We investigated highly (100)-oriented PZT films directly grown on Pt films coated on RuO2/SiO2/Si substrates via sputtering method. By controlling the preferred (100) orientation volume of the Pt films, we confirmed the effectiveness of high (100) orientation of Pt films suitable for the growth of highly (100)-oriented PZT films.

The 2-methyl-4-nitroaniline (NA) was converted into the raw material N-benzyl-2-methyl-4-nitroaniline (BNA), and the solubility of BNA in various organic solvents was calculated gravimetrically. BNA’s solubility and crystal structure make it an excellent solvent for the low-temperature solution growth method used to create single crystals of BNA with orthorhombic structure studied through single crystal analysis.

The obtained results showed that the coating at the spray current of 300 A, the air pressure of 5.5 bar and the stand-off distance of 162.8 mm has the lowest porosity and highest microhardness. In addition, this coating also has better adhesion to the steel substrate and wear resistance than other coatings. Moreover, X–ray phase analysis showed that the following phases are created on the surface of the Al-Mg coatings: Al, Al2MgO4 and Al3Mg2.
