Factors affecting the catalytic activity such as crystal structure and surface oxygen property were examined by XRD and TPD MS techniques.

The surface oxidization behaviors of Ce-5La(at%) alloy in dry air at 200 ℃ was investigated.

This paper macrographically analyzed the surface oxidization and the thichness of oxidized layer of 4004 alloy which successively undergo different temperature and different holding time during 350～525 ℃ according to the hot rolling bolding processes of 4004/3003/4004.

Enrichment of Cu,Ni in surface oxidation layer of copper-bearing age-hardening steel was investigated.

In order to solve the problem that copper wire is oxidized easily,using the oxidation live-weight gain experiment,the surface oxidation of different structure and purity copper wires have been studied.

Based on the Griffith theory, this paper suggested that the compressive strength of diamond can be enhanced by means of surface oxidation.

The surface oxide film of plug should be symmetrical and compact.

The effect of RE-modification and Sr-modification on the surface oxide film of A356 aluminum alloy melt was investigated in this paper.

This is because the oxide film at the A356 melt surface was almost composed of SrO, but this oxide make the surface oxide film looser had been loosened and cracked owing to the enrichment of the Strontium of t.
