MDS Coating Technologies (MCT) is looking for erosion-corrosion resistant surface protective solutions forindustrial gas turbine engines that are both cost effective (equipment cost, cost of ownership, throughput) andallow mechanical properties' control and stress control of the coatings to maximize application performance.MCT's current vacuum arc plasma film technology works on the principle of physical vapor deposition (PVD)methodology to deposit up to 50-micron thick film. The process is prohibitively slow, costing the companyturnaround time to service established customers, and increasingly depressing its business vision to grow in thegeothermal and renewable energy market. Challenging enough, components deployed in these burgeoningapplications require surface protective layers developed on heat sensitive substrates and vacuum-incompatibleshapes. The goal of this NSERC Engage project is to develop and evaluate the high-temperature (>500-deg C)fluid erosion and fatigue properties of a novel nanostructured coating by spraying ceramic-metallicnanocrystalline composite Al2O3-Ni(Cr) particle feedstock developed in Dr. Saha's Nanocomposites andMechanics (NCM) Lab at UNB. Feedstock spray work will be accomplished using a low thermal energytechnology, high pressure cold spray (HPCS), at the National Research Council's thermal spray lab atBoucherville (QC). The coating test and characterization work will be conducted jointly in NCM Lab andMCT's in-house lab in Montreal, QC. The obtained results, assessed against desired objectives, will take thisindustrial collaboration into three distinct and integrative levels: (1) determine the coating technology readinesslevel (TRL), expected to fall between 4 and 6, by implementing results into field trials, (2) amass resources toown an HPCS infrastructure at MCT's PEI Manufacturing site, and (3) embark on a 5-year CRD project tobring the technology to customer service readiness following rigorous research and development curriculum.This Engage project is a first-hand example of how an industrial collaboration can unfold by bringingacademic, company, and government research and innovation strengths under one umbrella.

MDS Coating Technologies（MCT）正在为工业燃气涡轮机发动机寻找既具有成本效益又具有耐腐蚀性的表面保护解决方案（设备成本、拥有成本、MCT目前的真空电弧等离子体薄膜技术基于物理气相沉积（PVD）方法的原理，可存款高达50- 60%的薄膜，微米厚的薄膜。这个过程非常缓慢，花费了公司为老客户服务的周转时间，并且越来越抑制了其在地热和可再生能源市场增长的商业愿景。这些新兴应用中部署的组件需要在热敏基底和真空不兼容的形状上开发表面保护层。该NSERC Engage项目的目标是开发和评估一种新型纳米结构涂层的高温（>500摄氏度）流体侵蚀和疲劳性能，该涂层通过喷涂在UNB Saha博士的纳米复合材料和力学（NCM）实验室开发的陶瓷-金属纳米晶复合材料Al 2 O3-Ni（Cr）颗粒原料。原料喷涂工作将在位于Boucherville（QC）的国家研究理事会热喷涂实验室使用低热能技术高压冷喷涂（HPCS）完成。涂层测试和表征工作将在NCM实验室和MCT位于QC蒙特利尔的内部实验室联合进行。根据预期目标评估所获得的结果，将把这种工业合作分为三个不同的综合层次：（1）通过将结果实施到现场试验中来确定涂层技术准备水平（TRL），预期其落在4和6之间，（2）积聚资源以在MCT的PEI制造场所拥有HPCS基础设施，以及（3）着手一项为期5年的CRD项目，在严格的研究和开发课程之后，将该技术带入客户服务准备阶段。该Engage项目是如何通过将学术界、公司和政府的研究和创新优势置于一个保护伞下来展开工业合作的第一手例子。
