The name Champro was made up of the two words "chamber" and "process". It represents Sulzer Metco's thermal spray technology in a pressure chamber with a controlled environment. Different spray system types handle the process operating in a particular way. A part analysis for each type of spray system demonstrates the most economical customer solution. This paper discusses the processes involved in two types of thermal spray system for coating parts in a controlled atmosphere: type of system with continuous process and type of system with batch process. Paper includes a German-language abstract.
