作者利用入射速度为40m/s的80~#和100~#白刚玉砂冲击超硬质膜,测定入射粒子量与膜剥离之间的定量关系,确定造成底材开始显露所需的粒子用量(孕育剂量)和冲蚀坑中心部位的膜全部剥离时的最低粒子用量(临界剂量),并以两者之差作为判据,收... 作者利用入射速度为40m/s的80~#和100~#白刚玉砂冲击超硬质膜,测定入射粒子量与膜剥离之间的定量关系,确定造成底材开始显露所需的粒子用量(孕育剂量)和冲蚀坑中心部位的膜全部剥离时的最低粒子用量(临界剂量),并以两者之差作为判据,收到了与划痕法通过临界载荷评价膜-底材结合强度的同样效果。试验结果证明,孕育剂量与膜厚呈正变关系,因而通过它可以先求出膜厚,再求出剥离单位厚度膜层所消耗的粒子量(线冲蚀系数),并用其作为膜-底材结合强度的判据,可以扣除膜厚的影响。作者认为,冲蚀法的主要优点是设备简单、操作方便、取样面积大、代表性好,能为各类薄膜工艺提供可信的判据。 展开更多

Taguchi technique was used to predict the influence of processing parameters on the erosive wear behavior Al7034-T6composite reinforced with SiC and Al2O3particles in different mass fractions.These hybrid metal matrix composites(HMMCs)werefabricated by using a simple technique called stir casting technique.Scanning electron microscope(SEM)was used to study thesurface morphology of the composite and its evolution according to processing time.The design of experiment(DOE)based onTaguchi’s L16orthogonal array was used to identify various erosion trials.The most influencing parameter affecting the wear rate wasidentified.The results indicate that erosion wear rate of this hybrid composite is greatly influenced more by filler content and impactvelocity respectively compared to other factors.This also shows the significant wear resistance with the increase in the filler contentsof SiC and Al2O3particles,respectively. 展开更多
