What are the anode and cathode in plasma spraying?

In plasma spraying technology, the spray gun is a crucial component, and the core parts of the spray gun are the cathode and the anode.

Introduction to Plasma Spraying and the Core Component—The Nozzle

Plasma spraying involves generating a direct-current arc between a cathode (electrode) and an anode (nozzle). This arc heats and ionizes the introduced working gas into a high-temperature plasma, which is then ejected from the nozzle to form a plasma flame. After being fed into the plasma jet by a powder-feeding gas, the powder particles are melted, accelerated, and sprayed onto the pre-treated substrate surface, thereby forming a coating.

As the core component of a plasma spraying system, the 9MB electrode features several innovative designs that significantly enhance both the process quality and cost-effectiveness of carbon fiber surface coatings.
