METHOD FOR THERMALLY COATING SURFACES

摘要

1. A process for the thermal coating of surfaces of work-pieces (1) with a jet (3) comprising a heated gas and a liquefied material whilst simultaneously cooling the surfaces with a cooling jet (6) which contains carbon dioxide and is produced in a nozzle (7), the carbon dioxide being supplied to the nozzle opening in liquid form, characterized in that a further medium having a lower molecular weight than carbon dioxide is admixed with the carbon dioxide prior to or at the time of its exit from the nozzle opening.
