Abstract
- • The Fe-Cr-Ni based composite coating was prepared using laser cladding method. • The addition of rare earth elements makes the cladding layer more dense and more refined. • Increased tensile strength, increased yield strength and increased impact value. Laser cladding technology was used to prepare Fe314 coating with added CeO 2 and La 2 O 3 on the surface of EA4T steel. The microstructure and structure of the coating were analyzed using scanning electron microscopy, electron probe microanalyzer, and X-ray diffraction. The mechanical properties of the coating were tested using a microhardness tester, universal testing machine, and pendulum impact testing machine. The results show that the addition of rare earth elements makes the cladding layer more dense and more refined; at the same time, compared to the base material, the tensile strength of the repaired specimen increased by 12.9 %, the yield strength increased by 23.3 %, and the impact value increased by 43.6 %.
