For one thing, the book presents research aimed at obtaining thin phosphate layers that offer good corrosion protection of finished parts. The other aim was to develop techniques that result in coatings with good lubricating properties, as they are required in plastic deformation processing. Keywords: Thin Films Deposition, Phosphate Coatings, Surface-Active Agents, Zinc Phosphates, Degreasing, Lubricating Films, Corrosion Protective Films, Anticorrosive Phosphate Films, Phosphating Techniques, Plastic Deformation Processing, Phosphating of Iron-Based Metallic Parts, Thin Film Characterization, Optical Microscopy, Electronic Microscopy, EDX Analysis, XRD Analysis, Optical Profilometry, Corrosion Tests, FTIR Spectroscopy, Tribological Tests, SEM-EDX Analysis.
