Description
Technical field
The present invention relates to the treatment technology of spray-on coating, particularly a kind of spray-on coating coupling post-treating method.
Background technology
The coating formed through spraying sprays to matrix at a high speed by melted state powder particle, hot spray coating forming process determines the constructional feature of coating, spray-on coating is by the interlaced lamellar structure's structure be stacked in wave of infinite variety particle, some holes and cavity is inevitably there is between particle and particle in coating, and with oxide inclusion, and be mechanical bond between coating and base material, thus have impact on and the bonding strength of metallic matrix and upper layer density, therefore, be difficult to adapt to comparatively rugged environment, which has limited its range of application and work-ing life.The defect of this coating texture just, makes change the tissue of coating by the aftertreatment of coating or carry out suitably regulating becoming possibility, for the performance finally improving coating brings great potential to original tissue.Existing post-processing technology mainly contains laser remolten, electron beam remelting, TIG remelting, flame remolten, overall heating remelting and inducting remolten etc.Rear molten process utilizes thermal source ingredient melting by what the most easily melt in alloy, and the liquid phase of generation contributes to the strengthening of diffusion process and the infiltration of composition.The result of fusing makes the land of spray-on coating and matrix become densification from originally stacking lamellar structure and organize more uniformly, and hole minimizing even disappears.Therefore, adopt suitable re melting process, the bonding strength between coating and matrix and coating inner quality can be improved, thus improve wear-resisting, the solidity to corrosion of coating.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of spray-on coating coupling post-treating method, makes spray-on coating can adapt to work under rugged environment, improves range of application and the work-ing life of spray-on coating.
The technical solution adopted in the present invention: a kind of spray-on coating coupling post-treating method, first inducting remolten is implemented to spray-on coating previously prepared on workpiece, the alternating magnetic field in induction coil is utilized to produce eddy current within the workpiece, the heat that eddy current produces makes spray-on coating soften, and ensures the Heating temperature of spray-on coating more than spray-on coating alloy solidus 10 ~ 30 DEG C; Then, carry out ultra-magnetic telescopic ultrasonic surface intensive treatment to spray-on coating, amplitude controlling is in 5 ~ 10mm scope, and precompression controls at 50N ~ 350N.
Received current 8A ~ the 80A of described induction coil, output rating 5KW ~ 50KW, oscillation frequency 15 ~ 35KHz.
In the present invention, spray-on coating reheats certain temperature (more than spray-on coating alloy solidus 10 ~ 30 DEG C), (in spray-on coating, there are the liquid state of 60% ~ 80% and 20% ~ 40% solid-state) when now spray-on coating is semi-solid state, fast the strengthening of ultra-magnetic telescopic ultrasonic surface intensifying technology adopted to spray-on coating.Ultrasonic surface intensifying technology is different from traditional surface treatment (shot-peening, Supersonic particulate etc.), and ultrasonic surface processing treatment mainly relies on the static pressure that is applied to machining tool head and overclocking mechanical vibration to make material generation microcosmic plastoelastic deformation.Conventional for ultrasonic introducing is rolled extrusion process, to the following aspect of spray-on coating improved performance effect main manifestations: ultrasonic crowded roll extrusion can realize the nanometer of spray-on coating, the nanocrystalline structure of the axles such as formation, grain orientation stochastic distribution, form highdensity dislocation simultaneously, compare with initial grain size, crystal grain obtains refinement significantly; Ultrasonic edging pressure introduces unrelieved stress.The same with traditional surface deformation strengthening, the ultrasonic coldworking strengthened that rolls also can produce residual compressive stress, it has roll extrusion and shot-peening multiple strengthening effect, but because metal surface receives driveing and extruding of the outer tool heads of ultra-magnetic telescopic device, metal is subject to inner metallic layer to surrounding expansion simultaneously and pins down generation tensile stress, top layer produces stress, and along with the increase of squeeze and the increase of extrusion passes, workpiece unrelieved stress absolute value totally increases; Ultrasonic crowded roll extrusion can improve the mechanical property of material surface.Make the viscous deformation of spray-on coating occurrence of large-area, uniform texture refinement, hole and cavity is there is between particle and particle in lamellar structure's structure in elimination spray-on coating and coating, improve the unrelieved stress degree of depth simultaneously, hardened in top layer, fatigue resistance and the suppression crack initiation ability of workpiece are improved.
The present invention constitutes the main advantage of induction heating by the skin effect of the eddy current of coating inducting remolten technology, and heat can be concentrated in the coating area of requirement heating.Utilize the characteristic that coating yielding stress reduces under ultra-magnetic telescopic ultrasound condition, adopt strengthening tool heads, certain static pressure and overclocking mechanical vibration are applied to workpiece, main dependence is applied to the static pressure of machining tool head and overclocking mechanical vibration make coating generation microcosmic plastoelastic deformation, suppress the generation of microdefect in coating aftertreatment, obtain the high-quality spray-on coating being satisfied with heterogeneous microstructure and performance.
Adopt the present invention to implement aftertreatment to spray-on coating, spray-on coating can be made to improve more than 8 times a work-ing life, and can reconditioning 4 ~ 5 times, entire life improves 40 ~ 90 times than other spray-on coating.
