The Comparative Analysis of the Fe–Cr–C–Ti–Al Coatings Synthesized by Laser, Arc and Hybrid Cladding Methods

The Fe–Cr–C–Ti–Al cored wire layers were cladded by laser, arc and hybrid methods. Mechanical tests have shown that the cladded layers strongly differ in wear resistance. The metallographic, X-ray diffraction and durometric studies were carried out to identify the reasons of such difference. The analysis of the study results showed that the main reason is the difference between the cooling rates of the cladded metal in the region of 1100–800 K. This difference provides the formation of the metastable austenitic structure, which significantly impacts the wear resistance of the cladded coatings.
