Background:LSN Diffusion is a manufacturer of a gas and water atomised alloy powders. Formed in 2012, LSN Diffusion is based in South Wales and supplies products to the UK and for export to Europe, USA and Asia. It's product range covers international standard alloy powders and bespoke alloy powders for niche applications across a range of sectors. LSN combines is considerable experience of powder atomisation with its suite of purposed designed and constructed atomizing systems to adapt and meet a customer's often unique chemical and particulate requirements. LSN Diffusion holds a range of international certifications including accreditation to BS EN ISO 9001:2015, BS EN ISO 14001:2015 and Rolls Royce SABRe and GS3001. As LSN Diffusion enters its second decade of operations, potential development opportunities have been recognised in a number of key areas, including automotive, additive manufacturing and energy sectors. Advancement in these fields will require LSN Diffusion to enhance its R&D investment and profile.Project Description:The European Commission upcoming Euro 7 emissions standards legislate to ensure that emissions standards for vehicles are extended beyond exhaust emissions and will therefore set limits to particulate emissions from components such as brakes discs. It should be noted that this will apply to all vehicles including electric vehicles and thus will endure beyond the lifetime of current petrol/diesel designs.Against this background, the proposed project will investigate the development of environmentally-friendly powder alloy coatings for brake disc components and their application by high efficiency laser techniques. This has the wide-ranging potential to reduce particulate emissions from brake components in line with Euro 7 legislation. Project Components:- An initial review of the current legislation and technical advances combined with engagement with LSN's industrial partners will identify the potential alloy systems required to deliver a low particulate brake wear solution.- To meet the required coating/component performance, alloy systems will be developed, and subsequent powder batches produced using small-scale laboratory atomisation, followed by scaling to full-scale close-coupled gas/water atomisation in LSN's facility.- Once potential powder alloys have been identified and produced, brake component will be fabricated either as a laser-deposited coating onto an existing brake substrate and/or as a high-build additive layer component of a bespoke design.- Once a successful process/design has been delivered, wear performance of the coating in terms of component life and particulate emission will be assessed using laboratory-based techniques to quantify and rank coating performance.

背景：LSN扩散是一个气体和水雾化合金粉末的制造商。成立于2012年，LSN扩散总部设在南威尔士州，向英国供应产品，并出口到欧洲，美国和亚洲。其产品范围涵盖国际标准合金粉末和定制合金粉末，适用于一系列行业的利基应用。LSN将粉末雾化的丰富经验与其专门设计和建造的雾化系统套件相结合，以适应和满足客户通常独特的化学和颗粒要求。LSN Diffusion拥有一系列国际认证，包括BS EN ISO 9001：2015、BS EN ISO 14001：2015和劳斯莱斯SABRe和GS 3001认证。随着LSN Diffusion进入其运营的第二个十年，在汽车、增材制造和能源等多个关键领域，潜在的发展机会已经得到认可。这些领域的进步将需要LSN Diffusion加强其研发投资和形象。项目描述：欧盟委员会即将推出的欧7排放标准立法，以确保车辆的排放标准扩展到废气排放之外，因此将对制动盘等部件的颗粒排放设定限制。值得注意的是，这将适用于所有车辆，包括电动汽车，因此将超过目前的汽油/柴油设计的寿命。在此背景下，拟议项目将研究开发环保粉末合金涂层用于制动盘部件，并通过高效激光技术将其应用。这具有广泛的潜力，可以减少制动部件的颗粒排放，符合欧7法规。项目组成部分：-对当前立法和技术进步的初步审查，以及与LSN工业合作伙伴的合作，将确定提供低颗粒制动器磨损解决方案所需的潜在合金系统。为了满足所需的涂层/部件性能，将开发合金系统，并使用小规模实验室雾化生产后续粉末批次，然后在LSN的设施中扩展到全尺寸的紧密耦合气体/水雾化。一旦确定并生产出潜在的粉末合金，制动部件将作为激光沉积涂层制造到现有的制动基材上和/或作为定制设计的高成型增材层部件。一旦交付成功的工艺/设计，将使用基于实验室的技术评估涂层在部件寿命和颗粒排放方面的磨损性能，以量化和排名涂层性能。
