“…Using the test protocols of STRESS-SPEC@FRM II instrument at GEMS, Gibmeier et al [54] studied local phase and residual strains for yttria stabilised zirconia (YSZ) thermal barrier coatings (TBC). The coatings were deposited using a mix of techniques (air plasma spray/APS; high velocity oxy-fuel/HVOF; vacuum plasma spray/VPS) on two different substrates (Inconel IN 738 LC, nickel-based superalloy/Mar M 247; 32 mm diameter and 3 mm thick).…”

Background During thermal spray coating, residual strain is formed within the coating and substrates due to thermo-mechanical processes and microstructural phase changes. Objective This paper provides a comprehensive guide to researchers planning to use neutron diffraction technique for thermal spray coatings, and reviews some of these studies. Methods ENGIN-X at the ISIS spallation source is a neutron diffractometer (time-of-flight) dedicated to materials science and engineering with high resolution testing. The focus is on the procedure of using ENGIN-X diffractometer for thermal spray coatings with a view that it can potentially be translated to other diffractometers. Results Number of studies involving neutron diffraction analysis in thermal spray coatings remain limited, partly due to limited number of such strain measurement facilities globally, and partly due to difficulty is applying neutron diffraction analysis to measure residual strain in the thermal spray coating microstructure. Conclusions This technique can provide a non-destructive through-thickness residual strain analysis in thermally sprayed components with a level of detail not normally achievable by other techniques. Neutron sources have been used to measure strains in thermal spray coatings, and here, we present examples where such coatings have been characterised at various neutron sources worldwide, to study residual strains and microstructures.

“…Using the test protocols of STRESS-SPEC@FRM II instrument at GEMS, Gibmeier et al [48] (as sprayed). It was proposed that it is almost impossible to provide unstressed reference material (due to thin layer of coatings) with identical microstructure to determine stress-free 𝑑 ℎ𝑘𝑙 0 .…”
