Fig. 1 is the structural representation of the metal decking of the anti-laser irradiation of the present invention;
Wherein: the 1-metal substrate; The 2-zinc-impregnating layer; The 3-nickel coating; The 4-Gold plated Layer.
The specific embodiment
Through research extensively and profoundly to raising material surface threshold for resisting laser damage in the superlaser parameter measurement technology; Proposed to improve the process of surface treatment of the anti-laser-damaged threshold value of metal material; And grope through a large amount of experiments, realized concrete processing and fabricating method.
As shown in Figure 1, metal substrate 1 surface sand-blasting is processed with zinc film, nickel film and golden film after being treated to diffuse surface successively, and the material of metal decking is aluminium or copper, and concrete procedure of processing is following:
(1) selected metal decking is carried out high-temperature heat treatment, remove the residual stress of material internal, avoid material in processing and tolerance laser irradiation process, the distortion situation to occur;
(2) metal decking after the heat treatment is cleaned and blasting treatment.For reaching better diffuse effect, the sandblast process comprised for two steps, spray coarse sand and spray fine sand.At first select for use the sand grains about particle 2mm to carry out blasting treatment, select for use the fine sand about 1mm to carry out blasting treatment then.Sandblast need be tested its surface reflectivity and sandblast uniformity parameter after accomplishing, if surface reflectivity reaches more than 80%, and sandblast is more even, then gets into next step operation, otherwise needs blasting treatment once more.
(3) to the metal decking after the sandblast clean, oil removal treatment, remove in the sandblast process in the material surface remaining impurities.Clean in should be about 80 ℃ and the hot water that flow of part after the oil removing, but flush away alkali lye, soap lye, emulsion and silicate;
(4) panel, concentration is carried out the highly basic oxidation in being the sodium hydroxide solution of 10%-30% (weight ratio); The time control of this process should be within 10min; Overlong time can erode sand blasted surface, and the time, too short meeting caused oxidation insufficient, and the sand blasted surface oxidation is inhomogeneous;
(5) panel is removed light in concentration is the salpeter solution of 40%-60% (volume ratio) and handle, the time control of this process should be at 3～5s, and purpose is to remove reflective surface, increases the roughness and the subsequent attachment power of panel surface.
(6) panel is placed on NaOH: Zn is the basic zincic acid salt plating liquor of 10: 1～14: 1 (mass ratio), and each galvanizing time was greater than 30 minutes; The purpose of soaking the zinc processing is the adhesive force that increases follow-up other coating, and dip galvanizing technique generally adopts and soaks zinc twice, finally obtains the strong zinc layer of uniform and delicate, adhesion of 7～11 μ m thickness;
(7) adopt electric plating method that the metal decking that soaks behind the zinc is carried out Nickel Plating Treatment, form nickel coating 3.The purpose of Nickel Plating Treatment is the adhesive force that increases follow-up Gold plated Layer, and thickness is 20～40 μ m, and the final result of this operation is to adhere to the even nickel dam of one deck in the metal surface;
(8) metal decking after adopting electric plating method to nickel plating carries out gold-platedly, makes evenly gold layer 4 of its surface attachment one deck, and the thickness of golden film is 1～5 μ m, finally forms a kind of diffusing characteristic diffuser that both had, the reflecting layer that surface reflectivity is higher again.
(9) utilize that hot clear water fully cleans the workpiece after gold-plated about 80 ℃; Adopt compressed air or nitrogen rapidly with the workpiece after the oxidation, make it air-dry rapidly, it is water stain to avoid the surface to leave.
(10) surface reflectivity is measured, and the reflectivity of said gold-plated back diffuse reflection surface should be greater than 90%.
Metal decking through after the above-mentioned PROCESS FOR TREATMENT has been successfully applied in the superlaser parameter measurement system.Experiment shows that this kind treatment process can effectively improve the threshold for resisting laser damage of metal material, and can be applied in the superlaser irradiation test of thousands of watts/square centimeters of several seconds laser duration, power density.Integrate, the process of surface treatment that this kind improves the metal material threshold for resisting laser damage has that technology is simple, the threshold for resisting laser damage advantages of higher, has solved reverberation causes potential threat to optical element in the light path problem simultaneously.
