摘要：
A usual practice during zinc hot-dip galvanizing is the addition of nickel in the liquid zinc which is used to inhibit the Sandelin effect. Its action is due to the fact that the zeta (zeta) phase of the Fe-Zn system is replaced by the T (tau) phase of the Fe-Zn-Ni system. In the present work an attempt is made to explain the formation of the T phase with thermodynamics. For this reason the Gibbs free energy changes for T and ( phases were calculated. The excess free energy for the system was calculated with the Redlich-Kister polyonyme. From this calculation it was deduced that the Gibbs energy change for the tau phase is negative. As a result its formation is spontaneous.
