摘　　要：在自制Cu-Sn-Pb合金表面上进行盐酸腐蚀,用红外反射及红外-光声光谱方法监测粉状锈(Cu_2(OH)_3Cl)的生长过程。结果发现,在酸性环境中Cu_2(OH)_3Cl生长迅速;二价铜锈的生成需通过一价铜锈(CuCl)这一中间产物;粉状锈有传染性,可通过空气由锈蚀样品传至无锈样品,锈体颗粒对光线的散射作用强,结合热力学计算对青铜生锈机理进行了探索。The surface of self-made Cu-Sn-Pb alloy was corroded by HCl, and the process of corrosion was detected by the methods of IR-reflection and IR-photoacoustic spectra in situ. It was found that the powder rust-eaten product (Cu2(OH)3Cl) develops fast; the bronze corrosion forms via the intermediate CuCl; the powder state corrosion (PSC) was infectious; and that the particle of PSC scattered light seriously. The results above is discussed and the mechanism of PSC-formation is searched with the thermodynamical calculations.
