摘要： A turbine matrix sleeve in accordance with the invention includes an inner cylindrical structure made up of a first material. The inner cylindrical structure may include multiple blades and multiple channels running between the blades along an outside diameter thereof. The inner cylindrical structure further includes threads, such as right-hand or left-hand threads, on an outer surface thereof. An outer layer, made up of a second material different from the first material, is integrally bonded to the threads. This outer layer may be optionally embedded with hardened inserts or buttons, such as PDC inserts, diamond inserts, TSP inserts, or the like. The threaded surface on the inner cylindrical structure significantly improves the bond between the outer layer and the inner cylindrical structure and creates a mechanical lock therebetween.
摘要翻译： 根据本发明的涡轮机矩阵套筒包括由第一材料构成的内圆柱形结构。 内圆柱形结构可以包括沿其外径在叶片之间延伸的多个叶片和多个通道。 内圆柱形结构还包括在其外表面上的诸如右手或左旋螺纹的螺纹。 由与第一材料不同的第二材料构成的外层与螺纹整体结合。 该外层可以可选地嵌入硬化的插入物或按钮，例如PDC插入物，金刚石插入物，TSP插入物等。 内圆柱形结构上的螺纹表面显着地改善了外层和内圆柱形结构之间的结合，并在其间形成了机械锁。
