This new surface treatment is simple and easy as well as low in cost. The processes can even be performed by hand. Pharmaceutical raw materials used for the surface treatment, such as hydrochloric acid and nitric acid used in a mixed acid washing process and vegetable oil used in an organic film forming process, are easily obtained in many countries.

Effects of the surface-treated A5052 aluminum alloy on the adhesiveness of joining dissimilar materials, such as A5052 aluminum alloy sheet and polyamide resin sheet, was examined to manufacture a multi-material. Various surface treatments for the A5052 sheet were performed. The hot melt adhesive sheet comprising polyamide resin was used as the adhesive. The shear strength of adhered specimens was measured via tensile testing, and the shear strength was made to be the joining strength. Using various surface treatment techniques, oxidation films with different hole sizes and surface roughness were formed on the A5052 aluminum sheets. The joining strength of the surface-treated specimens was the lowest, whereas those joined via anode electrolysis exhibited the highest joining strength. These differences in joining strengths were owing to the anchor effect and chemical interfacial bonding force.

The corrosion of steels has long been the topic for materials scientists. It is established that surface treatment is an efficient way to improve the corrosion resistance of steels without changing the bulk properties and with low costs. In the present paper, different kinds of surface treatment techniques for steels are briefly reviewed. In particular, the surface modification involving nanostructure formations of steels by using a low energy high pulsed electron beam (LEHCPEB) treatment is lightened in the case of an AISI 316L stainless steel and D2 steel. The overall results demonstrate the high potential of the LEHCPEB technique for improving the corrosion performance of steels.
