basic information
【Purpose of the Course】 All physical properties of plating films originate from the structure of the plating film (metallurgical structure, grain size, surface morphology, orientation, film stress, adhesion, etc.). Therefore, by controlling the structure of the plating film, most physical properties of the plating film can be arbitrarily controlled. In plating technology, the process of atoms precipitating from ions in solution is explained electrochemically, but the plating film itself is a metallic material. Thus, the structure of the plating film can be explained and controlled by metallurgy. In particular, the theory of adhesion of plating films is unique to the speaker, and it is believed to be the ultimate absolute theory. Additionally, this lecture will explain a completely different theory regarding the corrosion of metals than what has been presented so far.
