✦ Synopsis


Steady state polarization of Cr, Mn and MO were measured in liquid ammonia with NH,NO, and NH,CI at 0Β°C and 20Β°C. Cr and MO can corrode in the active and passive states. Mn remains active, but a porous film is deposited after prolonged dissolution. From the Tafel slopes it is concluded that the metals are oxidized to divalent ions during active dissolution.

High chromium martensitic steels are designed to provide high corrosion resistance in combination with high strength. Some of these steel grades contain primary carbides for improving the wear resistance, e.g. the steel 440C. The present paper mainly deals with the effect of chemical composition and
