Abstract

The peculiarities of wetting and contact interaction in the NiAl―CrB 2 system were studied. It has been investigated that during the wetting the drop is completely spread out on the surface with formation of zero contact angles. The phases and chemical composition of the interaction products in the studied system was determined. On NiAl―CrB 2 system the formation of additional strengthening boride phase Ni―Cr―B was identified.
