An electrochemical study of the corrosion resistance of boride coating obtained by thermo-reactive diffusion
The corrosion resistance of three special steels improved by thermo-reactive diffusion (TRD) was investigated. Samples prepared from the test materials were treated at graphite crucible bath where borax, boric acid and ferro-silicon were mixed. The coating process was done at 1220 K for 6 h. The cor...

| description | The corrosion resistance of three special steels improved by thermo-reactive diffusion (TRD) was investigated. Samples prepared from the test materials were treated at graphite crucible bath where borax, boric acid and ferro-silicon were mixed. The coating process was done at 1220
K for 6
h. The corrosion resistance of the borided samples was evaluated by the Tafel polarisation and electrochemical impedance spectroscopy (EIS). The results show that the boronizing process can improve the corrosion resistance of the steels. Also, coating porosity with exposure time has been determined using the corrosion potential difference between substrate and coating, and polarisation resistance,
