The tradition surface treatment techniques include electroplating and organic coating, etc. However, they can no longer satisfy the stringent requirements of modern designs. Recently the rise of plasma technology and nano-materials provides a feasible approach for the surface modification of components. The objective of the present development program is to prepare a homogenous, dense and transparent coating to protect the watch surfaces by means of a new vapor deposition technique. As a result, the surface hardness can be superior to that of sapphire, which will improve substantially the wear resistance and endurance of watch surfaces. In addition, the coating can prevent the surface corrosion caused by some external factors such as climatic change, sea water and sweating, thus keeping the original brightness and luster, or even making the appearance more elegant and upscale. In this study, a pilot facility for thin film deposition will be set up, and the coating processes as well as the structure and properties of the deposited thin films will be studied in details. Based on this, we’ll provide the technical service for the watch industry. Meanwhile, we’ll hold seminars/workshops to promote the new watch products with the protective coatings as well as their superior properties.
