The grain sizes of both phases are in the nanometric range, indicating that the obtained composite has nanocrystalline structure.

Introduction IOT (Internet of things) concept is put forward in 1999 by the Auto-ID Labs at MIT proposed that the current definition of things there is no uniform standard, widely accepted concept of networking is through various information-aware devices, such as sensors, RFID technology and other various devices and technologies, real-time acquisition of any need to monitor, connected, interactive objects or processes, collecting their sound, light, heat, electricity, mechanics, chemistry, biology, location, etc [1]. a variety of information which is needed.
At present, the development of IOT is in the initial stage, more often, it is just a content of technology and its specific implementation structure is still under conducting.

It is very complex for the anodic film forming process, including many factors such as physics, chemistry, and electrochemistry.
The buffer layer can decreases the dissolution behavior on the anodic film, increasing the film forming rate, improving the microcellular structure of the oxidation film.
