Abstract
The present invention relates to an electrochemical polishing method for aluminum and aluminum alloy welding wires. In the method, polishing liquid takes phosphoric acid as the base and is added with corrosion inhibitors and activating agents. The method has the advantages of no toxicity, low temperature and easy regeneration. The indexes of welding wires processed by the method are consistent with the surface quality of welding wires of the USA, Canada, Italy, etc. and reach international standards; the welding wires can all keep equal light degree and can be directly used by factories; the method also obtains high quality welding seams for relieving originally established steps of degreasing, cleaning, etc. and special cleaning workshops in factories and is suitable for the requirements of high quality and high efficiency production.
Description
Method of the present invention belongs to the process of surface treatment of welding material.
China's aluminium welding wire tradition mode of supplly is with the welding wire oiling, and the coiled great circle is supplied with seizing backs such as sack sheets again.After using producer to buy back, carry out degreasing earlier, and set up specially between alkali cleaning acid neutral cleaning Vehicle and clean, must use up in 24 hours after the welding wire oven dry, otherwise must clean again, treatment step is numerous and diverse, expends a large amount of human and material resources.Along with being extensive use of of aluminium alloy device, aluminium alloy welding butt welding silk requires to improve, there is the loose oxide film of polynuclear plane in welding wire surface, be the principal element that influences weldquality, at present domestic have manufacturer that the chemical rightenning processing is carried out on the aluminium welding wire surface, though use producer can cancel between cleaning Vehicle, but still there is oxide film loose and that easily absorb water in welding wire surface after the chemical rightenning, quality guaranteed period is about three months, and the time, then the surface became lead if longer.USSR (Union of Soviet Socialist Republics) was reported the method for aluminium welding wire surface electrochemistry polishing, was base with phosphoric acid, added nitric acid as activator, and added inhibiter, but do not report concrete prescription and ratio (H.M.Bopo д a й A
BTOMA T и ц E CK A я,
CBA
PKA1978N.1,1980, N.9) U.S. also reported workpiece was carried out electropolishing, use hydrofluoric acid and chromic acid (Met.Filish 1983 N.8,1986, p397-405), this class electrolytic solution is highly toxic substance, very easily contaminate environment can not be used in a large number.
The object of the invention is to provide a kind of electrolytic solution that can use in a large number, with electrochemical polishing method aluminium and aluminium alloy welding wire are carried out surface treatment, improve homemade welding wire quality, and the convenient producer that uses, remove between its cleaning Vehicle, simplify handling procedure, thereby satisfy high quality and high efficiency production needs.
Aluminium of the present invention and aluminium alloy welding wire electrochemical polishing method, using with phosphoric acid is the polishing fluid of base, contains inhibiter and activator in the polishing fluid, various compositions account for total weight percent and are in the polishing fluid:
Phosphoric acid 30-60%
Sulfuric acid 5-20%
Ethylene glycol 20-40%
All the other are water;
Working temperature 60-100 ℃, polishing time 2-6 minute, current density 4-20A/dm
2
When various compositions in the polishing fluid account for total weight percent when following, better effects if:
Phosphatase 24 0-58%
Sulfuric acid 10-18%
Ethylene glycol 25-30%
All the other are water.
Use method of the present invention, nontoxic, temperature is low, regeneration easily.Ion deposition in the treating processes in the polishing fluid is at the welding wire recessed part, and the welding wire bossing is dissolved, so welding wire surface removed convex part, and surface smoothness is improved.The LF that handled through method of the present invention

21And the Al-Cu-Mg alloy welding wire compares with the U.S. 4340 welding wires, and every indexs such as the weightlessness when luminance brightness, welding wire surface hydrogen content, polishing, contact resistance are all consistent, reach international standards.The welding wire of handling all can keep equal bright degree in 3 years, and producer can directly use, and has simplified degreasing, every treatment process such as cleaning, and can remove between its special cleaning Vehicle, saved human and material resources and financial resources.
Concrete when implementing method of the present invention, use the proportioning of following two kinds of polishing fluids, all reach good effect:
1. phosphatase 24 0%, sulfuric acid 15%, ethylene glycol 28%, water 17%.
Polishing time 70-89 ℃.Polishing time 3-5 minute, current density 8-16A/dm

2. phosphoric acid 55%, sulfuric acid 14%, ethylene glycol 25%, water 6%.
Temperature, time, the current density handled are the same.
