摘要: 在Q450NQR1中添加不同含量钒制备含钒新型建筑耐候钢，并对其进行了显微组织、耐蚀性和耐磨性的测试与分析。钒含量对Q450NQR1含钒新型建筑耐候钢试样的腐蚀性能和磨损性能影响较显著。与未添加钒含量的Q450NQR1试样相比，添加0.5%钒的Q450NQR1-0.5V的耐腐蚀性能和耐磨损性能最佳，腐蚀速率减小了45.47%、磨损体积减小了34.38%。从优化含钒新型建筑耐候钢的耐腐蚀性能和耐磨损性能的角度出发，钒含量优选为0.5%。Abstract: In this paper,a new type of weatherproof steel for building containing vanadium was prepared by adding different content of vanadium in Q450 NQR1 steel,and the microstructure,corrosion resistance and wear resistance of the new steel were tested and analyzed.Vanadium has a significant effect on the corrosion and wear properties of the new steel.Compared with Q450 NQR1 samples without vanadium,best corrosion resistance and wear resistance can be obtained for Q450 NQR1-0.5 V samples with 0.5% of vanadium added making the corrosion rate and wear volume reduced by 45.47% and 34.38%,respectively.From the point of view for optimizing the corrosion resistance and wear resistance of the new vanadium-containing building weatherproof steel,the vanadium content is optimized at 0.5%.
