Y2O3对W-4.9Ni-2.1Fe合金摩擦磨损行为的影响
Effect of Y2O3 on Friction and Wear Behavior of W-4.9Ni-2.1Fe Alloy
摘要
Abstract
The W-4.9Ni-2.1Fe alloy with different addition of Y2O3was prepared by high energy ball milling and spark plasma sintering techniques,the microstructure,mechanical property,friction and wear behavior of the high density alloy were investigated by the Rockwell hardness tester,X-ray diffractometer,reciprocating friction and wear tester,3D profiler,etc.The results show that adequate doping of the trace Y2O3 can effectively inhibit the grain size,promote the γ-(Ni,Fe) bonding phase and tungsten particles uniformly distribute,increase the relative density,hardness,friction and wear properties.But the excessive Y2O3 addition can easily aggregate at grain boundary,weaken the inhibition effect,and decrease the mechanical and wear properties of the alloy.So the addition of Y2O3 should be appropriate.When the adding mass fraction of Y2O3 particles is 0.4％,the comprehensive performance of the alloy is the best.关键词
