Substitution with more friendly elements

What is it about?

As described in detail already, environmentally friendly surface finishing processes are available by substituting the original process or plating itself with something less harmful. As for the process changes, we described the details and gave examples in chapter “Process Changes”. In that chapter, we mainly mentioned physical vapor deposition(PVD). On the other hand, we focused on the substitution of plating materials from aqueous solutions. As concrete examples,we talked about some aqueous processes for the substitution of hexavalent chromium plating. This chapter mainly describes alloy plating processes, trivalent chromium processes and composite plating.

Why is it important?

There are many possibilities to replace the conventional methods with more user-friendly processes. In this chapter, we stressed some possibilities for the surface finishing processes from aqueous plating. The examples include some of my research results.
