    Abstract: Precursor alpha alumina abrasive particles in a mold are subjected to a drying process that cracks or fractures at least a majority of the precursor abrasive particles into at least two pieces thereby producing abrasive shards having a smaller size than the mold cavity from which they were made. The smaller abrasive shards, once formed, could be reassembled like jigsaw puzzle pieces to reproduce the original cavity shape of the mold from which they were made. The cracking or fracturing of the precursor abrasive particles is believed to occur by ensuring that the surface tension of the abrasive dispersion to the walls of the mold is greater than the internal attractive forces of the abrasive dispersion as the abrasive dispersion is dried within the mold cavity.

    Abstract translation: 将模具中的前体α氧化铝磨料颗粒进行干燥处理，使至少大部分前体研磨剂颗粒破裂或破裂成至少两个，从而产生具有比其制造的模具腔更小的尺寸的磨料碎片。 一旦形成的较小的磨料碎片可以像拼图拼图一样重新组装，以再现其制造的模具的原始腔体形状。 认为前体研磨剂颗粒的破裂或断裂是通过确保研磨分散体在模具腔内干燥的情况下，研磨分散体对模具壁的表面张力大于磨料分散体的内吸力而发生的 。

    Abstract: A method for making an abrasive article having at least two abrasive coatings having different abrasive natures. The abrasive natures can differ, for example, by abrasive particle size, abrasive particle type, abrasive particle shape, filler, surfactant, or coupling agent. In another embodiment, the abrasive article can be a structured abrasive article comprising abrasive composites. In another aspect of the invention, the article can have a coating having a single abrasive nature, where the composites comprising the coating are free of abrasive particles.

    Abstract translation: 一种用于制造具有至少两个具有不同磨蚀性质的磨料涂层的磨料制品的方法。 研磨性质可以不同，例如，通过研磨颗粒尺寸，磨料颗粒类型，磨料颗粒形状，填料，表面活性剂或偶联剂。 在另一个实施方案中，磨料制品可以是包含磨料复合材料的结构化磨料制品。 在本发明的另一方面，制品可以具有单一研磨性质的涂层，其中包含涂层的复合材料不含磨料颗粒。
