The experiment is based on novel magnetic filtered cathodic vacuum arc (FCVA) technology, the effects of the structure and C contents of TiAlCN/TiAlN/TiAl composite coating on anticorrosion and wear resistance were studied. The macro/micro properties of the coatings were systematically characterized by SEM, XRD, XPS, electrochemical tests and friction equipment. The results show that, with the increase of C content,the form of C element in the coatings transforms from the TiAlCN solid solution to the coexistence of crystallized TiAlCN/amorphous carbon. The TiAlCN/TiAlN/TiAl coating with TiAlCNcrystallized/amorphous carbon nanocomposite structure demonstrated excellent performanceby combining the advantages of each layer, which the hardness reaches an ultrahigh leveland the amorphous carbonwith excellent self-lubricating effect exists in the coating structure. In 3.5% NaCl electrochemical corrosion test, Ecorr increased by 5.6 times to 0.271 V, Icorr decreased by 1/52 to 8.092 ×10–9 A·cm–2. During the dry sliding, friction coefficient decreased by 1/3 to 0.43, and wear rate decreased by 1/1.4 to 1.13×10–5 mm3·N–1·m–1.
