铁基耐磨堆焊复合涂层组织调控与强韧化研究进展
Research Progress on Micro structure Regulation and Strengthening-Toughening of Iron-Based Wear-Resistant Hardfacing Composite Coatings
摘要
Abstract
Iron-based wear-resistant hardfacing composite coating is an important surface technology to improve the service life of mechanical parts,but it faces the contradiction between high wear resistance and strong toughness for a long time.This paper systematically reviews the latest research progress of the coating in interface regulation and strengthening and toughening.Firstly,the main limitations and failure mechanisms of the coating are analyzed.It is pointed out that the crack sensitivity induced by brittle hard phase,the microstructure gradient caused by interface dilution,the performance reversal caused by excessive strengthening phase and the subsurface instability under complex wear conditions are the core bottlenecks.Secondly,the iron-based wear-resistant hardfacing alloys are classified and reviewed according to Fe-Cr,Fe-Mn and Fe-Cr-Ni systems,and the microstructure characteristics and the strengthening as well as toughening mechanism of each system are expounded.On this basis,the mechanisms of strengthening and toughening modification in the iron-based wear-resistant alloys via the alloy composition optimization design,the composite process and the multi-field coupling technology are emphatically reviewed.Finally,it is pointed out that the collaborative design of hard phase-matrix-interface is an important direction for future development.关键词
