Description
Technical field
The invention belongs to laser impact intensified fields, refer in particular to a kind of laser-impact dress of automatically replaceable glass restraint layer
It sets.
Technical background
Reiforcing laser impact technology is to make it using the absorbed layer on the short-pulse laser impact material surface layer of high-energy density
Plasma simultaneously generates explosion and strong shock wave in material surface and internally propagates, and makes material surface certain area
It is interior to generate plastic deformation and complicated dislocation structure, certain thickness residual compressive stress layer is formed, the fatigue strength of part is improved
And resistance to corrosion.This technology is widely used in many necks such as machine-building, air harbor day, microelectronics, national defence, medical treatment at present
Domain.
During short-pulse laser shock peening, in order to inhibit the free diffusing of plasma, more concentrated, more
Prolonged shock wave, it will usually add one layer of restraint layer in laser processing area.Common constrained layer material has K9 glass, soft
Property film and water etc., wherein water because it is at low cost, flexible, adaptable the features such as obtained most commonly used use, but wherein
One important disadvantage is that the rigidity of water layer is insufficient, is difficult to provide powerful restraining force compared with glass.Glass restraint layer can be big
Amplitude improves shock wave pressure and impact, but big there is also consuming, of high cost, replaces troublesome problem.
There are mainly two types of existing glass restraint layers, and one is directly use monolithic glass adding as constraint lamination workpiece
Work surface；Another kind is compound constant layer, and lower layer is moisture film, and upper layer is glass cover-plate, improves flow restraining force.Both modes
Respectively have a feature, former scheme realize it is simple, it is with obvious effects, can obtain more smooth finished surface, but system of processing
Flexibility ratio is general, and the accumulation damaged after certain number impact may result in rupture, need to replace manually；And in another scheme
Glass, which is overlying on moisture film, is used as compound constant layer, and the cushioning effect of water reduces broken risk, while restriction ability also obtains
It must significantly improve, but this compound constant layer device is complicated, of high cost, maintenance difficulties are big, and its drop point is deposited with laser beam
In certain distance, therefore when handling the part of certain shapes, it may be difficult to reach the best fit point of laser beam and moisture film.
