Arolled mild steel wascoated byconductive polymers( polyaniline/ MMPand polyaniline/HCSA) andthenim mersedin hot water(50 ℃) fordifferenttimesforstudytheadhesion ofcoatings.It wasfound thatthe adhesion tendsto decrease over time. Thestudyshown that onebrittle and porous Fe3 O4 layer formed between conductive polymercoating and steelsub stratein a moistenvironmentand, asa result, decreased thecoating adhesions.

Bi2Sr2CaCu2Ox superconductor was studied by differential scanning calorimetry (DSC) and thermogravimetry (TG) in different atmospheres. It is discovered that there is a thermal anomaly in the DSC curve, associated with a weight loss in the TG curve before the melting of the sample. Careful thermal analysis and high temperature X-ray diffraction reveal that the thermal anomaly and the weight loss show an instability of the crystalline Iattice. By annealing the sample in oxygen and argon, respectively and then by TC measurement and thermal analysis, the coincidence of transition temperature with the instability is found. The coincidence is further confirmed by Y-doped 2212 phase.

研究了粉末渗锌涂层钢在3.5％NaCl溶液、人工海水(ASW)和天然海水(NSW)中的腐蚀行为.结果表明,渗锌层主要成分为Zn-Fe合金.渗锌涂层在3.5％NaCl溶液中的腐蚀速率要大于ASW和NSW.这可能是由于两种介质中含有的成分能够与Zn反应,生成更难溶的物质堆积于涂层表面,导致腐蚀速率降低.
