2.1. Preparation of the MCC
The ENP coating was fabricated on substrate of mild carbon steel, which was cut into the size of 0.5 mm × 50 mm × 20 mm. The detailed procedures for electroless deposition ENP coating were listed in Table 1. The composition and working conditions of the used electroless bath were shown in Table 2.
