The Research of the Surface Profile after Profiling of Inconel 738LC

AbstractProduction of so-called superalloys is increasing in the present. This paper is about Inconel 738 LC. There are main mechanical properties as well as chemical composition of Inconel 738 LC in this paper. Special properties of superalloys cause, that they are very hard machining materials, mainly thanks to their high thermal stability during machining. For this reason it was necessary to measure the surface roughness after machining turbine blades made of Inconel 738LC depending on profiling. Roughing and finishing of Inconel 738 LC was used to get nearly the best parameters of the surface roughness
