    Abstract: An abrasive coating for a substrate including a metallic based bond coat layer; a top layer; and an intermediate layer between the metallic based bond coat layer and the top layer. A method of applying an abrasive coating including applying a metallic based bond coat layer onto a substrate; grading an intermediate layer into the metallic based bond coat layer to form a graded transition between the metallic based bond coat layer and the intermediate layer; and grading a top layer into the intermediate layer to form a graded transition between the intermediate layer and the top layer.

    Abstract: A cooling system for a turbine engine includes a structure defining a fluid passageway. The fluid passageway includes an impingement surface. A first opening into the fluid passageway is also included. The first opening is disposed opposite the impingement surface of the fluid passageway such that airflow entering the fluid passageway impacts the impingement surface. An agglomerate retention structure is disposed on the impingement surface. The agglomerate retention structure holds particulates impacting the impingement surface entering through the opening. A turbine engine is also disclosed.

    Abstract: A method for forming a component having an abrasive portion includes forming the component and selectively forming a coating on the component using electric spark deposition to form the abrasive portion. A method for coating a blade tip with an abrasive material includes forming a blade having a tip and depositing a coating on the blade tip using electric spark deposition. A method includes providing a casing having an inner diameter surface, locating an abradable coating on a portion of the inner diameter surface, providing a blade configured to rotate within the casing and having a blade tip where the blade tip and the inner diameter surface of the casing form a seal, and depositing an abrasive coating on the blade tip using electric spark deposition so that the abrasive coating and abradable coating interact during rotation of the blade within the casing.

    Abstract translation: 用于形成具有研磨部分的部件的方法包括形成部件并且使用电火花沉积选择性地在部件上形成涂层以形成磨料部分。 用研磨材料涂覆刀片尖端的方法包括形成具有尖端的刀片，并使用电火花沉积在刀片尖端上沉积涂层。 一种方法包括提供具有内径表面的壳体，将可磨损涂层定位在内径表面的一部分上，提供构造成在壳体内旋转并具有叶片尖端的刀片，其中刀尖和内径表面 套管形成密封件，并且使用电火花沉积将磨料涂层沉积在刀片尖端上，使得研磨涂层和可磨损涂层在壳体内的刀片旋转期间相互作用。
