Reclaim of Used Targets
Most modern high power x-ray targets are heavy assemblies manufactured via powder techniques.
During use, only a thin layer of the tungsten surface is altered. Acerde utilizes its proprietary CVD process to replace this layer and give the targets multiple lives.
The reclaim process entails:
- Focal track machining, to remove mudflat layer;
- CVD deposition of a 100%-dense Tungsten-Rhenium layer
- Final grinding to target specification.
The diagram below shows the state of the track between the different steps.
The CVD-deposited material thickness is equivalent to the thickness removed by grinding to ensure the target dimensions remain in specification.
