Boronizing of commercial Ni-base heat-resistant alloys as Inconel 600, Inconel 625, Inconel 713C, Udiment 500 and Hastelloy B, has been investigated by means of a furnace heat treatment burrying in amorphous boron powder under an argon atmosphere at 1223K and 10.8Ks. The hardnesses of the boronized surface on the above alloys showed the range of Hv 1000 to 1600 depending on chemical compositions. Moreover, in order to investigate the effect of each alloying element in pure Ni on increase in boronized surface hardness, various Ni-binary alloys, which contained Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, Mn, Fe, Co, Al or Si elements up to 30%, were boronized. The boronized surface of the alloys has been investigated from metallographic and X-ray analyses and hardness distribution. Finally hardness estimation of boronized surface of commercial Ni-base alloys has been tried using the experimental results of hardenability of Ni-binary alloys.
