Preparation of powder metallurgy slab, billet and then by rolling to produce high-power ceramic transmitting tubes with thin gate. First by acid etched into the net, and then by plating high temperature soldering processes shaping the gate from the launch tube, the use of temperature up to 1300-1400 degrees Celsius, life requirements of up to thousands of hours, so these sheets are very strict quality requirements, must ensure that (1) no peeling stratification; (2) homogeneous, acid etching thorough, clear the grid does not produce adhesions and jagged;. (3) after the high temperature setting, grid deformation and brittle fracture can not. the specific mode of operation as follows:
1. refined titanium hydride powder and zirconium hydride powder particle size (less than 5 microns), an appropriate increase in the sintering temperature (controlled at about 2050 degrees Celsius), can produce for TZM sheet rolling slab, subsequent cold rolling process significantly reduce the generation of scale defects from.
2. sintering at 1350-1450 degrees Celsius blooming slab can guarantee the normal rolling.
3. rolling processing rate of 70% of the total thickness of 8 mm, were 1550 ° C annealing, cold rolling process to avoid stratification phenomenon.
According to the above process to produce high-power ceramic transmitting tubes with thin gate room and high temperature mechanical properties meet the requirements.
