The rapid progress in science and technology requires a constant search for new coating materials and surface engineering processes that provide an ever increasing performance. Within this research program, the applicant proposes to perform cutting-edge studies on new, low pressure, high density pulsed plasma (HDPP) processes that will be used for the fabrication of structurally-controlled hard, new-generation protective coatings (NGPC) with tailored mechanical, elasto-plastic and thermal properties and enhanced wear-, erosion- and corrosion resistance and other characteristics suitable for different advanced applications including components of aircraft and helicopters, automobile engines, medical instruments and others. Specifically, the HDPP approach, and particularly its variants High Power Impulse Magnetron Sputtering (HIPIMS) and Pulsed Plasma-Enhanced Chemical Vapor Deposition (P-PECVD), is seen as a unique possibility of controlling the films' microstructural features on nanometer scale. This will allow one to selectively adjust the hardness and the Young's modulus of the materials, and hence obtain films with substantially enhanced toughness, tribological performance and other multifunctional properties. Such nanostructured (nanocomposite) films will be integrated in complex coating architectures that meet specific demanding application requirements, thus leading to a possibly significant technological and economic impact.

科学技术的快速发展要求不断寻找新的涂层材料和表面工程工艺，以提供不断提高的性能。 在这项研究计划中，申请人提出对新的低压高密度脉冲等离子体（HDPP）工艺进行尖端研究，该工艺将用于制造具有定制的机械、弹塑性和热性能以及增强的磨损的结构控制的硬的新一代保护涂层（NGPC）。耐腐蚀性和耐腐蚀性以及其他特性，适用于不同的先进应用，包括飞机和直升机、汽车发动机、医疗器械等的部件。 具体而言，HDPP方法，特别是其变体高功率脉冲磁控溅射（HIPIMS）和脉冲等离子体增强化学气相沉积（P-PECVD），被视为在纳米尺度上控制膜的微观结构特征的独特可能性。这将允许人们选择性地调节材料的硬度和杨氏模量，并因此获得具有显著增强的韧性、摩擦学性能和其他多功能性质的膜。这种纳米结构（纳米复合材料）薄膜将被整合到复杂的涂层结构中，以满足特定的苛刻应用要求，从而产生可能重大的技术和经济影响。
