The standard "GB/T 31568-2015 Thermal spray Thermal barrier ZrO 2O coatings Determination of grain size, Scherrer formula method" specifies a method for determining the grain size in thermal spray ZrO 2O coatings by X-Rays diffraction method. The Scherrer formula allows accurate measurement of the cubic, tetragonal and monoclinic ZrO 2O grain size in thermal barrier coatings in the range of 2 nm to 100 nm. The standard describes in detail the measurement principles, test conditions and calculation steps for specimens without internal uneven strain. The determination of grain size helps to evaluate the performance and stability of coatings, ensuring their effectiveness in high temperature environments.
