A novel aromatic ether diamine 1,3-bis(4-aminophenoxy)benzene (TPER) was synthesized. Four kinds of polyimides were prepared with obtained TPER, 4,4’-diaminodiphenyl(ODA), pyromellitic dianhydride (PMDA) and end capped with phthalic anhydride(PA). The imidization process was solution imidization followed by solid-phase thermal imidization. The results of DSC, 1H-NMR and FTIR analysis showed that high purity TPER had been successfully synthesized. FTIR spectras of polyimides indicated the imidization process could reduce the final imidization temperature. The inherent viscosities([η]) showed molecular weight could be controlled via the introduction of flexible diamine and end capping agent. And all polyimides exhibited excellent thermal stability.

The synthesis and characterization of Ti and TiN thin films of different thicknesses was carried out on a martensitic stainless steel AISI 410 substrate used for tool manufacturing. The mechanical parameters between the interacting surfaces such as thickness, adhesion and hardness were measured. By means of the scanning electron microscope (SEM) the superficial morphology of the Ti/TiN interface was observed, finding that the growth was of columnar grains and by means of EDAX the existence of titanium was verified.  Using X-ray diffraction (XRD) it was possible to observe the presence of residual stresses (~ -3.1 GPa) due to the different crystalline phases in the coating. Under X-ray photoemission spectroscopy (XPS) it was possible to observe the molecular chemical composition of the coating surface, being Ti-N, Ti-N-O and Ti-O the predominant ones.
