Abstract

The feasibility of hardfacing of silver alloy with boronizing technique using pure boron powder was investigated. As a favorable alloying element to have a good affinity with boron and good solubility in silver, only manganese was selected to satisfy the above condition among IVa, Va, VIa, VIIa and VIII group metals in the Periodic Table. Surface hardening with boronizing technique was possible for Ag-5, 10, 15, 20 and 25%Mn alloys, and maximum hardness and thickness of hardened zone were Hν 700 to 1200 and 15 to 35μm at the treating temperature of 1173K for 21.6ks. These hardened zones composed of the outer MnB boride phase and inner Mn_2B boride phase. Moreover the spiky Mn_2B phase had a strong coalescence with substrate base metal.
