高速钢（W6Mo5Cr4V2）滑片（或叶片）的盐浴软氮化处理
摘要：
本发明涉及一种高速钢滑片或叶片的盐浴软氮化处理，其特征在于：由下列组成物及重量百分比组成：NaCNO40％—60％，KCNO 5％—15％，Li2CO33％—10％，K2CO325％—40％，软氮化盐浴液对高速钢滑片或叶片处理方法，清洗：用航空煤油或酒精洗去表面油污及脏物，装卡：选用适合的钢丝网，立放滑片，预热：预热温度350－420℃，时间10－20分钟，处理温度为550℃－590℃，时间15－60分钟。处理时通入氨气或压缩空气，油冷：冷却油须加热至100－160℃，油冷时间为30－120秒，水冷：油冷后直接水冷并清洗5－10分钟(通入压缩空气搅拌)，去油：水冷后浸入含清洗剂的水中去油2－5分钟(通入压缩空气搅拌)，清洗：去油后浸入清水中清洗1－2分钟，抛光：洗净后的工件经震动抛光机抛光40－80分钟。本发明的优点是能使压缩机滑片(或叶片)其耐磨性及使用寿命大幅度提高。
摘要（英）：

The present invention relates to the salt bath tufftriding treatment of high speed steel slide vane or blade. The tufftriding treating liquid consists of: NaCNO 40-60 wt%, KCNO 5-15 wt%, Li2CO3 3-10 wt% and K2CO3 25-40 wt%. The salt bath tufftriding treatment of the high speed steel slide vane or blade with the tufftriding treating liquid includes the following steps: cleaning with aviation kerosene or alcohol; mounting vertically on proper steel wire net; pre-heating at 350-420 deg.c for 10-20 min; treating at 550-590 deeg.c for 15-60 min while introducing ammonia or compressed air; 100-160 deg.c hot oil cooling for 30-120 sec; water washing and cleaning for 5-10 min; eliminating oil via soaking in water containing detergent for 2-5 min and soaking in water for 1-2 min for cleaning; and polishing in a vibrating polishing machine for 40-80 min. The present invention can raise the antiwear performance and prolong the service life of slide vane or blade of compressor.
