Abstract

Glass-ceramics, known for their thermal stability and strong adhesion to metal substrates, are widely used as protective coatings for high-temperature application. But they usually suffered from inherent brittleness and high susceptibility to cracking. Traditional approaches to improve fracture toughness via incorporation of metal particles have often failed due to the ongoing reactions between the particles and the corrosive media. In this study, thermal shock resistance was significantly enhanced by doping oxidation-resistant soft metal particles, specifically Ag. The interface crystallization increases bonding strength, ensures complete plastic deformation of Ag particles under thermal stress, thereby enhancing fracture toughness and preventing matrix cracking. After 100 thermal shock cycles at 700 °C, the Ag-doped glass-ceramic coating exhibited superior performance, with high oxidation resistance, no crack initiation and a minimal mass loss of 0.04 mg/cm². This approach addresses the brittleness challenge of glass-ceramics, while fully utilizing the advantage of oxidation resistance.

ag增韧玻璃陶瓷涂层，在700°C的热冲击下具有优异的抗氧化和抗剥落性能

微晶玻璃以其热稳定性和对金属基板的强附着力而闻名，被广泛用作高温应用的保护涂层。但它们通常具有固有的脆性和高的开裂敏感性。通过加入金属颗粒来提高断裂韧性的传统方法由于颗粒与腐蚀介质之间的持续反应而经常失败。在本研究中，通过掺入抗氧化软金属颗粒，特别是Ag，可以显著提高材料的抗热震性。界面结晶提高了结合强度，保证银颗粒在热应力作用下完全塑性变形，从而提高断裂韧性，防止基体开裂。经过100次700°C的热冲击循环后，掺银玻璃陶瓷涂层表现出优异的性能，具有较高的抗氧化性，无裂纹萌生，质量损失最小，为0.04 mg/cm²。这种方法解决了玻璃陶瓷的脆性挑战，同时充分利用了抗氧化的优势。

期刊介绍： The Journal of the European Ceramic Society publishes the results of original research and reviews relating to ceramic materials. Papers of either an experimental or theoretical character will be welcomed on a fully international basis. The emphasis is on novel generic science concerning the relationships between processing, microstructure and properties of polycrystalline ceramics consolidated at high temperature. Papers may relate to any of the conventional categories of ceramic: structural, functional, traditional or composite. The central objective is to sustain a high standard of research quality by means of appropriate reviewing procedures.
