摘　　要：采用超音速电弧喷涂技术,在锅炉受热面常用钢材T91钢表面制备出耐磨损的复合涂层。对制备的耐磨涂层进行了涂层结合强度实验、XRD分析和涂层高温冲蚀实验,实验结果表明:采用超音速电弧喷涂技术制备出的耐磨涂层,不仅具有较高的耐磨性而且具有优异的抗高温冲蚀性能,适用于锅炉高温受热面的防护。为锅炉设备的受热面采用防磨涂层提供了理论依据。An abrasion-resistant composite coat on the heating surface of a boiler made by using commonly-used steal material T91 was prepared by adopting the supersonic electric arc spraying technology,A bonding strength test,XRD analysis and high temperature erosion test of the coat under discussion were conducted. The test results show that the new type composite coat boasts an excellent high temperature erosion-resistant performance,thus applicable for protection of high temperature heating surfaces in boilers
