摘　　要：为研究微弧氧化时间对活塞用铝合金陶瓷膜层生长规律的影响,对ZL109铝合金进行不同时间的微弧氧化。采用粗糙度仪、SEM、XRD以及Image J软件研究了微弧氧化时间对膜层表面形貌、表面粗糙度、表面孔隙率、膜层厚度、增长速率和相组成的影响。结果表明:随着微弧氧化时间的增加,膜层表面粗糙度和膜层厚度增加,膜层表面的“火山岩”状形貌特征也越明显。膜层表面孔隙率和增长速率随时间的增加呈先增加后减小的趋势;在微弧氧化时间为20 min时,膜层表面孔隙率最大,为20.2%;在10~20 min,膜层增长速率最大,为2.1μm/min。随着微弧氧化时间的增加,膜层中γ-Al_(2)O_(3)和α-Al_(2)O_(3)的含量逐渐增加。In order to study the effect of micro-arc oxidation(MAO)time on the growth regularity of ceramic coating of aluminum alloy for piston,ZL109 aluminum alloy was treated by MAO for different time.The effects of oxidation time on the surface morphology,surface roughness,surface porosity,coating thickness,growth rate and phase composition of the coating were investigated by roughness meter,SEM,XRD and Image J software.The results show that the surface roughness and thickness of the coating increase with the increase of oxidation time,and“volcano deposit”characteristic is also more obvious.However,the porosity and growth rate first increase and then decrease with increasing oxidation time.The surface porosity of the coating is the largest,when the oxidation time is 20 min,which is 20.2%.During the period of 10 min to 20min,the growth rate is the largest,which is 2.1μm/min.Meanwhile,the content ofγ-Al_(2)O_(3)andα-Al_(2)O_(3)in the coating also increase gradually with the increase of oxidation time.
