The invention provides a device and method for conducting superfast laser machining of an air film hole in a water jet environment. The device comprises a three-shaft moving workbench system, a superfast laser device, a water jet circulating device and a control system. A to-be-machined sample is fixed into a water container through a specific clamping device. The water container is fixed to a three-shaft moving workbench and connected with a water tank through a drainage pipe. Medium water is pumped out of the water tank through a water pump and flows through a water injection pipe and onto the surface of the to-be-machined sample through a water jet nozzle. Laser transmitted by the superfast laser device penetrates a water jet film and is focused onto the surface of the to-be-machined sample for machining. By means of the device and method, the advantages of traditional air and underwater laser perforating are combined; machining efficiency of superfast laser perforating is guaranteed, and microcracks on the surface of the to-be-machined sample and the inner walls of micro-holes are reduced; accumulated slag and a recasting layer are eliminated; and the geometrical morphology precision of the sample is improved.
Description
technical field [0001] The present invention relates to the technical field of ultrafast laser processing, in particular to an ultrafast laser processing device and method for air film holes in a water jet environment, and in particular to an ultrafast laser processing device and method for air film holes in a blade with a thermal barrier coating in a water jet environment. Laser processing method and device. Background technique [0002] With the rapid development of aerospace technology, the use of metal materials alone can no longer meet the requirements for use in high-temperature environments. For example, nickel-based single crystal blades need to increase the working temperature of turbine blades by adopting film cooling structures and preparing thermal barrier coatings on the surface. Coating ceramic thermal barrier coatings (thermal barrier coatings for short TBCs) on the surface of gas turbine engine blades can achieve the effect of heat insulation and reduce the ...
