【摘要】 在实际工业应用中,对不同的产品表面粗糙度有不同的要求,因此,在利用表面处理技术对产品进行表面处理时,其对产品表面粗糙度的影响成为必须考虑的因素。采用微弧氧化技术,以LY12铝合金为试验样品,通过改变不同的微弧氧化功率,制备相应的铝合金陶瓷膜,分别对陶瓷膜进行SEM分析及表面粗糙度测量,得出铝合金陶瓷膜表面粗糙度随微弧氧化功率的变化曲线,研究了氧化功率对铝合金陶瓷膜表面粗糙度的影响。结果表明:微弧氧化功率对铝合金陶瓷膜表面粗糙度的影响非常明显,随着微弧氧化功率的提高,陶瓷膜粗糙度随之增大。并从机理方面进一步做了分析。更多还原

【Abstract】 It is imperative to take into account the effect of surface treatment on the surface roughness of various products, because different products in industrial application usually require different surface roughness. In this respect, aluminum alloy ceramic coatings were prepared on LY12 alloy using microarc oxidation at different anodic oxidation powers. The effect of the oxidation power on the surface roughness of the Al alloy ceramic coating was investigated by plotting the surface roughness vs. oxidation power curves based on scanning electron microscopic analysis and roughness measurement. It was found that the anodic oxidation power had a significant effect on the surface roughness of the microarc oxidation coating on the Al alloy substrate. Namely, the surface roughness of the coating increased with raising anodic oxidation power.更多还原
