Popis:	The wetting behaviour of Ni–P braze alloys has been examined. In addition to detailed examinations of samples carried out after the wetting tests, real time observations of the wetting process have been made using a heating stage fitted to a light microscope. The work has concentrated on the Ni–11P (wt-%) eutectic braze alloy using laboratory produced Fe–Cr and Fe–Cr–Ni workpieces as well as commercial martensitic and austenitic steels and some nickel based alloys. The chromium content of the workpieces was found to dominate the spreading behaviour of the brazes. This is thought to be due to dissolution of the workpiece material and consequential dilution and complexing of phosphorus to increase the braze melting point. However, the behaviour of two commercial workpieces, Fecralloy and Hastelloy N, was anomalous.MST/1177
