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

背景英国遗产（EH）关心超过400大炮，马车和枪支从许多时代，在29个历史遗址，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暴露地点，使它们受到一系列环境条件的影响，包括暴露于空气中的盐和污染，这加速了腐蚀并增加了补救保护的必要性。更现代的火炮设计的复杂性涉及更广泛的材料和组件，这些材料和组件充当水陷阱，这增加了它们对腐蚀的脆弱性。发展基于证据的长期收藏护理战略是当务之急，以保护这些遗产资产，并优先考虑其conservation.Project的目标和methodsThe关键的研究问题是：什么是最有效的管理策略，现代火炮在英国的遗产收藏？为了回答这个问题，该项目将问：在EH庄园发现火炮的历史背景是什么？哪些火炮显示最大的腐蚀，这是如何与特定的户外显示环境的因素？涂层保护火炮免受腐蚀的相对有效性是多少？历史研究在EH系列中建立19世纪末和20世纪世纪火炮的历史背景和场地特异性将连接地点和收藏品，以提供对英格兰历史的独特视角。EH已经在研究每支枪的历史和意义以及它们的部位特异性，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，使他们能够将条件和地点联系起来。条件和腐蚀对火炮的科学调查将评估部件的组成和条件，确定那些显示出最大腐蚀迹象的部件，并将其与最初的来源研究联系起来。文献回顾和现场分析使用便携式光谱将确定合金成分，这将是相关的火炮生产和腐蚀过程发生。有效性coatingsThe项目将专注于了解保护治疗的有效性，为火炮在其适当的情况下，集中在评估当前的涂层系统的性能和调查新的替代品，如氟聚合物。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.
