What is it about?
As described in detail already, environmental friendliness is needed for sustainable development. There are two basic ways to make the surface finishing process more environmentally friendly. One of them is the substitution of hazardous materials with harmless substances. The other one is the utilization of a closed system for surface finishing/coating. From the viewpoint, physical vapor deposition (PVD) and chemical vapor deposition (CVD) seem to be the most favorable processes, since both have already been established. In this chapter, we describe both processes and discuss the effectiveness and possibility of changes from the conventional plating process to a dry process.

Why is it important?
In this chapter, I stressed the importance of the determination to change the conventional process to the new one. The way of change can be classified into two types. One of them is the invention of completed new processes and the other one the closed system such as PVD, CVD etc. And concrete examples were mentioned.
Perspectives
When you come to think about the process change, company persons may hesitate it from the financial viewpoint. However, the change to the environmental friendliness must be inevitable. The decision must be needed for the long term. I would say that it would lead also to the development and innovation.
