Abstract

The method of autocatalytic reduction coating assures a precise reproduction of the coated surface. This is an advantage when the support surface has a complex geometry but also becomes a disadvantage because it requires a support without surface defects and without high roughness. Also the electroless method requires a special preparation of the support surface which should enhance its reactivity. This paper reveals the influence of different surface characteristics of the support on the quality of the coating. Metallographic analysis has been done on the surface and transversal section of Ni-P coatings of different steel surfaces.
