Surface Hardness Modification of Selective Laser Melted Ti6Al4V Parts by Sliding Friction Diamond Burnishing
نویسندگان
چکیده
Selective laser melting (SLM) is a frequently used additive manufacturing technology for creating metallic, especially Ti6Al4V parts. After the production by SLM usually postprocessing necessary several reasons. Here sliding friction diamond burnishing applied as procedure.In this paper an experimental study of surface hardness improvement selective melted ELI cylindrical parts demonstrated. The modified machining. design experiment method was to investigate effect five factors (two and three machining parameters) on modification.It shown that both makes significant improvement, most important ones are power, scan speed during manufacturing, force factor postprocessing. Empirical formulas fit measurement data, visualized plots. Relationship between strongly nonlinear. In investigated parameter window has always positive improvement.Electron microscopic investigations show change in can be related four main morphological changes: compression plastic deformation protrusions, attenuation valleys, formation inner cavities creation small protrusions tool. This extended conference published proceedings book XXXI. International Welding Conference (Kecskemét, Hungary).

To improve the biocompatibility of implants, surface medication is a common practice. Depending on the surface medication process, the physical and/or chemical properties of the surface are altered, keeping the bulk properties same. The flexibility and wide application potential of laser as a surface modification tool gives it certain advantages over the traditional physical and chemical proces...

Burnishing is a chip-less finishing process, in which a hard roller or ball presses the surface layer of part to perform plastic deformation in the surface layer and produce improved finish, enhanced hardness and compressive residual stresses on the surface of special materials such as Aluminum and Brass. In the following research, the effect of input parameters such as feed rate, cutting speed...
