Abstract

1,126,001. Photo-electric coating thickness control. UNITED STATES STEEL CORP. Dec. 31, 1965 [Jan. 6, 1965], No. 55497/65. Heading G1A. [Also in Division H1] The density of a vapour in a vapour-coating machine is measured in order to control the coating thickness, by subjecting the vapour to a high energy beam, e. g. of electrons, in order to produce characteristic X-rays, a portion of which is detected and measured. The particular application is in the continuous coating,of strip material and is suitable for thickness control in the vacuum coating of steel strip with aluminium. In one arrangement, Fig. 1, an electron beam 2 from a gun 1 is bent in a semicircular arc by a magnetic field to heat and melt the coating material 3 in a crucible 4. The resulting vapour flows towards the strip 6 to be coated. The electron beam 2 comes into contact with atoms of the coating vapour producing characteristic X-rays 8. Some of these enter the collimator 9a of a detector 9, the output of which is amplified, and counted, allowing for scattered radiation. In another arrangement, Fig. 2 (not shown) separate means produce the coating vapour which flows through a housing (10), an electron beam being directed at right angles to the flow of the vapour. Characteristic X-radiation emitted in a direction mutually at right angles to the electron beam and vapour flow, is investigated by the collimatordetector system.
