项目摘要

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.

硬纳米结构的防护涂层HNPC提供了与高磨损，高磨损，刮擦，磨损和侵蚀性以及低滑动磨损相关的增强的摩擦学特性，并且经常与其他功能特性相结合，例如腐蚀性，高温稳定性，高温稳定性，高温导热性，受控性，生物可控性，生物适应性，生物适应性，抗抗原行为，以及其他。它们是广泛应用领域的重要组成部分，包括航空航天，汽车，制造业，生物医学，林业，能源控制等，它们代表了全球的重要经济，环境和能源影响。但是，由于涂料中的高应力，HNPC的应用通常受到限制。了解压力的起源和控制压力水平对于各种应用中的薄膜和涂料系统的性能和可靠性至关重要。本发现赠款的拟议研究计划旨在使用整体方法进行最先进的研究，即通过选择性地调整基于低压等离子体的基于低压等离子体的技术PVD和PECVD沉积方法，通过选择性地调整薄膜中等离子表面相互作用的能量来控制硬保护涂层的应力演化。然后，这将使人们在HNPC系统的设计中以智能和预测的方式实施压力特征，从而显着改善了HNPC的互动性能，从而有助于可持续发展。
