mechanical properties - Opis:
- In this study, Ni20Cr coatings were obtained by cold spraying on an aluminum alloy 7075 substrate. 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.
