Sessile drop spreading tests have been carried out to evaluate the influence of braze and substrate chromium content on the wetting and flow of Ni–Cr–Si–B and Ni–Cr–P brazes on nickel and Ni–Cr substrates. The effect of filler metal chromium additions is examined in terms of fluidity processes, while the role of base metal chromium content is discussed in the context of oxide reduction and alloying phenomena.
