文摘

Zirconia coatings on copper prepared by the low-pressure plasma spraying of a ZrO₂ + 5% Y₂O₃ powder through a mesh mask exhibit high resistance and low thermal conductivity in tests in the nitrogen plasma stream of a plasmatron. Data on the coating structure and its changes during thermal testing derived by scanning electron microscopy, X-ray diffraction analysis, and nuclear backscattering spectrometry are discussed.
