| Abstract | ||
| This work presents an industrial unit for hardening and treatment of nano-materials and micrometers to improve their physical, chemical and mechanical properties by exposing them to laser radiation. The treatment process is carried out through the laser treatment industrial unit. It is composed of circular metal base with motor, rectangular holder, moving sides. The sample installation cavities which are metal joints that widen and shrink according to sample dimensions by incorporating the cavities vertically and moving the sides, the unit has black front and back barrier to prevent lasers with bottom cavity to store the black barrier. Scaling must be compatible with laser diameter or width; the unit has partition barriers and fixing arms to control the process. Laser and unit are operated to complete the treatment, method is physical process, the laser beam go through treated material without being absorbed or interact by transparent material, the treated nanomaterials or short fibres were collected. The samples were exposed to Nd -YAG third harmonic generation and Argon ion CW laser. The hardness was measured before and after laser irradiation. The current work will present an application on the hardening of E-fibre glass 731ED 1/32.The change in hardness were explained by raman spectroscopy. The research end with conclusions and recommendation for the expected application of the new treatment unit and method. | ||
