Innovation of metallic glasses has been provided the ease of access to advanced properties and new horizons for their exclusive applications. Some of their excellent properties are high mechanical properties, good corrosion resistance and magnetic response. Fe-based metallic glasses have exceptional mechanical and corrosion resistance properties. Through different Fe-based metallic glasses, the Fe-Cr-Mo-B-C alloys have well glass-forming ability and high corrosion resistance. HVOF, electrochemical methods, sputtering and laser cladding are general methods for producing the amorphous metallic glass coatings. Among the various methods, the laser cladding has the features of low wasting of time and materials, automatic setup, high dissolution create capability, high cooling rate, and high precision. Weak plasticity at room temperatures is the main problem in Fe-based metallic glasses. This has been result in cracks and brittleness of the specimen. According to the abovementioned comments, in the current research, the copper and nickel has been used as alternatives for boron in a copper containing composition of Fe53.4Cr20Mo16Cu0.6C10 and nickel containing of Fe42Cr20Mo16Ni12C10 respectively for promoting the plasticity of the resulting coatings. The preplace compositions have been prepared using the elemental powder mixtures and polyvinyl alcohol as an adhesive and have been applied on 316L stainless steel substrates. The Nd:YAG laser with the scan speed of 4, 6, and 8 mm/s has been used for laser cladding of preplaced mixtures. Liquidation and solidification of the preplaced mixture on the 316L substrate has been resulted in producing a clad material. X-ray diffraction (XRD), scanning electron microscopy (SEM) and field emission electron microscopy (FE-SEM) have been used for characterization of the resulting coatings. Corrosion resistance of the coatings has been evaluated in 3N HCl solution using the potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) methods. Mechanical properties of clads has been evaluated using the microhardness test. The results obtained revealed that, the minimum thickness of clads is 200 micrometer with high adhesion to the substrate. In addition, increasing the scan speed of laser would result in decreasing the surface inhomogeneity of clads. In copper containing composition of Fe53.4Cr20Mo16Cu0.6C10 , after the laser processing, combination of amorphous phase and crystalline network of ferrite has been created. The results have been shown that, using the laser scan speed of 8 mm/s, more than 90% of the structure has been transformed to the amorphous phase. In addition, in this scan speed, the ferrite crystal network has been broken and well distributed and the resulting microhardness has been reached to 824Hv. The corrosion current density of the resulting clads has been reduced 5 times the steel 316L and corrosion potential has been increased more than 50 mV. The EIS results revealed that the polarization resistance of the copper containing clads has been reached about more than 7 times of the substrate. The cladding using the nickel containing composition, Fe42Cr20Mo16Ni12C10, resulted in a ferritic/austenitic microstructure (50/50) using the scan speed of 6mm/s as a duplex stainless steel structure. The corrosion current density of the claddings has been reduced 9 times of the 316L stainless steel substrate and the corrosion potential has been increased more than 70 mV. The EIS results revealed that the polarization resistance of the nickel-containing clads has been reached about more than 13 times of the substrate. Overall it must be mentioned that, use of copper and nickel instead of boron in the composition of Fe-based metallic glass claddings, and use of laser cladding method with the proper laser scan speed, attainment of the minimum of 50% and maximum of 90% amorphous phase in the crack-free claddings, along with increasing the hardness and corrosion resistance would be conceivable.
