The book "Surface technology of aluminum and its alloys" describing the surface treatment, anodization and coloring of aluminum and its alloys. Aluminum alloys have many kinds of composition and it mean has been difficult to find a certain preplating procedure that will be equally satisfactory for all types and tempers of aluminum alloys, since the various alloys and products exhibit different metallurgical structures and different electrochemical behavior. Every alloy elements have different characteristic and structure that can effect to the behavior when treat with electroplating on aluminum metal. This book will be helpful for the students and researchers whoever doing research in the field of electrodeposition, anodization and coloring of aluminum and its alloys.
