发明名称 METHOD FOR MAKING AND REPAIRING EFFUSION COOLING HOLES IN CUMBUSTOR LINER
摘要 A method for making or repairing a laser drilled hole in a component of gas turbine engines, to meet requirements of air flow through the hole, includes deformation of an excess material melted during the laser drilling process and remaining around an opening end of the hole, thereby causing a marginal reduction in an effective diameter of the hole.
