Description
Summary:The purpose of this letter is to describe observations obtained by x-ray imaging of the crack propagation, posority, residual strain and mass distribution of laser post-treated plasma sprayed zirconia coating. The test samples were prepared by plasma spryaing approx0.4 mm thick commercially pure zirconia on a 3 mm thick Al6061 aluminium alloy sheet and then laser remelting the coating using an Nd-YAG laser. X-ray imaging is found to provide a non-destructive means to characterize surface coatings such as plasma sprayed coaitngs. It was found to be effective in acquiring simultaneously data on internal cracking, residual stress, porosity and mass distribution in the coating.
