Electro-spark deposition (ESD), a micro-welding process, is increasingly used to apply surface coatings for repair of damaged high value precision products or modify their surfaces for a abroad range of aerospace, defense, automobile, nuclear and medical applications. Huys Industries Limited, a leading company on resistance welding consumables headquarted in Ontario, Canada has developed expertise over a few decades in the use of ESD coating to improve electrode tip life in resistance spot welding (RSW) of Zn-coated automotive steel sheets. Based on many years' collaborations with the University of Waterloo, Huys has recently developed new ESD technologies (ESD machines and coating materials) to improve RSW electrode tip life. This research is to further develop Huys' patented and patent-pending ESD applicators and power supplies and expand their applications on other coating/workpiece combinations. Specifically, the objectives of this research are to (1) Improve the design of Huys' ESD machines (including power supplies and applicators) based on studying the effects of electrical and applicator parameters on coating characteristics and performance; (2) Improve RSW electrode tip life with TiB2 coating based on studying and understanding of relationships between process parameters, coating characteristics and electrode tip life; and (3) Expand Huys' ESD technologies into others application areas (i.e., new coating and workpiece combinations) based on studying relationships between process parameters, coating characteristics and performance. The knowledge developed through this work has the potential to improve productivity and quality of manufactured products in many industrial sectors. This work also aims to train 3 graduate students, one undergraduate co-op student, one post-doctoral fellow and one research engineer each year and these highly-qualified personnel (HQP) are badly needed by the Ontario and Canada manufacturing sectors.

电火花沉积 (ESD) 是一种微焊接工艺，越来越多地用于应用表面涂层来修复受损的高价值精密产品或修改其表面，以用于广泛的航空航天、国防、汽车、核和医疗应用。 Huys Industries Limited 是一家领先的电阻焊耗材公司，总部位于加拿大安大略省，数十年来在使用 ESD 涂层来提高镀锌汽车钢板电阻点焊 (RSW) 电极尖端寿命方面积累了丰富的专业知识。基于与滑铁卢大学多年的合作，Huys 最近开发了新的 ESD 技术（ESD 机器和涂层材料），以提高 RSW 电极尖端的寿命。 这项研究旨在进一步开发 Huys 的专利和正在申请专利的 ESD 涂抹器和电源，并将其应用扩展到其他涂层/工件组合。具体来说，本研究的目标是（1）基于研究电气和涂抹器参数对涂层特性和性能的影响，改进Huys的ESD机器（包括电源和涂抹器）的设计； (2) 基于对工艺参数、涂层特性和电极头寿命之间关系的研究和理解，利用 TiB2 涂层提高 RSW 电极头寿命； (3) 基于研究工艺参数、涂层特性和性能之间的关系，将 Huys 的 ESD 技术扩展到其他应用领域（即新涂层和工件组合）。 通过这项工作开发的知识有可能提高许多工业部门的生产率和制成品的质量。这项工作还旨在每年培养3名研究生、1名本科生、1名博士后和1名研究工程师，这些高素质人才（HQP）是安大略省和加拿大制造业急需的。
