Abstract
Today, more than ever the greatest progresses are reached in the field of microprocessor technique. Electronic devices are becoming smaller and smaller and showing at the same time higher performance. This fact has an effect on equipment control in mechanical engineering. No equipment can be used economically without PLC and PC. Moreover, it is impossible to build one without using them. Since a long time electronic components like PLC are considerable reasonable in pricing compared to supposing simple mechanical or electro mechanical systems. At the same time higher recommendations are expected from operator and service persons. Thermal Spray guns and systems are in a steady further development. Beside the request for high power systems there is a demand coming up for smaller and more affordable systems. Nevertheless, high power plasma guns are also to be focused on due to the fact that there is still the demand for ceramic coatings on big components.
