摘要

为提高TC11钛合金在高温恒载拉伸条件下的抗热盐应力腐蚀开裂性能，采用超声表面轧制工艺（USRP）对其进行了加工。通过调整加工工序的数量，USRP产生了精细的表面光洁度，并引入了热稳定的压缩残余应力（CRS）场。通过钉住和缠结高密度位错来维持CRS的稳定性，有效抑制热机械暴露过程中的应力松弛。光滑的表面减少了局部应力集中，限制了CRS重新分布。此外，USRP促进了致密的非晶纳米复合氧化膜的快速发展，该氧化膜有效地阻隔了腐蚀物质并减轻了氧致脆。这些综合效应显著增强了TC11合金的抗HSSCC能力，证明了USRP作为一种强大的表面工程技术的潜力，可以延长钛合金在腐蚀性高温盐环境中的使用寿命。

Surface integrity engineering via ultrasonic surface rolling for enhanced hot salt stress corrosion cracking resistance of TC11 alloy

Ultrasonic surface rolling processing (USRP) was applied to TC11 titanium alloy to improve its resistance to hot salt stress corrosion cracking (HSSCC) under high-temperature constant-load tensile conditions. By tailoring the number of processing passes, USRP produced a refined surface finish and introduced a thermally stable compressive residual stress (CRS) field. The CRS stability was maintained through the pinning and entanglement of high-density dislocations, effectively suppressing stress relaxation during thermal-mechanical exposure. The smoother surface reduced local stress concentrations and limited CRS redistribution. In addition, USRP promoted the rapid development of a dense amorphous–nanocrystalline composite oxide film, which served as an effective barrier to corrosive species and mitigated oxygen-induced embrittlement. These combined effects markedly enhanced the HSSCC resistance of TC11 alloy, demonstrating the potential of USRP as a robust surface engineering technique for extending the service life of titanium alloys in aggressive high-temperature salt environments.

期刊介绍： Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance: A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting. B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
