DEFINITION

Classification: 445/58

With coating, e.g., providing protective coating on sensitive area:

(under subclass 1) Method for treating the surface of a workpiece so as to form a film or surface layer of material

thereupon.

(1) Note. The coating material may be the same or different composition from the base material.
