The effect of plastic deformation on the solution and escape of hydrogen in low-carbon steel has been investigated by using electrolysis-cathode-hydrogenating method the solution hydrogen can not larger the solution diffusivity and the smaller the escape diffuivity .

The relationship between solid solution Mg segregated on grain boundary and the content of Hpermeation in 7175 aluninium alloy under various aging conditions was studied by means of energy spectra, ion mass microprobe analysis and cathodic Hpermeation.

Effect of cathodic hydrogen charging on the ductility of steel 1Cr18Ni9Ti was investigated by means of repeated bend test.

Cerium-rich conversion coatings were deposited on porous film of anodized auminoum by cathodic electrolysis in a solution containing 1 g/L CeCl 3·7H 2O and 10 ml/L H 2O 2.

Electrochemical measurements, corrosion tests, SEM and EDAX were used to investigate forming cerium conversion coatings on aluminum alloys in cerium salt solutions by cathodic electrolysis.
