“…It can be observed from Figure 12 that the ratio of H 3 /E 2 initially increases and then decreases as the working voltage increases, which is consistent with the elastic recovery rate trend. The ratio of H 3 /E 2 reaches its highest value of 0.049 at a working voltage of 12 V, indicating the best resistance to plastic deformation [ 45 ].…”

An innovative brush plating process for preparing coatings on the inner wall of metal pipes is proposed, which aims to solve the limitations of current electroplating technology and improve the performance of the inner walls of metal pipes. While optimizing the process, the effect of working voltage on the microhardness, thickness, surface morphology, corrosion resistance, and elastoplasticity of the Ni coating on the inner wall of the tube was studied under the new process. The results indicate this technique can produce high-quality coatings on the inner wall of pipes in a simple and efficient manner. As the working voltage increases, the surface quality and comprehensive performance of the coating show an increasing trend followed by a decreasing trend. At 12 V, the coating exhibits the highest surface density and uniformity, the lowest surface roughness, the best corrosion resistance, and the maximum microhardness of 575.8 HV, with a corrosion current density of 1.040 × 10−5 A·cm−2, a corrosion rate of 0.122 mm·a−1, the maximum elastic recovery ratio he/hmax of 0.36, and the best deformation resistance. This study demonstrated the effectiveness of this method in improving the durability and functionality of metal pipes and its potential for various industrial applications.

“…To better investigate the effect of TiC on composite coatings, Ni−P−TiC was prepared by Shahzad et al 15 It was found that the addition of TiC to Ni−P coatings improved the hardness, wear resistance, and corrosion resistance of the coatings. Li et al 16 Meanwhile, in order to deal with the rapid development of society and the strict requirements put forward by the industrial field, 17 these days, the majority of researchers opt to heat-treat composite coatings to increase their hardness, wear resistance, and corrosion resistance in addition to using nanomaterials as additions to boost metal alloy coatings' overall performance. 18−20 found that the addition of SiC nanoparticles and heat treatment were the two commonly used methods to increase the hardness of Ni−P, 21 and by these two methods, the hardness and wear resistance were substantially improved.…”

Li et al created a composite Ni–P–(sol) Al 2 O 3 coating by electrodeposition on the surface of Q235 steel. It was found that the Al 2 O 3 sol could effectively improve the coating structure and refine the grains of the Ni–P alloy and had a certain improvement in the hardness and corrosion resistance of the coating.…”

This study describes the preparation of Ni−P− Cr 3 C 2 composite coatings using pulsed electrodeposition, with varying Cr 3 C 2 concentrations (0, 1, 2, 3, 4, and 5 g/L). Subsequently, the Ni−P−Cr 3 C 2 composite coatings are heattreated at different temperatures (200, 400, and 600 °C) using the characteristic of Cr 3 C 2 oxidizing to Cr 2 O 3 at high temperatures. The Ni−P coatings, Ni−P−Cr 3 C 2 composite coatings, and heattreated-state Ni−P−Cr 3 C 2 composite coatings are compared and discussed. The results show that the hardness, wear resistance, and corrosion resistance of the composite coatings are optimized when the Cr 3 C 2 content is 3 g/L and the heat-treatment temperature is 400 °C. This is due to the presence of oxides such as Cr 2 O 3 on the surface of the composite coatings after heat treatment at 400 °C. By efficiently enhancing the coating's densification to the substrate, these oxides raise the composite coating's resistance to corrosion and wear. The Ni−P−Cr 3 C 2 composite coating in its heat-treated makeup at 400 °C is found to have long-term corrosion resistance in the 3.5 wt % NaCl solution immersion test. This study provides a new idea in the field of corrosion.
