| 摘 要： | 为提高低温螺旋榨油机榨螺的使用寿命，采用爆炸喷涂工艺，在榨螺的表面制备WC-12%Co耐磨涂层，对涂层的相组成和形貌进行了分析，对涂层的硬度及其与基体的结合强度进行了测定，并与传统榨螺的试样进行了磨料磨损对比试验。结果表明，该涂层具有良好的力学性能，WC-12%Co爆炸喷涂涂层使用寿命是传统榨螺渗碳淬火层的4.2倍。

| Abstract: | In order to improve the useful life?of screw surface of low temperature screw presser, the WC-12%Co wear resistant coat was prepared on the surface of screw by the detoratiom spraying?process. The phase composition and microstructure of the coat were analyzed, and the microhardness of the coat and adhesion strength between the coat and the substrate were measured and tested. And the contrast wear resistant tests between detoratiom spraying?coating screw specimen and traditional screw specimen wree done and the results showed that the WC-12%Co detonation spraying coat possessed excellent mechanical properties?and the using life of the WC-12%Co detonation spraying coat reached 4.2 times the using life of traditional carburizing and quenching coat. |
