TLDR
In this article, the L18 Taguchi robust plan was used to optimize the processing conditions of EN GJSFP 450-10 ductile cast iron and achieved the best results when using a minimum turning and burnishing feed ratio, minimum turning speed, a large nose radius of the turning tool, maximum burnishing speed and indirect burnishing force.Abstract:
When processing EN GJSFP 450-10 ductile cast iron. The L18 Taguchi robust plan was used to optimize the processing conditions. The application of this method allowed determination of optimal conditions taking into account the conditions of pre-turning and burnishing. Due to optimization, the value of the S/N parameter increased by 25%. Best results were achieved when using a minimum turning and burnishing feed ratio, minimum turning speed, a large nose radius of the turning tool, maximum burnishing speed and indirect burnishing force in the presence of base oil. The phenomenon of technological heredity action was observed when roller burnishing, in other words, the influence of the pre-burnishing process conditions on the Ra surface roughness parameter after burnishing.read more

Grain refined and basal textured surface produced by burnishing for improved corrosion performance of AZ31B Mg alloy
Z. Pu,Guang-Ling Song,S. Yang,José Outeiro,José Outeiro,Oscar W. Dillon,David A. Puleo,I.S. Jawahir +7 more
TL;DR: Grain refinement and strong basal texture were produced on AZ31B Mg alloy surface concomitantly by a newly developed severe plastic deformation (SPD) process, severe plasticity burnishing (SPB), which was attributed mainly to dramatically reduced grain size and strongly basal-textured grain orientation.
