某种煤压机叶片表面防腐涂层的制备及性能研究

文章介绍了某种燃机的煤气压缩机叶片使用工况，研究了煤压机叶片涂层的制备方案．确定在叶片的叶身表面制备DF-1涂层，在叶柄表面制备Ni—P涂层。研究了涂层的生产制作工艺流程、质量控制要点和涂层的性能．发现叶身表面DF-1涂层具有耐腐蚀性能优异，结合力高，表面光滑等特点；叶柄表面Ni—P涂层具有优异的耐蚀性和耐磨性。最后此种涂层成功应用于新旧燃机机组的压缩机叶片表面防腐生产．

Study on Preparation and Properties of Anti-corrosion Coating on Compressor Blade Surface of Gas Turbine

This paper introduced the working condition of the compressor blade which belonged to the gas turbine, researched the preparation method of the blade coating, and finally determined that the DF-1 coating was made on the surface of the blade body, and the Ni-P coating was made on the surface of petiole. The coating production process, the quality contrnl point and the performance of the coating were studied. It was found that the DF-I coating had excellent corrosion resistance, high bonding strength, smooth surface, and the Ni-P coating of petiole surface had excellent corrosion resistance and abrasion resistance. Now these coatings had been used successfully on the compressor blade of the gas turbine unit.
