Next-generation High-strength Ceramic Materials for Deep-sea Equipment and Structural Analysis

摘要:

深海装备在服役过程中需要抵抗海水及应力腐蚀，承受载荷对结构的考验及深海环境的高压强， 这对材料的综合性能提出了巨大挑战。以氧化铝为代表的高强度陶瓷材料具有耐腐蚀、质量轻、高强度等特点，在深海装备应用中具有巨大潜力。对多种高强度陶瓷材料进行了分析比较，并针对深海应用的要求讨论了材料选型和缺陷要求，为下一代深海装备材料的发展提供了参考。

Abstract:

The deep-sea equipment in service needs to resist seawater and stress corrosion and withstand the test of load on the structure and the high pressure and strength of deep-sea environment，which has posed great challenges to the comprehensive performance of materials. High-strength ceramic materials represented by aluminum oxide possess multiple characteristics of corrosion resistance，light weight and high strength，showing great potential in the application of deep-sea equipment. In this paper，a variety of high-strength ceramic materials are analyzed and compared，and the material selection and defect requirements are discussed according to the demand of deep-sea applications，providing a reference for the development of the next generation of deep-sea equipment materials.
