Effects of Heating Treatment on Friction and Wear Properties of Novel High Aluminum Bronze Alloy

摘要

摘要: 以铜铝合金为基体添加适量的镍、铁、锰元素, 在金属型中制备了一种多元铝青铜合金, 利用扫描电镜、摩擦磨损试验机等研究了固溶时效热处理对该合金摩擦磨损性能的影响。结果表明: 铸态合金经过950 ℃×2 h固溶+ 550 ℃×4 h时效后的显微组织仍由α、β′、γ2和κ相组成, κ相和γ2相弥散分布于基体组织中, 提高了合金的硬度、抗拉强度, 但使其塑性降低; 相同条件下, 固溶时效态合金的磨损量和摩擦因数低于铸态的, 具有良好的耐磨性能。

Abstract: A multicomponent aluminum-bronze alloy was prepared by adding some elements(such as Ni, Fe, Mn) based on the Cu-Al alloy and then being casted in metal mold. The effect of heat treatment of solid solution and aging treatment on friction and wear properties of the alloy was studied by scanning electron microscopy and friction and wear testing. The results show that the alloy was composed mainly of α, β′, γ2 and κ phases after solid solution at 950 ℃ for 2 hours and aging at 550 ℃ for 4 hours, γ2 and κ phases distributed in the matrix, which increased the alloy′s hardness and tensile strength and decreased the alloy′s plasticity. Comparing with the cast alloy, the alloy in solid-solution and aging state had lower wear mass loss and friction coefficient, and had good wear resistantance under the same conditions.
