Effects of Technological Conditions on Microstructure and Properties of In-situ Synthesized WC/W Surface Composites AITranslate
Abstract AITranslate
Tungsten carbide layers with a certain thickness were in-situ synthesized on the surface of sintered tungsten products by high temperature heat treatment in carbon atmosphere protected by hydrogen gas to prepare WC/W surface composites.The effects of heat treatment temperature and tungsten matrix density on microstructure and properties of in-situ synthesized WC/W surface composites were studied by density and hardness test and metallographic microscope.The element composition and phase composition of tungsten carbide layers were analyzed by SEM/EDS and XRD.The results show that high temperature heat treatment temperature has significant influence on the growth thickness and quality of tungsten carbide layer,while tungsten matrix density has no obvious influence on the growth of tungsten carbide layer.When the temperature is lower than 1 800 ℃,the thickness of the tungsten carbide layer is relatively thin and its strength is poor.However,too high temperature will lead to an increase in defects of the tungsten carbide layer.The tungsten carbide layer in-situ synthesized on the surface of tungsten matrix has columnar crystal microstructure and single phase composition,closely combining with tungsten matrix,and the interface is clean and free of impurities.The surface composites can fully exhibit the excellent properties of the two materials at high temperature.
