砂带表面形貌测量与评价研究.

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. [ABSTRACT FROM AUTHOR]
