Abstract:
A method for producing a thermal barrier coating for a component of an internal-combustion engine, the component being exposed to hot gases, the thermal barrier coating having a columnar structure, comprising the steps of:providing acetylacetonates of zirconium and at least one stabilizing element selected from the group consisting of alkaline earth metals and rare earths as starting substances; vaporizing the starting substances by heating to at most 250Â° C. so as to form coating gases; transporting the coating gases in an admission system that has been heated to at most 250Â° C. to the component; and depositing the thermal barrier coating having a layer thickness between 25 &mgr;m and 1000 &mgr;m by heating a surface of the component to be coated at a deposition temperature between 300Â° C. and 1100Â° C. at a process pressure of between 0.5 mbar and 50 mbar so that the coating gases are broken down.
