Fast cooling speed (up to 10^6 K\/s)<\/strong>, which allows for the rapid solidification process. This results in fine-grain structures or new phases that cannot be achieved through equilibrium states, such as metastable phases or amorphous materials.<\/p>\n\n\n\n

Low dilution rate (<5%)<\/strong>, with a firm metallurgical bond or interface diffusion bond between the cladding and the substrate. By adjusting the laser processing parameters, \u043b\u0430\u0437\u0435\u0440\u043d\u0430\u044f \u043d\u0430\u043f\u043b\u0430\u0432\u043a\u0430<\/strong> can achieve low dilution coatings with controllable composition and dilution.<\/p>\n\n\n\n

Minimal heat input and distortion<\/strong>, especially when using high-power-density rapid cladding, where deformation can be reduced to within the assembly tolerance of the part.<\/p>\n\n\n\n

No limitation on powder selection<\/strong>, especially for cladding high-melting-point alloys on low-melting-point metal surfaces.<\/p>\n\n\n\n

Large thickness range of cladding layers<\/strong>, with a single powder feed layer ranging from 0.2 to 2.0mm.<\/p>\n\n\n\n

Selective cladding<\/strong>, resulting in minimal material consumption and excellent cost-performance ratio.<\/p>\n\n\n\n

Laser beam aiming<\/strong> enables cladding in hard-to-reach areas.<\/p>\n\n\n\n
