Hard nanostructured protective coatings, HNPC, provide enhanced tribological properties related to their high hardness, high wear-, scratch-, abrasion- and erosion-resistance, and low sliding wear, frequently combined with other functional characteristics such as corrosion resistance, high temperature stability, controlled thermal conductivity, biocompatibility, antifouling behaviour, and others. They are essential part of a wide range of application areas including aerospace, automobile, manufacturing, biomedical, forestry, energy control and others, and they represent a significant economic, environmental and energy impact worldwide. However, the application of HNPCs is often limited due to high stresses in the coatings. Understanding the origins of stress and controlling the stress level is of key importance for the performance and reliability of thin film and coating systems in various applications.***The proposed research program of the present Discovery Grant, application aims at performing cutting-edge studies using a holistic approach, namely to control the stress evolution in hard protective coatings by selectively adjusting the energetics of plasma-surface interactions during the film growth by pulse management in low pressure plasma based techniques PVD and PECVD deposition methods. This will then allow one to implement the stress characteristics, in smart and predictive way in the design of HNPC systems giving rise to their significantly improved tribomechanical performance the HNPC acceptance, and thus contribute to sustainable development.*****

硬质纳米结构保护涂层 (HNPC) 具有高硬度、高耐磨性、耐刮擦性、耐磨性和耐侵蚀性以及低滑动磨损等增强的摩擦学性能，通常与其他功能特性相结合，例如耐腐蚀、高温稳定性、受控导热性、生物相容性、防污行为等。它们是航空航天、汽车、制造、生物医学、林业、能源控制等广泛应用领域的重要组成部分，对全球经济、环境和能源产生了重大影响。然而，由于涂层中的高应力，HNPC 的应用往往受到限制。了解应力来源和控制应力水平对于各种应用中薄膜和涂层系统的性能和可靠性至关重要。***目前发现资助申请的拟议研究计划旨在使用整体方法进行尖端研究，即通过低压等离子体PVD技术中的脉冲管理选择性地调整薄膜生长过程中等离子体-表面相互作用的能量来控制硬质保护涂层中的应力演变 和PECVD沉积方法。这将使人们能够在 HNPC 系统的设计中以智能和预测的方式实现应力特征，从而显着提高 HNPC 认可的摩擦力学性能，从而为可持续发展做出贡献。 *****
