AlxCrCuFeNi2多主元高熵合金的摩擦磨损性能
Friction and Wear Properties of AlxCrCuFeNi2 High-entropy Alloys with Multi-principal-elements
摘要
Abstract
Orthogonal test was carried out with ball-on-disc friction and wear tester in dry ,deionized water ,and simulated rain water under three loads (5 ,10 ,15N) ,respectively .The behavior of two materials at different loads under different environment was compared ,the friction and wear proper-ties of the alloys under the simulated service situation was explored .The composition of the samples was examined by X-ray diffraction (XRD) .The contour of wear scars was detected by a three-dimen-sional surface profiler based on scanning white light interferometry .Optical electron microscope is used to observe the structure .The morphology of the worn surfaces were observed by scanning elec-tron microscopy (SEM ) and the wear mechanism was analyzed .Results show that due to the increase of Al ,the body-centered cubic phase (bcc) substitutes the face-centered cubic (fcc) w hich attributed to the high hardness of Al1 .3 CrCuFeNi2 leading to good wear property .In dry condition ,the wear mechanism are oxidation ,adhesion ,plastic deformation ,and mild abrasive wear while in liquid ,the abrasive is dominated along with oxidation and slight adhesive behavior.关键词
