Abstract For over a decade, hard coatings have been providing wear resistance to cutting tools materials. The industrial prerequisites and advancements in hard coatings provide drastic improvements with respect to productivity and component lifetimes and hence reduce cost. However, selection of a desirable coating is often not straight forward, in view of the fact that the number of hard coating materials and their combinations are constantly increasing. The nano-composite coating materials are utilized, in order to have superior control over properties such as high chemical stability, wear resistance, and temperature of the coatings. This article discussed the development and application of an electrostatic spray coating process (ESC). This novel process exploits the creation of nano-composite coatings on cutting tool material, resulting in uniform thickness, high quality, and durability, with the intention to enhance the resistance to wear. The composition of ternary components in the deposited coating varies by weight percentage in five different compositions of YSZ1–x–y, TiNx, SiNy. Mechanical and tribological properties of nano-composite coatings are investigated. Scanning electron microscopy (SEM) was used to study the microstructure and wear morphology, in addition to energy-dispersive X-ray analysis (EDAX) and elemental mapping. With the aim to understand the interaction among wear behavior and coating properties, the mechanical tests including micro-hardness at ambient and elevated temperature were conducted. Scratch tests were performed to evaluate adhesive failure and critical load of coatings at room temperature. A tribometer was utilized to conduct dry sliding wear tests between a tungsten carbide pin coated with nano-composite and a Ti-6Al-4V disc. The ternary nanocomposite coating exhibited superior tribological properties compared to single and binary coatings. The composition that provides favorable results in relation to mechanical and tribological properties is preferred for coating the substrate to enhance the performance of the substrate in various industrial applications.

摘要 十多年来，硬质涂层一直为切削刀具材料提供耐磨性。硬涂层的工业先决条件和进步极大地提高了生产率和部件寿命，从而降低了成本。然而，考虑到硬涂层材料及其组合的数量不断增加，选择理想的涂层通常不是一蹴而就的。使用纳米复合涂层材料，以便对涂层的高化学稳定性、耐磨性和温度等性能进行出色的控制。本文讨论了静电喷涂工艺 (ESC) 的开发和应用。这种新颖的工艺利用在切削刀具材料上形成纳米复合涂层，从而实现均匀的厚度、高质量和耐用性，旨在增强耐磨性。沉积涂层中三元组分的组成在 YSZ1-x-y、TiNx、SiNy 的五种不同组合物中按重量百分比变化。研究了纳米复合涂层的机械和摩擦学性能。除了能量色散 X 射线分析 (EDAX) 和元素映射外，还使用扫描电子显微镜 (SEM) 研究微观结构和磨损形态。为了了解磨损行为和涂层性能之间的相互作用，进行了机械测试，包括环境温度和高温下的显微硬度。进行划痕测试以评估室温下涂层的粘合失效和临界载荷。使用摩擦计在涂有纳米复合材料的碳化钨销和 Ti-6Al-4V 盘之间进行干滑动磨损试验。与单一和二元涂层相比，三元纳米复合涂层表现出优异的摩擦学性能。提供与机械和摩擦学性能相关的有利结果的组合物优选用于涂覆基材以提高基材在各种工业应用中的性能。
