Title: Pyrolytic carbon coating densities determn. - after all coatings applied, by determining micro-section properties using low energy X=rays
Inventor: HUSCHKA HANS DR
IPC: G01N23/04
Filed: 1977-12-21
Abstract: A method of determining the density of thin pyrolytic carbon coatings, which have been deposited in one or more layers on ceramic particles, esp. high temp. reactor fuel particles, consists of forming a microsection perpendicular to the plane of the coating and then determining the density of each individual layer, by comparison with reference specimens, by means of the absorption of low-energy X-rays. Pref. microsections 60-200 mu m thick are used with X-ray energies of 3-7 keV. The method enables the densities of individual coatings to be determined after all the coatings have been applied, and not merely the density of one coating after its application. In this way the effects of one coating on the density of the previous coating are taken into account.
