对非连续增强铝基复合材料的腐蚀、应力腐蚀断裂与氢脆研究的评述

Review on the Corrosion,Stress Corrosion Cracking and Hydrogen Embrittlement of Discontinuously Reinforced Al-Matrix Composites

本文就国内外对非连续增强铝基复合材料,主要是SiC、Al_2O_3颗粒和晶须增强铝基复合材料的腐蚀、应力腐蚀断裂和氢脆的研究现状和主要结论进行了介绍和评价,并为今后的进一步研究提供了一些思路。复合材料的腐蚀形态与铝合金相似,但复合材料的增强体对应力腐蚀断裂和氢脆的、作用不同研究者有不同的结论。

The research status and main conclusions about the corrosion, stress corrosicn cracking and hydrogen embrittlement of discontinuously reinforced Al-matrix compositen, mainly SiC and Al_2O_3 Particulate and whisker reinfor ced Al alloy, in home and abroad, are reviewed, Some study approaehes for following research are discussed. The corrosion Pattern of the composites is Similar as Al alloy, The effect of reinforcement in composite on stress corrosion cracking and hydrogen embrittlement are different from different researcher.
