| 摘 要： | 采用电沉积法制备非晶态Cr-C合金镀层,利用X射线衍射和扫描电子显微镜对镀层结构和形貌进行表征,并对镀层进行硬度、耐磨性、耐腐蚀性及热处理实验。结果表明,非晶态Cr-C合金镀层硬度、耐磨性和耐腐蚀性均明显优于普通晶态镀层;施镀态镀层硬度为997HV0.025,在300～600℃范围内发生晶化反应并析出Cr7C3、Cr23C6化合物,硬度可达1610HV0.025。

| Abstract: | Amorphous Cr-C alloy coating was prepared by electrodepositing.The microstructure,composition and surface morphology of the coating were detected by X-ray diffraction,SEM and EDS.The microhardness,wear resistance and corrosion resistance of the coating were tested,and heat treatment experiment was carried out.The results show that amorphous Cr-C alloy coating owned preferable properties on aspects of microhardness,wear resis-tance and corrosion resistance.The crystallization evolution of the coating begin at 300℃ and finish around 600℃,and intermetallic compound Cr7C3 and Cr23C6 appear in the evolution process.It prompt microhardness of 1610HV0.025,far greater than as deposited of 997HV0.025. |
