Role of Hydrogen in Cavitation Degradation of Iron in Water Solutions Jarosław CHMIEL1,a*, Ellina ŁUNARSKA2,b 1Maritime University of Szczecin,1/2 Wały Chrobrego St. 70-500 Szczecin, Poland 2Institute of Physical Chemistry PAS, 44/52 Kasprzaka St., 01-224 Warsaw, Poland a j.chmiel@am.szczecin.pl, b elunarska@ichf.edu.pl Keywords: cavitation vibration amplitude, cathodic polarization, hydrogen permeation rate, stress Abstract Hydrogen ingress into a metal has been observed at cavitation in distilled water and in 3% NaCl solution at open circuit potential.
It should be noted that in the case of cathodic polarization applied in this study, no degradation of the iron structure was stated.

Development and prospect of Al scraps reproduction technology in china DeQin Sun (school of chemistry and materials Engineering, Changshu Institute of Technology, Changshu 215500,China) sundeqin@cslg.edu.cn Key words: Al scraps recycling; non-metallic inclusions; contaminating elements separation; solidification control Abstract: Al scraps reproduction was the need of sustainable development.
Therefore the controlling of solidification structure and casting process was important part of metal manufacturing process.
