摘要
多主元高熵合金的发现打破了传统多组元合金中存在复杂金属间化合物的桎梏,利用其特有的高熵效应可以生成简单且综合性能优异的相结构。基于该特性,高熵合金具有优异的力学性能、高温性能和耐腐蚀性能等。介绍了高熵合金的成分调控,综述了激光熔覆技术制备高硬度、热稳定及抗高温氧化、耐腐蚀、耐磨损高熵合金涂层的研究现状,展望了激光熔覆高熵合金涂层的发展前景。
Abstract
The discovery of multi-principal high-entropy alloys breaks the shackles of complex intermetallic compounds produced by the traditional multi-component alloys. Based on its unique high-entropy effect, a simple phase structure that exhibits excellent comprehensive performance can be generated. The high-entropy alloys exhibit many unique properties, including mechanical properties, high-temperature properties, and corrosion resistance. This study introduces the composition control of high-entropy alloys. Further, the research status of high-entropy alloy coatings, which are prepared using the laser cladding technology, with high hardness, thermal stability, high-temperature oxidation resistance, corrosion resistance, and wear resistance is reviewed. The development foreground of the laser cladding high-entropy alloy coatings is prospected.
