Описание (английский):

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.

Abstract

Overview

ISO 13826:2013 - "Metallic and other inorganic coatings - Determination of thermal diffusivity of thermally sprayed ceramic coatings by laser flash method" specifies a laser‑flash test method to measure the thermal diffusivity of self‑standing thermally sprayed ceramic coatings. The procedure applies to detached coating discs (typically 10 mm diameter) with thicknesses between 0.8 mm and 2 mm, and covers measurable diffusivity values from 10−7 m2/s to 10−4 m2/s over a temperature range of 300 K to 1500 K. Results are used with density and specific heat data to derive thermal conductivity for engineering design.

Key topics and technical requirements

Test principle: Apply a short, high‑intensity heat pulse to the front face and record the rear‑face temperature transient; determine the half‑rise time (t1/2) and compute thermal diffusivity.
Specimen: Thin circular discs, faces flat and parallel within 0.5% of thickness; coatings removed from substrate (methods described for separation).
Apparatus essentials:
- Uniform flash source (Nd glass laser preferred) with pulse FWHM
