Cr, Ni, Co, and Zn loading amounts were diluted inside the matrix using rates varying from 0 wt% to 16 wt% in order to study the impact of loading elements on glass characteristics. By using XRD and SEM, it was determined how loading factors affected the structural and morphological characteristics of glass thin layers.

This paper deals with scanning electron microscopy (SEM) examination and the wetting behavior of the phosphate glass-metal powder composites. We focused on the filler effect on wetting characteristics, such as interfacial free energy.

Hence, within this work we have studied the electrochemical behaviour of different zones of the welded steel 316 in 1 M HCl media. The macrography study of the welded steel has revealed the different areas with a good contrast.
