“…The translation of the given name LENS by Sandia Corporation in Polish language itself varies. LENS is referred to as "laser fabrication of final shape and dimension," "laser-controlled mesh shaping," or more simply "LENS laser additive technique" (not to be confused with the different but similar SLM technique) [7].…”

“…For subsequent layers, the whole process is repeated, and the head is positioned at the starting point with the help of a moving table. In the case of manufacturing a three-dimensional component, these operations occur until a fully formed threedimensional solid is obtained [7].…”

“…initiate directional grain growth. In addition, the high temperatures resulting from laser exposure also make it difficult to produce a coating with low roughness [7]. However, among the main advantages in favor of this technology is the possibility of obtaining a dense and continuous coating on parts with complex geometries, as well as providing better protection under high-temperature oxidation conditions, enabled by a low proportion of pores and very good adhesion of the coating to the substrate [8].…”

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 evaluated 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

There is increasing pressure on the automotive industry for further reduction of CO2 and particulate (PM10, PM2.5) emissions. One of the main issues is the fine dust resulting from the wear of the brake disc/brake pads, which is considered to be a major source of non‐exhaust traffic‐related emissions, particularly in urban locations. Carbide coatings are the state‐of‐art solution for controlling rotor wear. The challenge of cost‐effective serial production for automotive applications can be mastered by high power laser cladding.
