Abstract

ISO 13826:2013 specifies a test method of thermal diffusivity of thermally sprayed ceramic coatings using laser technology.

This test method is applicable to self-standing thermally sprayed ceramic coatings of thickness between 0,8 mm to 2 mm, deposited by various thermal spray processes and removed from the substrate. Thermal diffusivity values ranging from 10⁻⁷ m²/s to 10⁻⁴ m²/s are measurable by this test method for temperature range from 300 K to 1500 K.
