Laser surface texturing and micro-arc oxidation provide excellent approaches to enhance the adhesion strength and anti-corrosion performance of adhesive bonding interfaces in aluminum alloys, which can be applied in the field of automotive light weighting. Herein, micro-arc oxidation coatings were fabricated on the laser-textured aluminum surface under the voltage of 500 V for various treatment times (5 min, 15 min, 30 min, 60 min). The anti-corrosion performance of ceramic coatings on the laser-textured surface was analyzed using electrochemical measurements. The results of electrochemical measurement indicate that the coating on the sample surface presents two time constants corresponding to a dual-layer structure. The sample grown under 500 V for 60 min exhibits excellent protective performance with a value of 1.3 × 107 ohm·cm2. The adhesion strength of laser-textured ceramic coating is improved compared with the as-received substrate. The sample treated with 500 V for 30 min exhibits the highest bonding strength with a value of 52 MPa. The wider pores and bulges for the sample grown in 60 min would introduce microcracks and consequently reduce the adhesion strength.

“…The mass loss rates of 6% γ-Fe coating and 9% γ-Fe coating in 3.5 wt.% NaCl solutions are 0.17 and 0.12 mg•mm −2 •h −1 , respectively, after eroding for 1 h. This shows that the Febased composite coatings have better slurry erosion-corrosion resistance compared to the Fe-based coating (0.27 mg•mm −2 •h −1 ). It is very intriguing that the erosion mass loss of the coatings exhibits exactly the opposite tendency to the microhardness since the hardness has a significant impact on the slurry erosion resistance [20,43,44]. Consequently, it can be summarized that the hardness has a great impact on the erosion-corrosion resistance of the coatings.…”

“…The outcomes demonstrated that adding chromium might undoubtedly increase abrasion resistance. The composite with additional chromium had erosion wear resistance that was 1.44 times greater than the composite without chromium [20]. The effects of B 4 C, MoB, and TaB on the structure, phases, microhardness, and wear rate of Fe-based self-fusing alloy coatings were investigated by E et al The addition of the particles increased the hardness as well as the wear resistance of the coatings.…”

The Fe-based austenite-containing composite coatings with various contents (3 vol.%, 6 vol.%, 9 vol.%, 12 vol.%) of austenite powder additions were created by supersonic plasma spraying on 45 steel substrates. The microstructure, phase composition, microhardness, and porosity of the composite coatings were examed. Moreover, special attention was paid to the effect of austenite powder on the corrosion resistance of the austenite-containing composite coatings. The results found that the addition of austenite powders could significantly improve the corrosion resistance of Fe-based coatings, which is mainly due to three correlated phenomena caused by the austenite particles. First, austenite particles significantly reduce the porosity of the austenite-containing composite coatings and form a denser coating structure due to their low melting point and good chemical compatibility with the Fe-based alloy. Further, austenite particles help to refine the grains and increase the grain boundary density. Last but not least, austenite particles help to generate more diffusely distributed second phases in the coating, improving the chemical homogeneity and hardness of the coating.
