Description
Technical field
The present invention relates to physical process and manufacturing field, refer in particular to and utilize high-energy, short pulse laser beam to be the laser continuous collision reinforcement metallic substance of energy or a kind of device and method of workpiece.
Background technology
Reiforcing laser impact technology utilizes high power density, short-pulse laser irradiation metal material surface exactly, form the plasma body high-pressure shocking wave in its surface (or coating), make the part material top layer produce the residual compressive stress of plastic deformation and hundreds of MPa, thereby improve the anti-fatigue performance of metal, prolong the part purpose of fatigue lifetime to reach.
The early stage applied research of laser impact intensified treatment technology originates from the attention of the sixties in last century to aircraft structure reliability and security.The key position of aircraft, for example typical stress concentration structure---fastening piece aperture on the aircraft very easily produces fatigue cracking under the effect of repeated load, and tired source crackle is many from fastening bore edges germinating.Therefore, in material selection and structure design manufacturing, how to eliminate the disadvantageous effect of key position stress concentration as far as possible, improve the anti-fatigue performance of aircraft structure, increase the service life, guarantee the reliability of aircraft and the important topic that security is airplane design and investigation of materials person.The antifatigue intensifying technology that is widely used at present aircraft structure both at home and abroad has two kinds: shot-peening and cold extrusion.They are effectively concerning big area is strengthened, but for the position (below φ 3.5mm) of reduced size, shot-peening and cold extrusion all are difficult to even can't carry out, and strengthening effect is also undesirable.In the case, laser impact intensified treatment technology becomes the potential alternative techniques with its pinpoint characteristics.
Although all are engaged in the scholar and the aviation of reiforcing laser impact technology research and make the potential that reiforcing laser impact technology is recognized in the commercial city, although reiforcing laser impact technology is applied to strengthen the experimental study of aeronautical material and passed by nearly 40 years, but have only U.S. labor human relations Slipher, Vesto Melvin More to cooperate at present, successfully reiforcing laser impact technology is applied to the intensive treatment of jet blade and gear with MIC company.Its major cause is must use constraint medium and coated material in the laser impact intensified process, otherwise the strengthening effects no matter laser power is much, the many weak points of pulse also can't reach expection.Therefore we can say that the research of carrying out the selection of laser-impact constrained layer material is that can reiforcing laser impact technology obtain the aircraft industry key in application fast.
Along with the high speed development of laser apparatus production technology, utilize the high-energy short-pulse laser just can produce very high-octane laser beam, power density can reach 10
9～10
21W/cm
2More than.It acts on and makes its gasification impact generated by explosion crest value pressure can reach tens～hundreds of GPa on the energy transfer medium (liquid or gas), then can produce the residual compressive stress of a hundreds of MPa on the metallic substance top layer.But in laser impact intensified technological process, because restraint layer and coated material are the technology materials that must have, their existence has greatly increased to swash puts, to guarantee strengthening effect.But the existence that adds gripping unit has limited laser impact intensified range of application and production efficiency etc. greatly.In order to make laser impact intensified being more widely used, in laser impact intensified, use and a kind ofly can play effective increase laser blast wave peak pressure, be suitable for impacting the various planar piece surfaces that are similar to, and restraint layer medium that need not clamping has become the gordian technique difficult problem of laser-impact industrial applications.
Though reiforcing laser impact technology has obtained certain application in the US Airways field, its employed constraint medium is a water, during shock peening is to allow the liquid water workpiece surface that continued to flow.Easily form some little eddy current or small bubbles here when the key issue of Cun Zaiing is current process workpiece or material surface, intense laser beam is easily formed the light beam focusing effect, thereby influence the laser-impact effect.
Meanwhile their the laser-impact coating of use is to apply in advance or be sprayed on to treat the impact zone surface, and the ready-formed coating is difficult to control its thickness, and coated and dried also needs certain hour, also needs secondary to remove after the shock treatment, and the laser-impact overall efficiency is not high.
Therefore, research is a kind of will retrain the laser impact intensified device that medium and coating gather together and become the gordian technique that can laser realize industrial applications.
