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.

“…[3][4][5] The processing of TiAl alloys is highly constrained due to its weak ductility at room temperature, and its development and usage are also limited due to its long manufacturing cycle. [6] Recent advances and ongoing developments in additive technology have coincided with its increasing deployment in manufacturing, [7] and it has emerged as an ideal process for manufacturing titanium-aluminum alloys. [8] However, high manufacturing costs have greatly restricted the development of powder additive manufacturing (AM).…”

Herein, the deposition of a Ti–Al(48 at%) alloy via twin‐wire arc additive manufacturing (WAAM) using plasma arc welding (PAW) and tungsten inert gas (TIG) welding arc sources is presented. The microstructure and the phase composition of different regions of the alloy are analyzed using metalloscopy and X‐ray diffraction. The transient temperature field and residual stress distribution are measured before and after the process, respectively. A transient thermostress model is established using the finite‐element method. Results show that the alloy is composed primarily of α2‐Ti3Al and γ‐TiAl phases, while the microstructure evolution during the Ti–Al(48 at%) alloy deposition process is described. The thermal conductivity in the lower region of the alloy far exceeds that in the middle and upper regions. The thermal conductivity is smaller in the upper region and the midregion, resulting in the increase in heat accumulation. Due to arc shrinkage and reduced heat input, the PAW process reduces the heat accumulation and stress distribution differences more effectively than the TIG process.

Several innovative mixed powders of Ti6Al4V and NiCr-Cr3C2 with different CeO2 contents (0, 1, 2, 3, and 4 wt.%) were designed, and Ti2C-reinforced CrTi4-based composite coatings were prepared on the Ti6Al4V surface via laser cladding technology. The effects of CeO2 amount on the forming quality, microstructure, hardness, and wear resistance of the composite coatings were studied. The results showed that the CeO2 amount had a significant influence on the forming quality of the composite coatings. The cracks were eliminated completely when the CeO2 content was 2 wt.%; furthermore, the lowest porosity was obtained with the addition of 3 wt.% CeO2. The primary phase constituents of the coatings were non-stoichiometric Ti2C and a β-type solid solution (CrTi4) as the reinforcement and matrix, respectively. CeO2 and a low quantity of Ce2O3 were re-precipitated at the Ti2C/CrTi4 interface and CrTi4 grain boundary in the coatings with CeO2 addition. In addition, the average hardness of the composite coatings was 1.28–1.34 times higher than that of the Ti6Al4V substrate. The wear resistance of the composite coatings was significantly higher than that of the substrate. However, both the composite coatings and the Ti6Al4V substrate exhibited a mixed-wear mode, i.e., abrasive and adhesive wear.
