Abstract

In this study, the corrosion behaviors of composite materials produced by adding different amounts of B₄C in two different antifreeze (50 and 100% monoethylene glycol) environments are investigated. Aluminum matrix composites produced are characterized by microstructure, density, and hardness measurements. Potentiodynamic polarization technique is used in corrosion studies. While the hardness of composite materials produced is increased with increasing amount of B₄C within the materials, the density of materials decreases. As a result of corrosion tests, it is observed that corrosion resistance decreases with the increasing amount of B₄C. The highest corrosion resistance was obtained in the matrix material (AlGr) in 100% antifreeze solution.

Al-B4C 增强复合材料在不同防冻液中的腐蚀行为研究

摘要

在这项研究中，研究了在两种不同的防冻剂（50% 和 100% 单乙二醇）环境中添加不同数量的 B ₄ C 所生产的复合材料的腐蚀行为。生产的铝基复合材料的特征在于微观结构、密度和硬度测量。动电位极化技术用于腐蚀研究。所生产的复合材料的硬度随着材料中B ₄ C含量的增加而增加，但材料的密度降低。作为腐蚀试验的结果，观察到耐腐蚀性随着B ₄ C量的增加而降低。在100%防冻溶液中的基体材料(AlGr)中获得了最高的耐腐蚀性。
