    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.
