This project aims to develop an innovative deposition process to protect, manufacture and repair high-value parts in a more eco-responsible and sustainable manner. Applications will be found in the aerospace, surface transportation and biomedical sectors as well as in other industry sectors important for the Canadian economy and society.The innovative Liquid Accelerated Cold Spray (LACS) process uses water as a propellant liquid instead of a high volume of gas such as nitrogen or helium. The process involves forming a high-speed water jet in which we inject metallic powders that are accelerated at speeds higher than 0.5 km/s before impacting on the part to be coated or manufactured. Due to their high speed, the metallic particles are deformed upon impact and welded to the surface. Water being much denser than gases, it can accelerate particles more efficiently permitting a reduction of cost and usage of resources.Experts in surface engineering, fluid mechanics, modeling and process control are joining their forces to bring this technology to a higher level of maturity and take it closer to commercialization.

该项目旨在开发一种创新的沉积工艺，以更加环保和可持续的方式保护、制造和修复高价值零件。其应用将广泛应用于航空航天、地面运输和生物医学领域以及对加拿大经济和社会重要的其他工业领域。创新的液体加速冷喷涂 (LACS) 工艺使用水作为推进剂液体，而不是大量的液体推进剂。气体，例如氮气或氦气。该过程涉及形成高速水射流，其中我们喷射金属粉末，这些粉末在撞击要涂层或制造的零件之前以高于 0.5 公里/秒的速度加速。由于速度较高，金属颗粒在撞击时会变形并焊接到表面。水比气体密度大得多，它可以更有效地加速颗粒，从而降低成本和资源使用。表面工程、流体力学、建模和过程控制方面的专家正在联手使这项技术达到更高的成熟度和水平。使其更接近商业化。
