摘要：
Surface hardening of gold containing Ti, Zr, Hf, V, Nb, Ta, Cr, Mn, Fe, Co or Ni was tried by means of boronizing technique with powder boron under argon atmospheric furnace at 900 to 950 degree C for 6 hrs. The obvious surface hardening was possible for the gold alloy which contains more than 5%Ti, 5%V, 3%Cr, 15%Mn, 10%Fe, 5%Co or 5%Ni. Surface hardness and thickness of the hardened layer strongly depended on the alloying element added. The phases formed on the hardened surface were investigated by X-ray diffraction analysis.
