摘要： The invention both rotates and oscillates the electrode at the same time to increase the quality of materials deposited onto a substrate during an pulse fusion surfacing process. The PFS spark rate is also varied to further increase the quality and effectiveness of the PFS process. Electrode oscillation keeps the electrode from welding to the substrate surface and electrode rotation maintains even wear on the electrode work surface. An evenly worn electrode surface allows the PFS process to generate more consistent substrate surfaces. In addition, electrode oscillation neutralizes "run away" conditions and varying spark torque that occur with electrodes that are only rotated. The spark rate is varied according to various PFS process parameters (e.g., substrate material) to further improve the quality of the PFS deposition layer. The pulse fusion surfacing process according to the invention is utilized to create knife blades that remain sharp even after extended use due to differential wear between the blade substrate material and the PFS material.

摘要翻译： 本发明同时旋转并振荡电极，以在脉冲熔融表面处理过程中增加沉积在基底上的材料的质量。 PFS火花率也有所不同，以进一步提高PFS过程的质量和有效性。 电极振荡使电极不会焊接到基板表面，电极旋转在电极工作表面上保持均匀的磨损。 均匀磨损的电极表面允许PFS工艺产生更一致的衬底表面。 此外，电极振荡中和“旋转”状态，并且随着仅旋转的电极而发生的变化的火花转矩也会消除。 火花率根据各种PFS工艺参数（例如，衬底材料）而变化，以进一步提高PFS沉积层的质量。 根据本发明的脉冲熔融表面处理方法被用于产生刀片，由于刀片衬底材料和PFS材料之间的差别磨损，即使经过长时间使用也能保持尖锐。

摘要： A radiation detector has a plurality of detector collection element arrays immersed in a radiation-to-electron conversion medium. Each array contains a multiplicity of coplanar detector elements radially disposed with respect to one of a plurality of positions which at least one radiation source can assume. Each detector collector array is utilized only when a source is operative at the associated source position, negating the necessity for a multi-element detector to be moved with respect to an object to be examined. A novel housing provides the required containment of a high-pressure gas conversion medium.
