Combined Heat Treatment and Coating Procedures as an Example of Plasma Assisted Processes

To improve surface properties as wear and/or corrosion resistance, thermomechanical surface treatments in glow discharge plasmas are already well known. These new technologies are environmentally friendly and therefore RUBIG PLASNIT plasmanitriding or PLASTIT PACVD-coating processes are the future surface treatments. The currently used industrial processes range from plasma-activation of component surfaces for following/additional treatments to diffusion and/or hard coating processes. By a combustion of diffusion and coating processes the hard coatings attain an appropriate supporting effect, improved layer bonding and reduction of cracking underneath the surface. The following overview illustrates the possibilities of plasma assisted processes.
