This paper discribes the thickness determination of magnetic layer on aluminum disc packs using
238
Pu excited fluorescence X-rays of Fe. The method is rapid
nondestructive and highly precise. The principle of measurement
design of detection device
elimination of interference factors and data treatment are discussed. The range of thickness measurement is 0.5—15µm. The precision of the thickness measurement is better than 5% when thickness of coating is over 1µm.
