摘要
为探索高强度高模量铝基复合材料的腐蚀性能,采用粉末冶金工艺制备了增强相体积分数为17%、20%的铝基复合材料。腐蚀研究结果表明,铝基复合材料的腐蚀与基体关系密切,复合材料产生的剥落腐蚀及电化学腐蚀与基体相比敏感性不强,增强相的加入使材料的晶间腐蚀、盐雾腐蚀性能恶化。
In order to explore the mechanical and corrosion properties of the high strength and high modulus aluminum matrix composites,the aluminum matrix composites with reinforcing phase of 17%and 20%of volume fraction are prepared by powder metallurgy.The corrosion research results show that the corrosion of the aluminum matrix composites is closely related to the matrix.The exfoliation corrosion and electrochemical corrosion of the composites are less sensitive than those of the matrix.The addition of reinforcing phase deteriorates the intergranular corrosion and salt spray corrosion of the materials.
