摘要
以高强钢为基体材料,采用电镀技术在其表面制备镍-铬合金耐腐蚀涂层。为探究镍含量对材料性能的影响,制备了镍的质量分数分别为0、1.2%、1.5%、1.8%的系列样品,并评估了其在风蚀环境中的耐久性。结果表明:当镍的质量分数为1.5%时,复合材料的抗冲蚀性能最优。在吹沙角度为20°、速度为35 m/s的条件下,该材料表现出卓越的力学性能:弯曲模量为210 GPa,弯曲强度为850 MPa,拉伸模量为220 GPa,抗拉强度为950 MPa,各项性能均保持较高水平。微观结构分析显示,其组织结构均匀致密。即使在干湿循环与风蚀的双重作用下,材料仍保持完整结构,展现出优异的耐久性。这为开发高性能抗风蚀材料提供了重要的试验依据和理论指导。
Using high‐strength steel as the base material,nickel‐chromium alloy corrosion‐resistant coatings were prepared on its surface by electroplating technology.To explore the influence of nickel content on the material properties,a series of samples with nickel mass fractions of 0,1.2%,1.5%,and 1.8%respectively were prepared,and their durability in the wind erosion environment was evaluated.The results show that when the mass fraction of nickel is 1.5%,the erosion resistance of the composite material is the best.Under the conditions of a sand‐blowing angle of 20°and a speed of 35 m/s,this material exhibits outstanding mechanical properties.The flexural modulus is 210 GPa,the flexural strength is 850 MPa,the tensile modulus is 220 GPa,and the tensile strength is 950 MPa.All properties remain at a relatively high level.Microstructure analysis shows that its tissue structure is uniform and dense.Even under the dual effects of dry‐wet cycles and wind erosion,the material still maintains its complete structure and demonstrates excellent durability.This provides important experimental basis and theoretical guidance for the development of high‐performance wind‐resistant materials.
