Calibration of a portable coercivity measurement instrument for assessing low-carbon steel

我们的公司位于曼彻斯特，专门开发电磁无损检测（NDT）产品。在过去的几年里，我们成功开发了一种新型的磁致伸缩仪，它具有便携性、快速测量速度和对样品制备的最小要求或零要求-这是现场非破坏性应用的独特优势。该系统已经商业化，发布给客户，并部署在外地。我们在不同的行业中发现了不同的应用，并不断增加我们的技术经验和客户参与度。例如，客户反馈证实，使用我们的新产品后，热处理评估效率大幅提高。过去需要5至6名工程师和20分钟的过程现在减少到2名工程师和2分钟。其他应用包括钢结构和电缆的老化和疲劳检测，残余应力分布和成品测试。与NPL一起，设计了实验测量装置，为MAIERIC的参考样品创建可追溯链。NPL将比较MAIERIC参比标准品和标准几何体上测定的结晶度值。软磁材料的直流磁特性通常使用磁导法（在BSI/IEC 60404-4中概述）确定。当前的测量标准通常限于明确定义的几何形状。为了直接比较，NPL将修改和现有的设置，以适应MAIERIC更小，非标准的几何形状。我们的目标行业包括电力，交通和开发，海洋，航空航天，冶金，化工和采矿，主要应用于评估钢结构，关键部件，机械等的工作寿命，老化和疲劳。成品的质量，金属的分选，在广泛的意义上，评估钢材在其整个使用寿命。能够为每个应用提供可追溯的测量结果意味着我们可以快速扩展市场。我们相信，解决我们目前的校准和可追溯性问题将为MAIERIC带来可观的额外收入。除了增加销售收入外，还可以提高我们和客户的流程效率以节省成本，从而实现重大的财务收益，并为曼彻斯特社区的技术和创新生态系统做出贡献。

Our company, located in Manchester, specialises in developing electromagnetic non-destructive testing (NDT) products. In the last couple of years, we have successfully developed a novel coercivity meter, which features portability, fast measurement speed and minimal or null requirements for sample preparation - unique advantages for on-site non-destructive applications. The system has been commercialised, released to clients, and deployed in the field. We have found diverse applications across different industries and have been continuously growing our technical experience and customer engagement. As an example, client's feedback confirms large efficiency improvement on heat-treatment assessment after using our novel product. A process that used to require 5 to 6 staff engineers and 20 minutes is now reduced to 2 engineers and 2 minutes. Other applications include aging and fatigue detection of steel structures and cables, residual stress distribution and testing of finished products.Together with NPL, an experimental measurement setup has been devised to create a traceability chain for MAIERIC's reference samples. NPL will compare coercivity values determined on MAIERIC's reference standards to those determined on standard geometries. The DC magnetic properties of soft magnetic materials are typically determined using the permeameter method (outlined in BSI/IEC 60404-4). Current measurement standards are generally limited to well defined geometry. For a direct comparison NPL will modify and existing set-up to accommodate MAIERIC's smaller, non-standard geometries.Our target industries include power, traffic and developments, marine, aerospace, metallurgy, chemical and mining, with main applications on assessing working life, aging and fatigue of steel structures, critical components, machinery, etc., quality of finished products, metal sorting, in a wide sense, assessment of steel during all its service life. To be able to produce traceable measurements for each application means we can expand our market quickly. We are confident that solving our current issues of calibration and traceability will bring to MAIERIC substantial additional revenue. As well as increasing sales revenue, improve process efficiency for both us and clients to save costs -- hence realising significant financial gains and contributing to the technology and innovation ecosystem of the Manchester community.
