Many kinds of NDT systems [1-3] utilize an eddy current (EC) method to detect and evaluate defects in high conductivity materials.
The proposed eddy current system can be also utilized to analyze low conductivity materials or such materials containing small metal particles [4].
A magnetic flux generated by an excitation coil induces eddy currents in the tested material.

However, the process is accompanied by a lot of difficulties [5, 6, 17], and low score resistance of materials should be mentioned first of all.
The objective of the study was to investigate the surface layers in the titanium and aluminum alloys, analyze the score resistance of the above materials coated, and evaluate the coating efficiency in the production process.

Introduction Carbon fibers were used as reinforced materials in the aluminum matrix composites due to its low density, high strength, and high modulus [1, 2].
Because of the lack of wetting of the carbon fiber with the molten aluminum and the formation of brittle materials between the carbon fiber and the matrix at high temperatures [3, 4], the surface of carbon fiber need be modified to solve the compatibility between carbon fibers and matrix material.
Then, the carbon fibers were put into 10%NaOH solution to neutralize the remnant acidulating solution on carbon fibers surface, avoiding its bad influencing on pretreatment. 5g/L carbon fiber was dipped into neutralizing solution at 25℃ for 3~5 min. 1μm Fig. 1 The appearance of carbon fiber surface after burning and acidulating Adsorbing easy oxygenation materials on the carbon fibers can be sensitive surface.
