Abstract The removal of old repairs made using metal flake paint, commonly referred to as bronze paint, has often been difficult to achieve from gilded wood and especially from oil gilded surfaces with similar solubility parameters. Conservators at the National Trust's Knole Conservation Studio in the UK treated gilded picture frames from the Knole House collection using an energy-attenuated Fotona (Dualis XS) Erbium:YAG laser, with fluencies between 0.5 and 1.0J/cm2, pre-wetted with hydroxyl and non-hydroxyl group-containing solvents. Comparisons of the effects of cleaning using only solvents and with the laser were made, and cross-sectional and media composition analysis carried out using optical microscopy, scanning electron microscopy with energy dispersive X-ray (SEM-EDX), Raman and Fourier transform infrared (FTIR) spectroscopies.

使用Erbium：YAG激光去除镀金相框上的古铜色油漆修补物

摘要用金属片状漆（通常称为古铜色漆）进行的旧修复通常很难从镀金的木材，尤其是具有相似溶解度参数的油性镀金表面上实现。英国国家信托基金会（National Trust's Knole Conservation Studio）的保管人使用能量衰减的Fotona（Dualis XS）:: YAG激光处理了Knole House系列的镀金相框，其通量在0.5至1.0J / cm2之间，并预先用羟基润湿和不含羟基的溶剂。比较仅使用溶剂和激光清洁的效果，并使用光学显微镜，扫描电子显微镜，能量色散X射线（SEM-EDX），拉曼光谱和傅立叶变换红外光谱进行横截面和介质成分分析（FTIR）光谱学。
