Abstract

Modern artworks are constructed using a variety of materials and techniques. Sculptures, which predominantly consist of metals, usually have different shapes and consist of different material mixtures. The structural and material properties of these sculptures are often controlled by conservation treatment methods. However, the application of existing treatment methods is challenging at times, indicating that more diverse treatment materials and techniques are necessary. Therefore, in this study, a treatment method that employs volatile corrosion inhibitor(VCI) powder, rather than an anti-corrosion solution, for the conservation and management of metal artworks was used. VCI powder and VCI films containing VCI powder were used, and the results obtained confirmed that both of them showed anti-corrosion effect. Only a slight change in the chromaticity of metal samples was observed, and compared to the untreated samples, the application of the VCI powder resulted in a decrease in the rate of corrosion by half. Moreover, VCI film tests revealed that comparing to the untreated or polyethylene film-treated samples, VCI film treatment resulted in a decrease in the occurrence of corrosion compounds. The contact angle, surface energy, and surface electrical resistance were measured, and the evaluation of these surface properties established the anti-corrosion effect of VCI. Additionally, direct application of VCI and VCI films on actual sculptures further confirmed the anti-corrosion effect of VCI.

현대 미술작품은 재료와 제작기법, 종류가 매우 다양하게 사용되고 있으며 특히 조각작품 중 많은 비율을 차지하는 금속의 경우 형태가 다양하고 여러 재질과 혼합된 작품이 다수 존재한다. 이러한 구조적, 재료적 특성은 보존처리 시 기존의 처리 방법을 적용하기 어려운 경우가 많아 보다 다양한 처리 재료 및 방법이 요구된다. 본 연구에서는 금속 작품의 효과적인 보존처리를 위해 방청제(Rust inhibitor, 防錆劑)를 작품에 직접적으로 도포하는 방법이 아닌 기화성 방청제를 적용하였으며, 기화성 방청제 및 이를 함유한 방청필름의 방청효과를 평가하였다. 금속 시편을 대상으로 기화성 방청제를 적용한 방청처리 결과, 시편의 색도 변화는 미미하였으며, 부식 속도는 방청 미처리 시편과 비교하였을 때 절반 정도 감소하는 것을 확인하였다. 방청필름 적용 실험 결과, 방청필름 사용 시 미처리 및 폴리에틸렌 필름을 사용한 시편보다 부식화합물의 발생이 감소하였다. 접촉각 및 표면에너지, 표면전기저항 측정을 통해 표면의 물성을 측정하였으며 방청피막이 형성됨을 확인하였다. 또한 기화성 방청제 및 방청필름을 실제 조각작품에 적용하여 방청효과를 확인하였다.
