    • An abrasive has a plate shape with a flat surface, in which a maximum diameter of the flat surface thereof is in the range of 0.05 mm to 10 mm, and 1.5 to 100 times as the maximum diameter as thick of the adhesive, and the blast processing method is one in which this abrasive is ejected by being inclined at an incident angle with respect to a surface of a product to be treated. The ejected plate-shaped abrasive slides along the surface of the product to be treated while having the flat surface in slidable contact with the surface of the product to be treated which is an object surface to be treated, so that the surface of the product to be treated is flattened by removing the peaks only, without increasing the depth of the valleys of the roughness curve.
    • 研磨剂具有平坦表面的平板形状,其平坦表面的最大直径在0.05mm至10mm的范围内,并且作为粘合剂的最大直径的1.5至100倍,并且爆炸 处理方法是通过相对于待处理产品的表面以入射角倾斜来喷射研磨剂的方法。 排出的板状磨料沿着待处理产品的表面滑动,同时具有与要处理的待处理产品的表面可滑动接触的平坦表面,使得产品的表面 通过仅去除峰而不会增加粗糙度曲线的谷的深度来进行处理。

    • A process for selectively stripping a coating from a component of a turbomachine, and particularly a coating having a ceramic matrix that contains metallic particles dispersed therein that render the coating more difficult to remove from the component after the component has been subjected to elevated temperatures during operation of the turbomachine. The process generally includes immersing the component in an aqueous solution containing ferric chloride, nitric acid, and phosphoric acid, for a duration sufficient to attack the metallic particles in the coating. The component is then removed from the aqueous solution and its surface rinsed of the aqueous solution. The immersing and removing steps are then sequentially repeated a sufficient number of times to sufficiently attack the metallic particles to enable the coating to be mechanically removed from the component.
    • 一种用于从涡轮机组件选择性地剥离涂层的方法,特别是具有包含分散在其中的金属颗粒的陶瓷基体的涂层,其使得在组件在操作期间经受高温之后更难以从组件移除 的涡轮机。 该方法通常包括将组分浸入含有氯化铁,硝酸和磷酸的水溶液中持续足够时间以侵蚀涂层中的金属颗粒。 然后从水溶液中除去组分,并将其表面漂洗水溶液。 然后将浸渍和去除步骤顺序地重复足够的次数以充分攻击金属颗粒,以使涂层能够从组件机械地移除。
