Neutron diffraction residual strain measurements in nanostructured hydroxyapatite coatings for orthopaedic implants

► Texturing in hydroxyapatite coatings. ► Residual stress dependency on orientation of planes. ► Tensile residual stress on (030) & (211) planes. ► Compressive residual stress on (022) & (213) planes. ► Neutron diffraction through-thickness strain measurements.
