Description
The invention belongs to the device of preparation particles reiforced metal-base composition.
Spray co deposition is a kind of technology of novel preparation particles reiforced metal-base composition, and it has enhanced granule and is evenly distributed, and matrix is the rapid solidification feature, and the output advantages of higher.Its ultimate principle is: introduce enhancing and common deposited formation blank in the metal melt atomised jet stream.The key of technology is: in order to make the enhanced granule uniform distribution, must quantitative it be fed through injection stream, and be deposited layer institute and catch.Because enhanced granule is a powdered form, exist certain particle to distribute, common Pneumatic conveyer is difficult to realize quantitative control, makes enhanced granule at the matrix skewness, has a strong impact on the tissue and the performance of deposit preform.
The object of the present invention is to provide a kind of spray co deposition device, utilize this device can prepare large-scale jet deposition particulate reinforced composite, enhanced granule quantity can strictness control and be evenly distributed in a big way.
The present invention is made up of powder apron quantitive conveyor structure and jet deposition mechanism, described powder apron quantitive conveyor structure comprises the hopper of splendid attire enhanced granule, the screw rod feed appliance of tape-controller, negative pressure chamber, band is defeated, the negative pressure generator of the body of supplying gas inlet and transport pipe, the inlet of the outlet of hopper and screw rod feed appliance joins, the outlet and the negative pressure chamber of screw rod feed appliance join, negative pressure chamber and negative pressure generator join, described jet deposition mechanism comprises the compound spray gun that band enhanced granule inlet and atomizing gas enter the mouth, the multi-layer spray deposition device, aforementioned transport pipe and enhanced granule inlet join.
As follows below in conjunction with description of drawings enumeration of the present invention:
Fig. 1 is the structural representation of powder apron quantitive conveyor structure of the present invention
Fig. 2 is the structural representation of jet deposition of the present invention mechanism
The enhanced granule spray co deposition device of mobile crucible automatic control of the present invention can be divided into two portions, one is a powder apron quantitive conveyor structure, be used for carrying enhanced granule 8, as shown in Figure 1, it comprises hopper 1, screw rod feed appliance 2, the controller 3 of screw rod device, negative pressure chamber 7, negative pressure generator (class atomizer structure) 6,4 is delivering gas inlet and transport pipe 5.It two is a jet deposition mechanism, and as shown in Figure 2, it comprises compound spray gun 10, enhanced granule inlet 9, and the transport pipe 5,11 of map interlinking 1 enters the mouth for atomizing gas, and 12 is the multi-layer spray deposition device.
Delivering gas with certain air pressure produces a negative pressure by inlet 4 by negative pressure generator 6 in negative pressure chamber 7, to all suck by the enhanced granule that screw rod feed appliance 2 is imported, enhanced granule is under the carrying under one's arms of high speed delivering gas stream simultaneously, be delivered to inlet 9 by transport pipe 5 suspensions, enter atomized liquid stream, common deposited makes matrix material jet deposition pipe, ingot blank by multi-layer spray deposition device 12 on blank.The operational throughput of enhanced granule can be measured different sorts, different grain size particle sendout and screw speed relation curve in advance by controller 3 accurate quantifications control, just can be according to the preparation of the matrix material of these curve design difference enhanced granule content.This device can be carried various wild phases, as SiC, Al
2O
3Deng, even over-spray powder can both be sent smoothly with this device.Enhanced granule can continuous supplementation to hopper, also can adopt two hoppers and screw rod to be used alternatingly, to realize the continuous conveying of hundreds of kilograms of wild phases.
Utilize aforesaid device can prepare large-scale particle and strengthen the jet deposition matrix material, processing parameter mainly contains: the shape of the rotating speed of the kind of enhanced granule and granularity, screw rod, the air pressure of delivering gas and airshed, delivery conduit and length and jet deposition parameter.
The enhanced granule spray co deposition device of mobile crucible automatic control of the present invention has following characteristics: 1) can accurately carry enhanced granule, enhanced granule is evenly distributed in the matrix, has increased substantially performance of composites.2) adopted the combined type spray gun, enhanced granule all enters atomizing cone, is deposited layer and catches, and has improved the utilization ratio of enhanced granule.3) enhanced granule can be carried continuously, and operational throughput can accurately be regulated in a big way, can control the percentage composition of wild phase in the deposit preform, is suitable for suitability for industrialized production.4) conveying of enhanced granule is not subjected to the restriction of kind, carry when can adopt a plurality of screw rod feed appliances to realize multiple enhanced granule, thereby the jet deposition matrix material for preparing multiple strengthening phase, and the amount amount of sending of the defeated enhanced granule of each feed appliance unit time can be by the speed adjustment of screw rod, to regulate the ratio of each strengthening phase.5) equipment is simple, and is easy to operate.
