Low Nitrogen

Fe-N thin films have attracted considerable attention because they are potential candidates for magnetic recording with their large saturation magnetization and their good corrosion resistance1. It has even been demonstrated that saturation magnetization can be larger than the bulk iron one for low nitrogen contents2. The origin of the enhanced magnetic moment could occur from the metastable α″ Fe16N2 phase or from an expanded bcc FeN structure which is also called α FeN.

Milling Method

The magnetic and structural properties of FINEMET [Fe73.5Si13.5B9Nb3Cu1 wt %] amorphous powder were investigated after nitrification and mechanical milling. Fe-based amorphous powder were nitrified and crystallized simultaneously at 550°Cusing by ammonia(NH3) gas. Nitrified powder exhibited iron nitride phase such as γ′-Fe4N, Fe3N and α″-Fe16N2. Nitrified particles were more brittle than raw particles. As a result, nanometer sized nitride powder were fabricated by high energetic ball milling method. The saturation magnetization(Ms) and coercivity(Hc) of nitrified powder were increased due to nitride phase.

AbstractOrganically-modified silicate (Ormosil) films have been found to provide good corrosion resistance for metal substrates and are potential replacement systems for hexavalent chromiumbased conversion coatings. Significant enhancement in corrosion resistance properties were observed upon addition of sub-micron to micron-sized particles (TiO2, Al2O3, SiN, TiN) to the Ormosil coating as determined using accelerated salt spray and electrochemical analysis. Rcorr values derived from potentiodynamic polarization curves were found to increase from 1520 to (3800 - 4680) kΩcm2 upon addition of various concentrations of TiO2, Al2O3, SiN or TiN particles to the Ormosil thin film. Similarly, Epit values were found to range from +0.2 V for the non-doped Ormosil to (0.6 – 1.9) V for particle-doped Ormosil thin films.
