ISO/NP 20010.2

Metallic and other inorganic coatings- Determination of volume fraction of monoclinic phase in yttria stabilized zirconia of thermal barrier coatings by X-ray diffractometry

Scope

This International Standard specifies a method for determining the volume fraction of the monoclinic phase in yttria stabilized zirconia (YSZ) of thermal barrier coatings (TBCs) produced by thermal spraying, using X-ray diffractometry, in order to evaluate the degree of degradation of TBCs used at high temperatures.
