“…Particularities of materials with a heterogeneous structure of the surface layer foresee an interaction of soft matrix and solid phase in the process of elastic and plastic deformation. The matrix connects and holds the solid phase, therefore the alloy wear resistance depends on its mechanical properties [ 87 , 88 ]. If the matrix strength is insufficient, it is squeezed out (INDENTION) at stresses above the yield point of the matrix, due to the occurrence of a high level of plastic deformations in the plastic matrix.…”
