Due to the simple process, non-toxicity and environmentally-benign, silane treatment technology has shown a great potential in replacing toxic chromates in a variety of industries. The silane films provide excellent adhesion to the metal substrates and are a promising corrosion protection coating instead of the chromate conversion coating. The protection mechanism of silane film, the process of silane treatment and the research of film on different metals were summarized. The research shows that the linking between metal and silane film is mainly chemical bonding. In addition, the direct immersion method is the main method for the forming on the metal surface and the electrodepositing method is in the preliminary study stage. Besides, self-healing properties of silane films were mainly achieved through the addition of rare earth. According to the analysis of research, problem of silane treatment technology had been brought forward. Further, its aim of research in future was pointed out.
