TY - JOUR N2 - This article presents the results of a research on the behavior of NiCrAlY coating obtained by the LENS method on austenitic stainless steel type 316L under long-term annealing conditions at 1000°C for 25, 100 and 250 hours. The morphology of the NiCrAlY layer as a function of annealing time and temperature was characterized. The chemical composition and distribution of alloying elements were eval-uated using scanning microscopy and micro-area chemical composition analysis. It was revealed that NiCrAlY coatings deposited by LENS method are characterized by good metallurgical quality. The long-term annealing of the NiCrAlY coating led to microstructural changes in the form of the disappearance of the original dendritic structure and the formation of a solid solution of nickel with chromium and a small amount of aluminum, as well as chromium α-Cr precipitates and Ni-Y-type phases. The effect of increasing iron concentration in the coating due to diffusion-to-core processes was also found L1 - http://journals.pan.pl/Content/125447/PDF-MASTER/AFE%204_2022_17_final.pdf L2 - http://journals.pan.pl/Content/125447 PY - 2022 IS - No 4 EP - 120 DO - 10.24425/afe.2022.143959 KW - NiCrAlY KW - LENS KW - Additive manufacturing KW - Long-term annealing KW - Microstructural stability A1 - Szymański, K.K.
