Abstract: | The paper presents three innovative diagnostics for application to the plasma spraying process. With plasma computer tomography, the plasma jet is investigated by recording its radiation under several directions. The laser-based particle shape imaging technique is applied for determining dynamic and geometric parameters of spray particles within the plasma jet. The particle flux imaging method, which allows the characterisation of the total process except the formation of the coating, can be used for process monitoring and quality control. |
