Study On Tribological Properties Of Textured Stainless Steel Surface Based On Composite Preparation Process

The surface texture has the positive effect of improving the bearing capacity,reducing the friction and wear,improving the working life,improving the tribological performance and so on,and has become an important research direction in the current field of tribology.Aiming at the existing metal surface micro-weaving constitutive methods,there are deficiencies such as expensive equipment,complicated process and long processing cycle.This paper proposes a novel composite preparation process combining electric field induction with chemical/electrolytic transfer,and preparation of surface texture on stainless steel.And the tribological properties were studied experimentally to explore the feasibility of the preparation process for surface texture.A model is set to analyze the electric field induced process parameters(external electric field,plate spacing,initial film thickness of the polymer)and structured template parameters(the aspect ratio of the template,duty cycle)for the polymer under the electric field Morphological changes in the law of influence by COMSOL Multiphysics.Based on the results of simulation analysis,an electric field induction test of polydimethylsiloxane(PDMS)polymer material was conducted,and a PDMS template-free electric field induction test was conducted for stainless steel discs and ITO conductive glass plates,and the induction process parameters were analyzed.The influence of micro-texture on the growth state of the micro-texture was initially studied,and the electric field induced test of the structured template was initially carried out.The electric field induced molding process of the structured template was briefly analyzed to provide a mask for subsequent chemical etching and electrolytic transfer.The chemical corrosion process and electrolytic transfer molding process of stainless steel materials were analyzed using COMSOL Multiphysics.The potential changes of stainless steel materials were studied.The influence of electrolytic parameters(applied voltage,plate spacing,etc.)on the final processing morphology was analyzed.The chemical corrosion test was performed using an electric field-induced polymer mask to obtain a textured stainless steel surface.The influence of corrosion parameters(corrosion time,etching solution concentration)on the corrosion morphology was analyzed;the polymer mask ITO conductive glass was induced by an electric field and Stainless steel is a cathode and an anode.Electrospinning stainless steel surface texture test study,analysis of the electrolytic process parameters(processing time,processing voltage,anode and anode spacing)on the corrosion morphology,preparation of the textured stainless steel surface,Tribological performance studies provide the basis.Fluid simulation was used to analyze the effect of surface texture density and oil film thickness on the lubricating performance through FLUENT.The sliding friction properties of the stainless steel surface were analyzed by electrolysis transfer.The influence of the experimental parameters and texture parameters on the friction coefficient was analyzed.The impact sliding friction tribology test was conducted on the surface of the electrophoretic stainless steel textured surface using a self-made impact sliding test bench.The influence of the test condition parameters and texture parameters on the friction coefficient was studied.The composite preparation process was used for surface weaving.Test verification is provided.
