摘要

排气阀阀座表面是由于机械和热应力而缓慢降解的表面。对于阀门的新材料和阀门生产技术的改进进行了广泛的研究。本文讨论了制备Fe3Al金属间相填充金属的方法和对H9S2钢阀门阀座表面进行TIG堆焊的方法，并对堆焊参数的影响进行了评价。使用工业射线照相测试(RT)根据质量评估所产生的硬面堆积。

APPLICATION OF FE3AL INTERMETALLIC PHASE FILLER METAL IN VALVE SEATING FACE HARD FACING

The exhaust valve seat face is a surface that degrades slowly as a result of mechanical and thermal stresses. There is extensive research on new materials for valves and for the improvement of valve production technology. This paper discusses the method of obtaining a filler metal made of Fe3Al intermetallic phase and the method of TIG hard-facing on a valve seating face made of H9S2 steel, evaluating the effects of essential hard-facing parameters. The resulting hard-facing build up was assessed in terms of quality using industrial radiography testing (RT).
