FIELD: heating.
SUBSTANCE: coating consist of zirconium oxide, yttrium oxide and aluminium oxide with the following components ratio, wt %: Al2O3 - 1-8, Y2O3 - 7-9, ZrO2 - other.
EFFECT: expansion of the ceramic thermal insulation coating application range, due to using in it the widely available material - aluminium, oxide of which is chemically more stable.
