W-4.9Ni-2.1Fe高比重合金的摩擦磨损行为
Frictional wear behavior of tungsten heavy alloys 93W-4.9Ni-2.1Fe
摘要
Abstract
Tungsten heavy alloys (W-4.9Ni-2.1Fe) were successfully prepared by high-energy ball milling (HEBM) and spark plasma sintering (SPS) technique, and the influence of milling time on microstructure and friction and wear behavior were studied. The results show that the Ni and Fe elements still exists in the form of simple substance phase when the milling time is 2 h. With prolonging the milling time, Ni (Fe) dissolves into the lattice of W and forms a supersaturated solid solution of W matrix, the W phase diffraction peak becomes increasingly wider and its intensity continues to decline. At the same time, the relative density of the sample decreases. Appropriate milling time (24 h) can not only ensure the content of binding phase and its uniform distribution, but also obtain the stability of the alloy composition by not introducing too much impurity ele-ment, and thus the wear resistance property of the alloy being the best.关键词
