Influence of laser power on microstructure control and performance of Fe-based coatings for surface strengthening of coal mining equipment
Source abstract
Abstract
Abstract To improve the surface performance and service life of key components of coal mining machinery, high-performance Fe-based alloy coatings were deposited on AISI 1020 low-carbon steel by laser cladding. The effects of laser power on the microstructure, corrosion resistance and frictional behavior of the coating were systematically explored, providing a theoretical basis for its engineering application in the field of coal mine machinery repair and remanufacturing. The results show that, the regulation of laser power significantly affects the crystal structure and stress state of the coating. XRD and microstructure analysis reveal that the grains change from fine and dense to coarse and irregular, Si is segregated within the grains, and Cr and C are prone to enrich at the grain boundaries. And excessively high power leads to coarsening of the structure and weakening of the interface. Samples S1–S3 exhibit the optimal hardness, mainly due to grain refinement, precipitation strengthening, and solid-solution strengthening. The coating prepared at 1500 W exhibits the best corrosion resistance, benefiting from the combined effect of a dense passivation film and a fine-grained structure. Tribological tests showed that the coatings improved the friction and wear performance of the substrate, with S1 exhibiting the best friction stability and wear resistance.
