English Heritage CDA In Conservation Of Late 19th And 20th Century Artillery Pieces.

背景英国遗产(EH)收藏了400多门来自许多时代的大炮、马车和枪支，涉及29个历史遗迹，包括多佛城堡、潘登尼斯和蒂尔伯里堡。它们的功能意味着火炮通常位于包括沿海半岛和港口在内的裸露地点，使它们受到一系列环境条件的影响，包括暴露在空气中的盐分和污染，这会加速腐蚀，增加补救保护的必要性。更现代的火炮设计的复杂性涉及更广泛的材料和部件，这些材料和部件充当水陷阱，这增加了它们对腐蚀的脆弱性。制定基于证据的长期收藏保护策略是保护这些遗产资产并优先保护它们的当务之急。项目目标和方法关键研究问题是：英国遗产收藏中的现代火炮最有效的管理策略是什么？要回答这个问题，该项目将问：在EH庄园中发现火炮的历史背景是什么？哪些火炮显示出最严重的腐蚀？这与室外展示环境特定的因素有何关系？涂层对保护火炮免受腐蚀的相对有效性是什么？历史研究建立EH收藏中19世纪末和20世纪火炮的历史背景和遗址特性，将地点和收藏品联系起来，提供对英格兰历史的独特视角。EH已经在对每一把枪的历史和意义以及它们的位置特殊性进行研究，这将为治疗的优先顺序提供信息。学生将对此进行研究，以了解特定火炮的位置和历史使用之间的关系，使它们能够将条件和地点联系起来。条件和腐蚀对火炮部件的科学调查将评估部件的组成和条件，确定那些显示出最严重腐蚀迹象的部件，并将这些与最初的来源研究联系起来。文献综述和使用便携式光谱分析的现场分析将确定与火炮生产和腐蚀过程发生有关的合金成分。涂层的有效性该项目将重点了解在适当的环境下对火炮进行保护处理的有效性，集中评估当前涂层系统的性能，并研究氟聚合物等新型替代品。该项目的持续时间提供了将人工老化与现场实时降解研究相结合的机会。

BackgroundEnglish Heritage (EH) cares for over 400 cannons, carriages and guns from many eras, across 29 historic sites including Dover Castle, Pendennis, and Tilbury Fort. Their function means artillery are often situated in exposed sites that include coastal peninsulas and ports, subjecting them to a range of environmental conditions that include exposure to airborne salts and pollution, which accelerates corrosion and increases the need for remedial conservation.The complexity of more modern artillery designs involves a wider range of materials and components that act as water traps, which increases their vulnerability to corrosion. Developing evidence based long term collections care strategies is imperative to protect these heritage assets and to prioritise their conservation.Project aims and methodsThe key research question is:What is the most effective management strategy for modern artillery in the English Heritage collection?To answer this, the project will ask:What is the historical context in which artillery is found across the EH estate?Which artillery pieces display the greatest corrosion and how does this relate to factors specific to outdoor display environments?What is the relative effectiveness of coatings to protect artillery from corrosion?Historical studyEstablishing historic context and site specificity of late 19th and 20th Century artillery within the EH collection will connect locations and collections to provide a unique perspective on England's history. EH has already been conducting work on the history and significance of each gun and their site specificity which will inform prioritisation of treatment. The student will examine this to develop an understanding of relationships between location and historic use of specific artillery, allowing them to correlate condition and site.Condition and corrosionScientific investigation of the artillery pieces will assess the composition and condition of components, identifying those parts that show the greatest signs of corrosion and linking these to the initial research into provenance. Literature review and in-situ analysis using portable spectroscopy will determine alloy composition, which will be related to artillery production and corrosion processes occurring.Effectiveness of coatingsThe project will then focus on understanding the effectiveness of conservation treatments for artillery within their appropriate contexts, concentrating on assessing performance of current coating systems and investigating novel alternatives such as fluoropolymers. The duration of this project offers the opportunity to couple artificial ageing with real-time degradation studies onsite.
