Study of Plasma Electrolytic Nitrocarburising on Surface of Titanium Alloy

在含有硝酸铵、甘油、乙醇的水溶液中,利用等离子体电解渗入技术在Ti6Al4V钛合金表面制备了氮碳共渗层.利用SEM、XRD、GDS以及显微硬度计分析了渗层的形貌、成分、组织和显微硬度,探讨了渗层形成的机理和过程.结果表明:(1)以300V的电压经45min处理制备的渗层总厚度约为100μm,其中化合物层约为20μm,主要由Ti(C,N)相组成;(2)渗层最高显微硬度超过2000HK0.0025.等离子体电解渗入技术可以较快地在钛合金表面制备出厚度大、硬度高的氮碳共渗层.
