Abstract
The novel method that a kind of foamed metal is made belongs to hi-tech, metal new material technology field.It is skeleton that the present invention adopts urethane foam, make foamed metal with electrochemical method, changed the production technique of the powder metallurgic method that prior art adopts, casting etc. fully, it is simple to have processing unit, applied widely, porosity is high, in light weight, feature such as pore diameter range is big, intensity is big, good processability, corrosion resistance are good.
Description
The invention belongs to the high-technology metal field of new.
Foamed metal is a kind of functional material of development in recent years, and its production method has powder metallurgic method, casting etc., and these main drawbacks of producing the foamed metal method are: 1, complex process; 2, equipment complexity; 3, porosity is low; 4, the aperture should not be controlled; 5, corrosion resistance nature is low.
The objective of the invention is to, change fully present production technique and production method, under normal temperature, condition of normal pressure, adopt electrochemical method to make foam metal material.The material scope that is suitable for the inventive method making foam metal material is wide: copper, nickel, iron, silver, chromium, molybdenum, cobalt, tungsten and alloy thereof etc.Electrochemistry is made foam metal material, comprises that electrotyping process treatment process and calcination burn clean technology, is characterized in that:
1, on the urethane foam skeleton, uses the electrotyping process treatment process.
That is: electrotyping process solution temperature T=10～90 ℃.
Current density D
K=1～40A/dm
2
Treatment time t=1～12h.
The working electrode area with supporting electrode area ratio is: 1: 2～4.
2, calcination sintering process:
Temperature T=500～1200 ℃.
Time t=0.5～2h.
Furnace atmosphere: H
2
The invention has the advantages that:
1, technology is simple, and equipment is simple.
2, porosity height (〉=98%), existing technology 15%～80%.
3, in light weight, have only 1/10～1/50 of compact metal material.
4, pore diameter range big (0.05～number mm) prior art 0.1～several mm.
5, have the almost consistent three-dimensional shape skeleton that connects continuously of thickness, than the material that existing method is produced, notch effect is low, and stress concentration is little, and higher physical strength and anti-fatigue performance are arranged.
6, good processing properties: can be crooked, machining, cutting stretches, and reels bonding, compression, eutectic welding knot, soldering etc.
7, because skeleton is fine and close, bright and clean, atresia, its chemical mobility of the surface is low, so have excellent corrosion resisting performance.
Embodiment: make nickel foam
Electrotyping process treatment soln prescription:
Single nickel salt 450ml/l, nickelous chloride 150ml/l, boric acid 170ml/l, sodium-chlor 150ml/l, 1.4 butine 25ml/l, sodium lauryl sulphate 15ml/l, sulfuric acid 40ml/l.
Electrotyping process technology:
Solution temperature T=40 ℃ of current density D
K=3A/dm
2
Time t=6h
Calcination sintering process: 750 ℃ of temperature, time 1h.
Claims (4)
1, a kind of making method of foamed metal is characterized in that making of electrochemical method.
2, according to right 1, it is characterized in that adopting urethane foam is skeleton.
3, according to right 1, it is characterized in that the electrotyping process treatment process in the electrochemistry, that is: electrotyping process solution temperature T=10～90 ℃, current density D
K=1～40A/dm
2, treatment time t=0.5-12h, the working electrode area is 1: 2～4 with supporting electrode area ratio.
4, according to right 1, it is characterized in that the calcination sintering process behind the electrotyping process treatment process, that is: temperature T=500～1200 ℃, time t=0.5～2h, furnace atmosphere: H
