“…The phase composition determined by means of XRD analysis consists, in both cases, of γ-Ni/Ni 3 B solid solution and further phases like CrB and Cr 6 Ni 16 Si 7 . Similar γ-Ni/Ni 3 B phases were already previously reported in the literature [21][22][23]. Corroborating the XRD with the EDX spot analysis, the matrix marked with A in Figure 5a,b consists of the γ-Ni/Ni 3 B phase, the darker region marked with B shows the primary crystals of CrB, while the lighter region of C represents the Cr 6 Ni 16 Si 7 .…”

“…The behaviours of micro-hardness show evidence of a relatively high dispersion of micro-hardness values, especially in the materials with a higher carbon and chromium content. In these materials, hard particles of carbides and borides [19], which were probably the cause of increased micro-hardness values to more than 1000 HV0.1, occur with a higher probability. In all cases, a clear interface between deposited layers and base material was recorded.…”

“…6. It can be stated that microstructure typical for this type of materials was reached in all cases after solidification [19,20,22,23,24]. It is a mixture of γ-Ni solid solution and several intermediate phases, especially of chromium boride CrB, boron nitrides Ni 3 B and Ni 4 B 3 , and nickel silicide Ni 5 Si 2 .…”
