钛合金叶片阻尼台堆焊层铸造碳化钨颗粒分布不均匀因素分析

Factor analysis of uneven distribution of tungsten carbide particles in surfacing layer casting on damping platform of titanium alloy blade

摘要: 各类发动机转子叶片是典型的钛合金零件之一,在使用过程中,需要对发动机转子叶片阻尼台端面进行耐磨性能强化处理.而在对叶片阻尼台钎焊铸造碳化钨(W C)耐磨涂层进行强化时,铸造碳化钨(W C)颗粒分布情况将直接影响堆焊层的质量,进而影响叶片的使用寿命.为此,通过对感应钎焊原理进行分析,总结出焊接过程中铸造碳化钨(WC)颗粒分布不均匀的原因,并给出了详细的建议,供同行参考借鉴.

Abstract: The engine rotor blades are commonly made of titanium alloy.When brazing the engine rotor blade damping table to strengthen the wear resistance,it is crucial to consider the particle distribution of the cast tungsten carbide(WC).This distribution directly influences the quality of the surfacing layer and subsequently impacts the blade's service life.Thus,in order to enhance the wear resistance of the rotor blade damping table,attention must be given to the particle distribution of the cast tungsten carbide(WC).
