Background technology
Composite pressure vessel is the important component part of space system mover, and its purposes is that the geseous fuel that solves in the aerospacecraft carries problem.Because composite pressure vessel has not only been taken into account good workability, resistance to air loss, solidity to corrosion and the characteristics such as HS, H.T. of metal inner lining; Combine again that matrix material is in light weight, security good and good advantages such as designability; Compare with pure all-metal pressurized vessel, composite pressure vessel has that texture quality is light, physical dimension is selected flexibly, security and distinguishing feature such as safety is high, corrosion-resistant, fatigue performance is good.The container performance factor is high, is about 1.5～3 times of titanium alloy; Under same volume and pressure condition, can save the quality of titanium alloy cylinder about 25%～50%; The loaded work piece life-span is long; Highly reliable; Productive expense is low, the cycle is short.
Traditional composite pressure vessel structure generally is made up of metal inner lining layer (duraluminum or titanium alloy), fiber winding layer.The metal inner lining layer is used for storing liquid fuel, and main effect is airtight, anticorrosion, heatproof and withstand voltage.Outer use fiber twines strengthens the property.Main effect is to guarantee that pressurized vessel under stressed situation, has enough intensity, rigidity and stability.The researchist all is being devoted to reduce on the thickness of inner lining direction on the loss of weight both at home and abroad at present; But as the duraluminum that carries liner; Supporting capacity is very little, receives the restriction of complete processing simultaneously, the current composite pressure vessel of thickness of inner lining about 1-2mm that generally can only produce; Therefore, its quality is still very heavy.
Summary of the invention
The present invention seeks to provides a kind of method of electrical arc spraying method for preparing PbSn alloy lining composite pressure vessel in order to solve the overweight problem of quality of existing composite pressure vessel.
The inventive method may further comprise the steps:
Step 1, with the core of pressurized vessel shape-consistent on preparation be soaked with the thomel wound composite winding layer of epoxy resin;

Embodiment
Embodiment one: below in conjunction with Fig. 1 this embodiment is described, this embodiment method may further comprise the steps:
Step 1, with the core of pressurized vessel shape-consistent on preparation be soaked with the thomel wound composite winding layer of epoxy resin;
Step 2, prepare the resin transition layer of doping metals powder at the inwall of thomel wound composite winding layer;
Step 3, the resin transition layer of fiber winding layer and the doping metals powder of preparation is solidified;
Step 4, the resin transition layer inwall after curing adopt the electric arc spraying mode to prepare the pressure container inner lining layer.
The process that the step 1 preparation is soaked with the thomel wound composite winding layer of epoxy resin is:
Step a, thomel is immersed in the epoxy resin, let carbon fiber surface fully be stained with epoxy resin; Select the TDE85 epoxy-resin systems in this embodiment for use.
Step b, with the core of pressurized vessel shape-consistent on the thomel that is soaked with epoxy resin with [0/90/45/90/0]
nMode is spread layer, and n is a natural number, 1＜n≤4,
Behind n shop layer of process, remove core, form thomel wound composite winding layer.
The thomel winding layer plays certain airtight provide protection.It is the gas shield layer of storing.With [0/90/45/90/0]
nIt is to pass through optimization design that mode is spread layer, can obtain good airtight provide protection.
The adulterated metal-powder of step 2 is the Ni powder; The process of the resin transition layer of preparation doping metals powder is: with the Ni powder: epoxy resin is the mixed of 1:3 with the mass ratio; Inwall at thomel wound composite winding layer applies as transition layer then, and coating thickness is 100 μ m～200 μ m.
The benefit of preparation transition layer has 2 points:
Excessive temperature is destroyed the carbon fiber layer that is soaked with epoxy resin when 1, preventing electric arc spraying.
In spraying process; The melt metal particle temperature can reach more than the 6000K; And owing to the epoxy resin cracking temperature on thomel winding layer plywood surface has only about 500K; Pyritous molten metal particle because temperature is too high, can produce breakoff phenomenon to the resin of substrate surface when striking thomel wound composite winding layer (that is: the substrate) surface that is soaked with epoxy resin.So, be at the resin transition layer of fiber winding layer plywood surface preparation doping metals powder;
2, produce certain diffusion phenomena between adulterated metal-powder and the melt metal particle; Make the combination between coating and the matrix change metallurgical binding and the coefficient result of mechanical bond into, can improve the bonding strength between Bulk coat and the substrate by single mechanical bond.
Molten drop Heating temperature, projection velocity are high during all than flame plating, so the kinetic energy of particle and heat energy is all than higher, thus acquisition higher binding strength and strength of coating.
Step 3 solidified process is: the thomel wound composite winding layer that will be coated with the epoxy resin transition layer is put into baking oven, and it is 40 ℃ that oven temperature is set, and keeps 2 hours; In 8～10 minutes, be warming up to 80 ℃ then, kept 2 hours; In 8～10 minutes, be warming up to 120 ℃ then, kept 2 hours; In 8～10 minutes, be warming up to 140 ℃ then, kept 2 hours, curing molding takes out.
Step 4 in the process that resin transition layer inwall adopts the electric arc spraying mode to prepare the pressure container inner lining layer is:
Electric arc spraying is to utilize the ZnAl alloy of sending to continuously as consumable electrode; ZnAl alloy heat fused is become molten drop, and molten drop forms the molten particles bundle under high pressure gas promote, and this molten particles bundle high-speed impact is to surperficial through pretreated transition layer; In the transition layer surface deformation; Be frozen into particle layer, laminate on the particle layer that molten particles afterwards continues formerly to solidify, form the pressure container inner lining layer.
The electric arc spraying parameter is: spray voltage is 30V～80V, and spraying current is 200A～400A, atomization air pressure 0.1MPa～2MPa, spray distance 50mm～200mm.
