The Influence of Corrosion Inhibitor BTA on Zinc Flux Yuan-yuan XU 1,a, Yan-fu YAN 1,b, Yang-yang SHENG 1,c, Hong-na WANG 1,d 1College of Material Science and Engineering, He nan University of Science and Technology, Luoyang，China 471003 aemail: xyy19880906@sina.cn ,bemail: yanyanfu@mail.haust.edu.cn,cemail: jiuyongtao@163.com, demail: xiaona1986107@126.com Key words: corrosion inhibitor; Flux; Zn20Sn; Solder; wettability Abstract.
To join different content of the active material in the flux could also improve its corrosion resistance of substrate and wetting effects.
Flux was the key link in modern electronic industry material, flux of the addition of active material would make copper corrosion, there were so many ways to solve the problem of copper corrosion, in metallurgy, adding other metals in copper could improve corrosion resistance of alloy, such as, adding 0.7 wt. % of the tin in copper could significantly improve the corrosion resistant ability, in a variety of methods, adding the corrosion inhibitor in the flux was the most practical [3-4].

Increasing the Quality of Welded Joints of Al-Si 6082 Alloys by Introducing Forced Vibrations BODEANU Mihai Alexandru1,a* and MACHEDON PISU Teodor1,b 1Transilvania University of Brasov, Faculty of Materials Science and Engineering, Materials Engineering and Welding Department, 29 Eroilor Blvd., 500036, Brasov, Romania abodeanum88@yahoo.com, btmache@unitbv.ro Keywords: forced vibrations, aluminum alloys, welding technology Abstract.
There are many papers that highlight the positive role of vibrations in materials solidification and welding, refining the structure, increasing the mechanical properties and decreasing the internal stresses [2, 3].
Materials and Methods To perform the experimental tests were used samples of aluminum alloy 6082 (AlSi1MgMn) and as filler Al 4043 (AlSi5) alloy wire.
Vickers HV0.1 micro-hardness in the weld and in the thermal influenced area Al 6082 Alloy Micro-Macro Structure For microstructure analysis of the welded alloy was used the OMNIMET- BUEHLER equipped with a microscope whose resolution goes up to 1000x and one analysis program for ferrous and nonferrous materials.

Iron and steel materials with outstanding alkaline corrosion resistance are strongly demanded for their fabrication equipments.
Interoduction Chromium cast steel and iron are widely used as corrosion-resistant materials in acid, neutral, and diluted alkaline solution.
Anode dissolving corrosion was reported to occur for iron and steel materials in the hot concentrated alkaline at temperature of above 80* [1].

It is harder for molten materials in discharge gap to be expelled.
Fewer materials are in the molten state, and fewer materials are splattered onto the surface of tool electrode.
More molten materials stay in the area near the surface of tool electrode.
And compensation of removed materials is accomplished.
