摘要
通过电沉积工艺研究了在镀液中添加不同尺寸的B4C微粒后所得镀铁层的表面形貌、显微硬度、磨损量和腐蚀速率。结果表明:当B4C微粒尺寸为20μm时,镀层可获得最佳的综合性能;B4C微粒过小,镀层磨损量大;过大,微粒处产生裂纹源,耐蚀性差。
The surface morphology,micro-hardness,wear loss and corrosion rate of iron coating were investigated by adding B4C particles of different sizes in electrodepositing process.The results show that when B4C particle size is 20 μm,the coating can obtain best comprehensive performance;if B4C particles are too small,coating wear loss will be large;and if B4C particles are too big,crack source will form at micro-particles,resulting in poor corrosion resistance.
