热氧化TC4合金在模拟油田介质中的腐蚀磨损行为
Corrosive Wear Behavior of Thermal Oxidized TC4 Alloy in Simulated Oilfield Medium
【摘要】 采用热氧化技术对TC4合金进行表面处理,研究了热氧化TC4合金在模拟油田介质中的腐蚀磨损行为。结果表明:热氧化层主要由金红石相组成,热氧化层具有更高的表面硬度,更低的磨损失重和比磨损率。热氧化处理显著提高了TC4合金在模拟油田介质中的抗腐蚀磨损性能。
【Abstract】 Surface treatment of TC4 alloy was carried out by Thermal oxidation(TO) process. Corrosive wear behavior of the TO treated TC4 alloy in simulated oilfield medium was investigated. The results show that the obtained TO layer is mainly composed of rutile TiO2 phase. The TO layer has higher surface hardness and lower mass loss and specific wear rate. TO treatment significantly improves the corrosive wear resistance of TC4 alloy.
