Abstract
部品(10)の表面孔(12)からセラミック堆積物(22)を除去する方法、具体例として、冷却孔(12)を備えた部品(10)の表面(16)に堆積したセラミック皮膜(20)の一部を除去する方法を提供する。
【解決手段】
本方法は、冷却孔(12)周囲のセラミック皮膜(20)の層間剥離、亀裂その他の損傷も避けられるパラメータで動作させたパルスNd:YAGレーザを用いる。レーザは、セラミック堆積物(22)の一部を孔(12)から除去しつつ、セラミック堆積物(22)の残存部分によって孔(12)周囲に表面開口が画成されるようなレーザビーム(24)を発振するように動作させる。具体的な動作パラメータとしては、約2Hz〜約20Hzのパルス周波数及び約0.25ミリ秒〜約6.0ミリ秒のパルス幅が挙げられる。
