Background technology
Laser temperature shot-peening is a kind of novel surface strengthening treatment technology, can reach the surface strengthening effect more excellent than mechanic shot peening.The surge pressure of induced with laser generally needs just can reach good shot blasting effect by the constraint of restraint layer.The most frequently used restraint layer of room temperature laser peening is flowing water, but flowing water can produce bubble even vaporization at a higher temperature, so the conventional flowing water restraint layer of laser peening can not be used for laser temperature shot-peening.The surge pressure how effectively retraining induced with laser at a higher temperature has become the focal issue of mechanical association area.The constrained procedure that current laser peening is conventional has flexible constraint and rigid constraint.
Flexible constraint, mainly utilizes flexible media to retrain the pressure that laser peening produces, and comprises flowing water constraint, high pressure gas constraint and flexible lamina constraint.Flowing water retrains, and is the flowing water layer manufacturing one deck 1 ~ 5mm at matrix surface, utilizes flowing water layer percussion pressure to retrain.The such as patent No. is the patent application of CN102212655A, propose a kind of laser shock method, use moisture film as restraint layer in laser-impact process, this constrained procedure can play the effect of constraint at normal temperatures to induced with laser pressure, but flowing water restraint layer is not suitable for the higher occasion of temperature due to lower boiling point.Flexible lamina, paste the flexible materials with binding effect at matrix surface to realize constraint, the such as patent No. is the patent application of CN1404954A, propose a kind of flexible lamina for laser-impact process, the method utilizes silicone gel material to be made into flexible lamina, cover matrix surface and realize constraint, but there is some deficiency following: (1) silicone gel material at high temperature melts as liquid state, be easy between pad pasting and matrix in laminating process enter air, so dissolve rear formation bubble, reduce binding effect; (2) plasma body extreme temperatures in laser-impact process, silicone gel material easily burns, and reduce binding effect, security is not high.Gas retrains, be utilize gas to produce at material surface high pressure as constraint, the such as patent No. is the patent application of CN102560079A, it proposes a kind of take high pressure gas as laser shock peening method and the device thereof of restraint layer, the method adopts high pressure gas continuous injection to matrix surface, induced with laser surge pressure is retrained, this method can play the effect of constraint at normal temperatures, but also there is following shortcoming: (1) high pressure gas is known from experience affects the cohesion of plasma body at matrix surface, reduce induced with laser surge pressure; (2) high pressure gas knows from experience the temperature obviously reducing matrix surface continuously, thus the method is not suitable for the occasion of laser temperature shot-peening.
Rigid constraint, is mainly retrained induced with laser pressure by rigid transparent medium, at present mainly glass, such as K9 glass.The such as patent No. is the patent application of CN102492805A, propose a kind of method and apparatus adopting the laser impact intensified metallic substance of deep cooling, the method adopts K9 glass to retrain induced with laser pressure as restraint layer in laser-impact process, although this method can play binding effect under normal temperature and low temperature, but also there is following shortcoming: the surge pressure that (1) produces due to induced with laser easily produces stress concentration on glass, thus cause glass cracks even breaking, reduce shot blasting effect; (2) K9 glass at high temperature can produce softening effect, more easily cracks and even ruptures, thus causes the effect of shot-peening to reduce.
With the present invention relatively for the patent No. be the patent application of CN103143836A, the flowable liquids utilizing the pump housing to carry in this patent application is as restraint layer, this method goes for the laser peening under normal temperature, but for laser temperature shot-peening, resistant to elevated temperatures transparent liquid is less, as conventional silicone oil, owing to having high viscosity, general vane pump is difficult to realize its conveying, and high-power ram pump is expensive and adjustment is difficult, is difficult to the production requirement meeting variant production.
