A way to manufacture inserts for steam cooled hot gas path components
摘要：
A method for forming inserts for steam cooled hot gas path components involves casting the inserts (10) and laser drilling (14) the cast inserts (10) with the ceramic casting core (12) still in place. Thereafter, the ceramic core (12) is removed through the use of a leachant. By laser drilling (14) the holes (16) with the ceramic core (12) still in place, the ceramic core (12) acts as a backer during the laser drilling (14) which results in more precise drilling of the inserts (10) and reduced processing time.

一种用于蒸汽成形刀片方法冷却的热气体路径部件涉及一种浇注的插入件（10）和激光钻孔（14）铸造插入件（10）与陶瓷铸芯（12）代替在休息。 那里之后，所述陶瓷芯（12）通过使用浸出剂的除去。 通过激光钻孔（14）中的孔（16）与所述陶瓷芯（12）代替休息，所述陶瓷芯（12）作为所述激光钻孔（14），这导致在插入片段的更精确的钻孔期间背衬（10 ），并减少处理时间。
