控制栅栅网是栅控脉冲行波管的关键部件之一。这种栅网是由钼片经电火花加工制成的。制成的栅网的网丝上常常有毛刺和其它黑色附着物。这些附着物不易清除干净并因此往往造成管子打火,栅极截获电流偏大,从而影响管子的性能和成品率。因此,设法将栅网表面处理干净是十分重要的。 清除栅网表面附着物目前通常用手工去除毛刺和金刚砂超声处理,但效果较差。为了寻求一种较有效的处理工艺,我们先用离子探针和俄歇电子谱仪对网丝表面进行了组 Control grid is one of the key components of gated pulse traveling wave tube. This grid is made of molybdenum EDM. Mesh made of mesh often have burrs and other black attachments. These attachments are not easily cleaned and therefore tend to cause the tube to ignite and the gate intercept current is too large, which affects the tube performance and yield. Therefore, try to clean the surface of the grid is very important. Removal of grid surface attachments is currently used by hand to remove burrs and emery, but the effect is poor. In order to seek a more effective treatment process, we first use the ion probe and Auger electron spectrometer on the mesh surface group
