This study includes the study of the effect of compressive pressure on the selected range (3,4,5) on the physical properties and X-ray attenuation of the compound (Al60%, Ni 10%, MgO 30%). (808nm) and 1Watt on the properties of this compound for different time periods (min (0,5,10,15,20). The effect of compressing pressure and time of surface treat...

... μ is the linear attenuation coefficient code known as the density of the unit area and its measurement unit is cm-1, Iº is the intensity of the elementary particles count / sec. Figure (4) shows the exponential decay curve as a result of obtaining a curve between the intensity of the window and the fish when changing the thickness of the absorbed substance. The X-ray machine fitted by the German company PHYWE was used for the purpose of measuring and calculating the X-ray attenuation coefficients using the voltage (35) (3), the attenuation coefficient was calculated and the mean free path, which represents the rate of distance traveled by radiation in the interceptor medium before the packet is removed, is measured in cm or gm / cm2 and is expressed mathematically by the following charge [15] . ...
