钴基高温合金氧化行为研究进展
Research progress in oxidation behavior of cobalt-based superalloys
摘要
Abstract
Cobalt-based superalloys are widely used in aerospace,energy power,and nuclear industries due to their excellent resistance to thermal corrosion and fatigue,as well as good weldability.However,high-temperature oxidation leads to performance degradation of the alloys,becoming a key factor limiting their service life.This paper reviews the progress in the study of oxidation behavior of cobalt-based superalloys,focusing on the different stages of oxidation and their mechanisms of the oxidation process.It further explores the effects of alloying elements and temperature on the formation and evolution of oxide scales,and critically analyzes the limitations and challenges of current research.Finally,it points out that future key research directions include the design of novel cobalt-based superalloy compositions and the optimization of synergistic mechanisms,control of oxide scale and phase transformations,as well as conducting oxidation studies under dynamic environments combined with intelligent methods to accelerate materials optimization.关键词
