摘要

本文致力于研究铁基金属材料钝化的可能性。介绍了用重复脉冲和连续波1.064µm Nd:YAG激光器对碳钢模型样品进行激光处理的实验结果。研究表明,激光处理可以在钢表面形成62–77微米厚的致密保护膜。这些薄膜增强了金属的防腐性能。暴露于激光辐射可降低表面粗糙度(从Ra=0.53µm降至Ra=0.38µm)。这两种激光产生模式的激光辐射功率密度分别为10.2×105W/cm2和10.7×105W/cm,对应于钢处理的最佳(就耐腐蚀程度而言)模式。所进行的研究表明,Nd:YAG激光器的应用是一种很有前途的钢和铸铁艺术品表面钝化方法。所提出的铁防腐保护方法最有前途的应用之一是对铁基历史遗迹的表面进行钝化。

Laser Treatment as a New Approach to the Passivation of Iron-Based Historical Monuments
This article is devoted to the study of the possibility of the passivation of iron-based metallic materials. The experimental results obtained for the laser treatment of carbon steel model samples by the radiation of repetitively pulsed and continuous-wave 1.064 µm Nd:YAG lasers are described. It is shown that the laser treatment allows the formation of dense protection films, 62–77 microns thick, on the steel surface. The films enhance the anticorrosion properties of the metal. Exposure to laser radiation reduces the surface roughness (from Ra = 0.53 µm to Ra = 0.38 µm). Laser radiation power densities of 10.2 × 105 W/cm2 and 10.7 × 105 W/cm2 for these two laser generating modes, respectively, correspond to the optimum (in terms of the degree of corrosion resistance) modes of steel treatment. The conducted studies show that the application of Nd: YAG lasers is a promising method for the surface passivation of artworks created from steel and cast iron. One of the most promising applications of the proposed method for the anticorrosion protection of iron is the passivation of the surface of iron-based historical monuments.
