On-Line-Monitoring Control of Stainless Steel Coatings Obtained by APS Processes

A number of experiments were carried out to optimize the thermal spraying of stainless steel using online monitoring. The experiments were designed to determine the influence of spraying conditions on in-flight particle behavior and layer properties. By measuring the speed, temperature, and spatial distribution of the particle stream, the monitoring system made it possible to optimize spray parameters and thus produce stainless steel layers with tailor-made properties. Paper includes a German-language abstract.
