Abstract
The quaternary alloy (Co/Ni/P/Mn) coatings were prepared using electroless plating on the polypropylene. Compositions of the quaternary alloys (Co/Ni/P/Mn) were controlled by the amount of agents. The composition by EDS, morphology with SEM, film thickness, and surface electrical resistance of the samples were measured. Higher phosphorous content samples give larger electric resistance, thus a relationship is admitted between P content and electric resistance. The corrosivity of the coatings were evaluated by electrochemical methods in the 3.5 wt% NaCl and 5.0 wt% $H_2SO_4$ solutions, respectively. It was concluded that phosphorous addition enhances resistivity in the corrosion.
