摘要
派拉纶真空镀膜技术是目前最先进的文物保护技术之一,但对其在铁质文物保护方面的应用研究较少。为此,通过失重法、电化学极化曲线和电化学交流阻抗谱研究了pH值为5的H2SO4溶液中派拉纶镀膜对铁质文物模拟试样的保护作用。结果表明,派拉纶真空涂覆层主要通过抑制阴极的氧还原反应过程,起到保护效果。
The protection of iron relics in H2SO4 solu-tion with a pH value of 5 by vacuum plated paryiene coating was investigated using weight-loss test and measurements of potentiodymamic polarization curve and electrochemical impedance spectrum.It was found that vacuum plated parylene coating could protect the iron relics by retarding redox reaction at the cathode.
