%X Cadmium presents excellent resistance to corrosion, being useful to form a protective coating mainly on iron but also on a variety of steels. A very common way to cover such substrates with Cd is by means of electrodeposition. However, more recently, the use of cadmium electroplating has been restricted due to environmental and health concerns. In addition, specific procedures must be taken afterwards to avoid hydrogen embrittlement on the surface of the coated materials. In order to take advantage of the corrosion properties of Cd and to eliminate the necessity of extra procedures after treatments, besides reducing the drastical risks of environmental contamination and health problems, a new process was developed which can be used for the Cd coating of the surface of metals using Plasma Based Ion Implantation and Deposition (PBII&D). In the process presented in this paper, cadmium is vaporized and ionized by means of an argon glow discharge, being implanted/deposited into/onto the surface of carbon steel H13 immersed in such plasma. X-ray analysis revealed the presence of new diffracted peaks for treated H13 samples due to implantation of cadmium. X-ray Photoelectron Spectroscopy (XPS) indicated 67 at.% of cadmium in the near surface and consistent depth profile. Scanning Electron Microscopy (SEM) images of the top treated surface indicated the absence of cracks, which is common in surfaces of steels coated by means of Cd plating. Prominent peaks of Cd were also identified by Energy Dispersive X-ray Spectroscopy (EDS). Finally, corrosion resistance evaluated by means of polarization curves showed the presence of very well pronounced passivated regions.
