M. Ogórek, Z. Skuza, T. Frączek, Czestochowa University of Technology, Czestochowa, Poland The study examined layers were formed on the outer surface of austenitic stainless steel 304 under glow discharge conditions in the low-temperature and short-term ion nitriding. The outer layers analyzed in the work produced in parallel in the classical process of cathode and a novel method of “active scr...

INVESTIGATING THE EFFECT OF WELDING PASTE CONTAINING GRAPHENE NANOSHEETS ON BONDING PROPERTIES WELDED AISI 304 STAINLESS STEEL PRODUCED BY FLUX-CORED ARC

This study investigates transport phenomena in the weld pool (WP) of gas tungsten arc (GTA) welding of Nickel to 304 stainless steel. A finite element 3D simulation of fluid flow and heat transfer of spot welding without consumable is accomplished which leads to prediction of the weld zone shape, weld penetration and dilution of alloying elements. The model includes magneto-hydrodynamics (MHD),...

Electron beam butt welding of stainless steel (SS 304) and electrolytically tough pitched (ETP) copper plates was carried out according to central composite design of experiments. Three input parameters, namely accelerating voltage, beam current and weld speed were considered in the butt welding experiments of dissimilar metals. The weld-bead parameters, such as bead width and depth of penetrat...

in the present study, the effects of growth defects and chromium content loss on the degradation of corrosion andpassivation of cathodic arc evaporation (cae-pvd) of stainless steel coating were investigated in 2 m sulphuricacid solution. eds analysis indicated that the micro-particles were obtained during the coating growth. in addition,it was detected that the growth defects had poor adhesion...

Prediction of SCC risk of austenitic stainless steels in aqueous chloride solution and estimation of the time to failure as a result of SCC form important and complicated topics for study. Despite the many studies reported in the literature, a formulation or a reliable method for the prediction of time to failure as a result of SCC is yet to be developed. This paper is an &#10effort to investig...
