的氫氣，接近水淬的冷卻能力，尚處于起步階段。工業(yè)發(fā)達已進展到以高壓(5～6)%26times;10。Pa氣淬為主體，而中國產(chǎn)氣淬一些金屬的蒸氣壓(理論值)與溫度的關系則尚處于一般加壓氣淬(2%26times;10Pa)型階段。
