The obtained coatings were characterized by a uniform microstructure and low porosity. The sprayed coating has the same phase composition as the powder used. Next, the cold sprayed coatings were heat treated using a TRUMPF TLF 6000 TURBO (4 kW) CO2 laser. The laser surface melting of the coatings resulted in the formation of a columnar structure and an improvement in their mechanical properties. The Ni20Cr cold sprayed coatings after additional laser melting showed lower porosity and an increase in microhardness and Young`s modulus.}, type={Article}, title={Effect of Laser Surface Melting on Microstructure of Cold Sprayed Ni20Cr Coatings}, URL={http://www.czasopisma.pan.pl/Content/119263/PDF/AMM-2021-3-32-Sobon.pdf}, doi={10.24425/amm.2021.136390}, keywords={cold spraying, Ni20Cr coating, laser modification, mechanical properties}, }
