针对风机叶片耐磨性差和寿命低等问题,提出采用火焰喷焊法在20~#钢基体上涂覆204钴基合金,以获得坚硬和耐磨的合金覆层。试验结果表明,利用这一技术可使风机叶片的使用寿命提高8倍以上。
Aiming at the problems of poor wear resistance and low life of fan blades, a flame spray welding method was proposed to coat 204 Co-based alloys on 20 ~ # steel substrates to obtain hard and wear-resistant alloy coatings. Test results show that the use of this technology can make the fan blade life increased by 8 times.
