研究了TRT叶片腐蚀磨损的原理，选择合适的材料，采用合理的喷涂方式，通过实验表明，试样1(Co-87WC)涂层是抗冲蚀磨损的最佳选择，而试样4涂层(TiN)则不适合TRT叶片的使用环境。%The mechanism of TRT blade corrosion and wearing was studied. Experi-ments showed that the coating sample 1 (Co-87WC) with selected suitable material and ap-propriate coating method was the best choice for resistance to impact corrosion and wearing, while the coating sample 4 (TiN) was unsuitable for the service condition of TRT blades.
