摘　　要：利用普通离子渗氮炉进行了膏剂离子渗铬。试验结果表明：该方法具有渗层形成速度快，工艺简单，易操作等优点。在大量试验的基础上，优选出了渗铬膏剂的配方，并且研究了提高渗铬层硬度的方法。利用优选出的膏剂对45钢进行膏剂离子渗铬，在950℃×2h条件下，可获得140μm厚的渗层。Paste ion chromizing by ion nitriding furnace was introduced. Reaults showed that Merits of this chromizing method were chromizing layer forming fastly,processing simplely and operating easily. On the basis of a series of tests,the optimum paste was obtained and the way to enhance hardness of the layer was studied. After paste ion chromizing under the condition of 950℃×2h,the depth of chromized layer of steel 45 can reach 140μm.
