中文摘要 | 本研究主要是在探討SiC<p>之粒徑(46μm、80μm)及添加量(5 wt%、10 wt%) 固溶處理(480℃,3小時)人工時效處理時間(150℃,1、3、10小時)及腐蝕磨耗環境(蒸 餾水及3.5wt%鹽水)等實驗條件不同時,對於SiC<p>╱A390鋁基複合材料鑄件機械性質 及腐蝕磨耗行為之影響。 實驗結果顯示,SiC<p>粒徑及添加量增加可提升SiC<p>╱A390鋁基複合材料鑄件之 硬度值及耐腐蝕磨耗性,且以添加量增加對硬度值的提升效果最為顯著。SiC<p>添加量為 5wt%時,SiC<p>粒徑增加可提升抗拉強度值,但添加量為10wt%時,卻會造成抗拉強度值 的降低。 人工時效處理時間增至10小時後,雖可提升A390鋁合金之抗拉強度值,及SiC<p>╱ A390鋁基複合材料鑄件之硬度值,但對SiC<p>╱A390鋁基複合材料鑄件之抗拉強度值及 耐腐蝕磨耗性並沒有明顯影響。 在腐蝕磨耗環境方面,SiC<p>╱A390鋁基複合材料鑄件與A390鋁合金在蒸餾水中之 耐腐蝕磨耗性皆比在3.5wt%鹽水中為佳,而其耐腐蝕性則會隨著SiC<p>添加量之增加而降 低。 |
英文摘要 | The primary purpose of this research was to investigate the effects of SiC particles (SiC<p>)size(46μm、80μm)and the amount of reinforcements(5 wt%、10 wt%), solid solution treatment(480℃,3hours), articificial aging(150℃,1、3、10hours) and the environments of corrosion wear(distilled water、3.5wt%NaCl solution)on the mechanical properties and corrosion wear behavior of SiC<p>╱A390Al-matrix composites. The results show that the increasing of Sic<p> size and the amount of reinforcements increased the hardness and the corrosion wear resistance of Sic<p>╱A390 Al-matrix composites. At 5wt% reinforcements, the increasing of the SiC<p> size increased the tensile strength, but at 10wt% the tensile strength was decreased. The tensile strength of A390 aluminum alloy was increased with the increasing of the holding time of artificial aging. For SiC<p>╱A390Al-matrix composites, the holding time of artificial aging has no significant influence on the tensile strength and the corrosion wear resistance. The corrosion wear resistance of SiC<p>╱A390 Al-matrix composites and A390 aluminum alloy in the distilled water was better than that in the 3.5wt% NaCl solution. However, the corrosion resistance decreased with the increasing of the amount of the SiC<p> reinforcements. |
