Burnishing Operation for Corrosion Resistance Improvement of AISI 1017 Carbon Steel

Abstract

This research deal with investigation the influence of burnishing operation on the corrosion resistance of low carbon steel. The burnishing operation involve pressing a hard roller made from stainless steel on the surface of the rotatory shaft, this operation leads to the formation of a plastic deformation on the surface of the steel. Burnishing feed and burnishing speed were the variables which are used for this study. The first group involve hold burnishing speed on 125rpm with variable feeds of 0.6, 0.9, 1.5, 2 and 3mm/rev and the second group involve hold burnishing feed on 2 mm/rev with variable speed of 85, 125, 370, 800 and 1200rpm. The corrosion test was done via applying potentiostat at 23ºC in sample of water from Tigress River at upstream Samara’a barrage and groundwater (Yousifia salt well 90m below ground surface). The result showed that there was improvement in corrosion resistance of the steel were the corrosion rate reduced from 7.577 mpy to 0.685 mpy in sample of water from Tigress River and from 8.878 mpy to 1.38 mpy sample of water from groundwater.

Effect of slide burnishing on the corrosion resistance and surface roughness on high strength steels

“…While some authors have reported that slide burnishing provides several benefits as improving corrosion which can be attributed roughness, grain size, etc. 13,20,21,24,26,27 The above results suggest that burnishing process applied over zinc coating does not show a significative variation on its corrosion resistance. Zinc is known for its high resistance to corrosion thanks to the formation of a protective layer of zinc oxide on its surface.…”

“…Similar to the afore mentioned research, other studies demonstrate that the use of the appropriate burnishing parameters improves the corrosion resistance of different types of metallic materials, such as: A53 steel, X5XrNi 18-10 stainless steel, X6CrNiMoTi17-12-2 stainless steel, AZ31B Mg alloy, AISI 1017 carbon steel, 2024 aluminum alloy, and Mg-Al-Zn alloy. [21][22][23][24][25][26][27] Literature shows that the improvement in corrosion resistance is mainly attributed to the enhancement in surface roughness, grain refinement, strongly basaltexture grain orientation, and the introduction of compressive residual stresses.…”

Effect of slide burnishing on corrosion potential in ASTM A-36 steel

“…While some authors have studied the effect of burnishing on corrosion, including roughness, grain size, etc. [9][10][11][12][13][14], and these studies clearly indicate a change in the corrosion potential, this aspect is not or partially addressed in their results and discussions. Consequently, many authors attribute the alteration in corrosion potential mainly to roughness.…”
