摘要
采用脉冲电源在不同电压下对Ti15-Mo合金材料表面进行液相等离子体电解试验,研究电压对含Ti(C,N)等物相的陶瓷氧化膜生长的影响。结果表明,随着处理电压的增大,样品表面形貌的孔洞数量和尺寸发生明显的变化。其中350 V高电压下,试样表面产生裂纹和尺寸较大的凹坑;渗层厚度随处理电压的增大而增大,厚度最大可达约100μm;而膜层的硬度随着电压的升高,呈现先升高后降低的趋势,当电压上升至300 V时,试样平均硬度达到最大值1805.35 HV,约为基材的4.7倍,Ti15-Mo合金经液相等离子体处理后,耐蚀性会提升,但电压过高时所制备的涂层耐蚀性会有所降低。
Liquid phase plasma electrolysis experiments were conducted on the surface of Ti15 Mo alloy material using a pulse power supply at different voltages to investigate the effect of voltage on the growth of ceramic oxide films containing Ti(C,N)and other phases.The results indicate that with the increase of processing voltage,the number and size of pores on the surface of the sample undergo significant changes.At a high voltage of 350 V,cracks and larger pits appear on the surface of the sample.The thickness of the infiltration layer increases with the increase of processing voltage,and the maximum thickness can reach about 100μm;The hardness of the film layer shows a trend of first increasing and then decreasing with the increase of voltage.When the voltage rises to 300 V,the average hardness of the sample reaches the maximum value of 1805.35 HV,which is about 4.7 times that of the substrate.After liquid-phase plasma treatment,the corrosion resistance of Ti15 Mo alloy will be improved,but the corrosion resistance of the coating prepared under high voltage will be reduced.
