摘要: 采用非接触测量方法对锆刚玉砂带(P120,P320)与陶瓷氧化铝砂带(P120)三维形貌进行测量与评价.结果表明:锆刚玉砂带和陶瓷氧化铝砂带磨粒凸出高度分别呈正态分布、右偏态分布.锆刚玉砂带和陶瓷氧化铝砂带磨粒凸出面积均呈右偏态分布.磨粒凸出高度和凸出面积随磨料粒度的减小而减小,陶瓷氧化铝砂带磨粒凸出高度和凸出面积均小于同粒度锆刚玉砂带.砂带磨粒几何外形均近似呈球顶圆锥体.磨料粒度对磨粒球顶半径影响显著,即粒度越小,球顶半径越小,但对锥顶角影响不明显.同粒度的两种磨料砂带的磨粒球顶半径及锥顶角差异较大.

Abstract: The non-contact measurement method is used to measure and evaluate the three-dimensional morphology of zirconia abrasive belts(P120, P320)and ceramic alumina belt(P120). The results show that the protrusion height of the zirconia abrasive belt and ceramic alumina belt is in the normal distribution and right-skewness distribution respectively. The protrusion area of the zirconia abrasive belt and ceramic alumina belt is both in the right polarized distribution. The protrusion height and area of abrasive grains decrease with the decrease of grain size. The protrusion height and area of abrasive grains in the ceramic alumina belt are smaller than those in the zirconia abrasive belt. The geometric shapes of the abrasive grains of the abrasive belts are similar to the spherical-top cone. The grain size has a significant effect on the spherical-top radius, i.e., the smaller the grain size, the smaller the spherical-top radius, but the effect on the cone apex angle is not significant. There are great differences in the spherical-top radius and cone apex angle of the two abrasive belts with the same particle size.
