Abstract

There are many types of methods in measuring the coating thickness. One of the methods is by using Beta Thickness Gauging method. The purpose of this study is to determine the thickness of cutting tool coating by using the beta (β) backscattering gauging technique. The intensity of the backscattered beta particle radiations of Srontium-90 (Sr-90) and Cobalt-60 (Co-60) is related to the thickness of material coating on the base material of cutting tool. With a fixed measuring geometry, the radioactive sources and base material, the intensity of backscattered beta particle is dependent on the coating thickness. The results were compared with the methods and sources of thickness measurement. There are several parameters that involved in this measuring process, such as thickness, angle of source holder and source detector over the surface, distance between specimen and source, and other. Value of cutting tool coating thickness is measured by using GM (Geiger-Müller) counter instrument that can detect a single particle of ionizing radiation, and also by using backscattering technique.
