Comparison of selected surface topography parameters after the turning of Inconel 625 obtained by the additive techniques to the parameters of the material made by the traditional techniques
Journal Title: Archives of Mechanical Technology and Materials - Year 2018, Vol 38, Issue
Abstract
The paper presents the possibilities of additive manufacturing of the selected alloy, Inconel, for production of ready-made elements. The results of surface topography examination of the material manufactured with the use of the device 557 RPMI working in the LDT technology (LDT = Laser Deposition Technology) have been compared to those of a cold drawn material. The surface just after manufacturing in the two technologies has been compared to one after machining by means of variable machining parameters. The surface roughness parameter, Ssk is positive for all the surfaces of a sample made by the traditional technology, regardless of the feed. This means that most material is located close to the valleys. The surfaces are characterised by right-hand side asymmetry. In all the surfaces of the sample made by the additive technology, regardless of the feed value, the surface roughness parameter, Ssk, is negative, which means that most material is located close to the peaks.
