<p>High-temperature waste incineration power plants (WIPPs) expose boiler tubes, superheaters and grates to aggressive combinations of chlorine-rich flue gases, molten-salt deposits and erosive ash. These conditions rapidly degrade conventional steels. Laser cladding offers a way to fabricate dense, metallurgically bonded coatings by melting powder or wire feedstock with a focused laser. This review summarizes recent advances in laser-clad corrosion-resistant coatings for waste incineration power plants, focusing on Ni-based, Fe-based and multi-component alloys. Ni-based alloys, such as Inconel&#xa0;625, provide high tensile strength and good high-temperature corrosion resistance; however, their cost and susceptibility to solidification cracking remain challenges. Fe-based and Co-based coatings are more economical, but they require alloying with Cr, Mo, or hard particles to withstand chloride-containing slags. High-entropy and amorphous alloys offer promising combinations of corrosion and wear resistance. The review compiles experimental data on laser power, scanning speed and composition to demonstrate how these parameters influence dilution, microstructure, hardness and corrosion rate. A corrosion-rate equation is introduced and used to normalize results across studies. Remaining challenges include predicting long-term performance in real boilers, controlling crack susceptibility and designing dimensionless parameters to guide alloy selection. Future research should focus on integrating in-situ monitoring, high-throughput alloy design, functionally graded interlayers, rare-earth and nano-additive grain refiners, hybrid deposition, machine-learning-guided process control and standardized accelerated tests. Integrating materials innovation with predictive process control could make laser cladding an indispensable technology for sustainable waste-to-energy systems.</p>
