Abstract
Wetting of copper by three kinds of Ni-P based brazing alloys (NiP1O, NiCrl4P10 and NiNb1OP1O) was studied. All three alloys wet copper just after melting. Chromium and niobium improve wetting of copper relatively to the Ni-P braze. The interface between copper and brazing alloys in all cases is a solid solution of copper in Ni-P or Ni-Cr-P or Ni--Nb-P, either as a diffusion zone or as a homogeneous layer. Due to the interaction of copper and brazing alloys a Ni3P phase arises in each braze containing copper in NiP10, chromium in NiCrl4P10 and niobium in NiNb10P10, and a Ni based solid solution containing copper in each braze and chromium and niobium in NiCrl4P10 and NiNb10P10 brazing alloys, respectively.

Key words
Ni-P based brazing alloys, wetting, chromium, niobium
