Currently an alternative method of obtaining powder material for additive technologies from secondary raw materials (chips) by the grinding with the next plasma spheroidization is gaining popularity [9, 10].
This method of obtaining raw materials will significantly reduce the cost of products produced by additive technologies.
Materials and Methods The initial powder material obtained by the plasma spheroidization method was used for the laser cladding process [11].

Badawi* Physics Department, Faculty of Science, El-Minia University, Egypt *e-mail : emadbadawi@yahoo.com Keywords: Positron Annihilation Spectroscopy; Doppler broadening line-shape parameters; AlCu alloys; Trapping rate; Grain size Abstract Positron Annihilation Spectroscopy (PAS) is a powerful and versatile tool for the study of the microscopic structure of materials.
PAS is one of the sensitive non-destructive nuclear techniques used in material science.
Positron lifetime spectroscopy is based on the fact that positron annihilation is proportional to the electronic density at the annihilation site and so it can provide information about the electronic densities in materials.

The AlN piezoelectric thin film with crystal orientation (002) and crystal orientation (101) is deposited respectively by pulsed_DC sputtering on the different bottom electrode materials.
At the same time, that crystal orientation of AlN thin film depending on the different bottom electrode materials is pointed out.
