Influencing and disturbing variables in relation to the feed stabilities of powder feed systems with different control concepts
The precise and stable feeding of powders is a basic prerequisite for thermal spraying and laser beam surface welding in order to be able to manufacture high-quality coatings and structures. The volumetric disc feeder fr...
Compaction, smoothing and hardening of thermally sprayed coatings by means of ultrasonic machining
The article deals with the ultrasoni-cally assisted post-treatment of thermally sprayed (TS) coatings. Ultrasonic (US) technology is optimised for various materials as examples (iron-based, zinc and copper sprayed coatin...
