摘要：
The paper presents the results obtained on quick thermal shock tests performed on ceramic and metallic thermal barrier layers deposited on copper support. The ceramic layers were obtained by plasma jet metallic coating and the metallic ones by electric arc welding. Optical and scanning electron microscopy (SEM) investigations were also made on the ceramic and metallic samples, prior to all testing and after the quick thermal shock test. After testing and structural investigations, the two types of coatings were analyzed and compared as for the characteristics that confer them tire thermal barrier status.
