In this technique, metal or ceramic balls and powder particles are placed inside a vibration chamber.
The vibration causes the balls to accelerate and repeatedly impact the inner metal surface of the chamber.
As a result, the metal surface is rapidly coated with the powder particles.
However, the current methods to manufacture diamond-based coatings present several disadvantages.
They are only suitable for small scale compo- nents with limited possible feedstock/substrate combinations, they typically require complex and expensive pre-processing steps, or they involve the use of toxic waste products.
An industrial push therefore exists to move from current technologies to alternative methods with higher efficiency.
