Abstract

Corrosion protection of metals is essential for a wide range of technological applications, and coating metal surfaces with protective materials is a commonly employed method to achieve this. Among these, TiO₂ coatings are extensively used due to their excellent photocatalytic properties, their applications in sensing and solar cells, and enhancing the corrosion and wear resistance of metal surfaces. Recent advancements have focused on the incorporation of carbide particles, such as B₄C, to further improve the performance of TiO₂ coatings. In this study, TiO₂ coatings containing 0–3.25 wt% B₄C were applied to a 316 L stainless steel substrates using the sol-gel method. The coatings were characterized by XRD and SEM-EDS analyses, and their wear and corrosion properties were evaluated using ball-on-disc wear tests and corrosion tests in NaCl solutions. The results demonstrated that lower concentrations of B₄C led to improved wear resistance, likely due to the formation of a durable tribolayer, while higher concentrations reduced the wear resistance, attributed to increased oxidation and the formation of brittle phases. Corrosion resistance was enhanced in coatings containing 0.25 wt% and 1.25 wt% B₄C, which can be attributed to the formation of protective B₂O₃ phases. However, at higher B₄C concentrations, the corrosion rate increased, primarily due to the presence of cracks in the coating structure. Overall, the addition of 0.25 wt% B₄C to the TiO₂ coating significantly improved wear and corrosion resistance, indicating its potential as an effective additive for protective coatings.

通过溶胶-凝胶法在 316 L 不锈钢上涂覆 B4C 添加型 TiO2 涂层的微结构、摩擦学和腐蚀行为

金属的防腐保护对于广泛的技术应用至关重要，而在金属表面涂覆保护材料是实现这一目标的常用方法。其中，二氧化钛涂层因其优异的光催化性能、在传感和太阳能电池中的应用以及增强金属表面的耐腐蚀性和耐磨性而被广泛使用。最近的研究重点是加入碳化物颗粒（如 B4C），以进一步提高二氧化钛涂层的性能。在本研究中，采用溶胶-凝胶法将含 0-3.25 wt% B4C 的 TiO2 涂层涂覆到 316 L 不锈钢基底上。通过 XRD 和 SEM-EDS 分析对涂层进行了表征，并使用球盘磨损试验和氯化钠溶液腐蚀试验对涂层的磨损和腐蚀特性进行了评估。结果表明，较低浓度的 B4C 可提高耐磨性，这可能是由于形成了持久的摩擦层，而较高浓度的 B4C 则会降低耐磨性，这归因于氧化作用加剧和脆性相的形成。在含有 0.25 wt% 和 1.25 wt% B4C 的涂层中，耐腐蚀性得到了增强，这可能是由于形成了保护性的 B2O3 相。然而，当 B4C 浓度较高时，腐蚀速率增加，这主要是由于涂层结构中出现了裂缝。总之，在 TiO2 涂层中添加 0.25 wt% 的 B4C 能显著提高耐磨性和耐腐蚀性，这表明它有潜力成为一种有效的保护涂层添加剂。

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
