Abstract
The paper presents in brief the technological parameters used for plasma spray deposition. It is also describe the hanging layer deposition (100% metal) with the HVOF device and the other layers deposition in argon-hydrogen atmosphere using plasma jet generated by a METCO7M device. There are analyzed microscopy images performed on deposits of thermal ceramic barriers at Diesel engine pistons.
Key words:plasma jet; deposited layer; BARRIERS; hanging layer
