The Effect of MoS2 in Organic Coating on the Corrosion Resistance of 316L Stainless steel in 3.5 % NaCl Solution

Austenitic stainless steels have excellent corrosion resistance in various environments so they are used as essential material for several parts such as pipeline pumps and structural steel in many industries. Among them 316L stainless steel has good mechanical properties with high corrosion resistance; therefore it is regarded as the one of the most effective materials in various corrosive filed. However in marine atmospheric environments it could be suffered pitting-type corrosion due to seawater and deposition of airborne sea salts which has high chloride concentration. For this reason corrosion protection in high chloride environments is the major concern in many industries at the same time several corrosion mitigation methods are studied and developed in various fields.Vegetable oils are highlited as new effective organic coating which is a nontoxic nondepletable domestically abundant nonvolatile and biodegradable resource. Polar molecules present in the oils can be absorbed on metal surfaces and form the corresponding metal oxides which will enhance the stability of passivation and promote adhesion. Especially sunflower oil (SunFO) coating is reported as a effective corrosion inhibition organic film for carbon steel. However there is seldom studies for corrosion inhibition effect of the sunFO coating for stainless steel and reinforcement effects of the sunFO coating due to synthesis of other materials. Therefore in this study the sunflower oil is used as base coating and binding materials for 316L stainless steel.Recently the two-dimensional (2D) material is extensively researched for the modification of physical properties such as a mixure materials with polymeric organics because they affect corrosion resistance. Among the 2D meterials MoS2 is spotlighted becaues of semiconducting property between the metal and electrolytes. However many modifications such as CVD water transfer for surface coating with MoS2 are being phased out due to their high cost long time in process low throuput and harmful effects on environments. For many researches were conducted to improve stability and corrosion resistance with a mixture between the MoS2 particles and other organic coating material without the toxicant effects.In this study the reinforcement effect of MoS2 in organic coating on 316L stainless steel was investigated in 3.5 % NaCl solution. The electrochemical properties of organic coating according to MoS2 were evaluated by using electrochemical impedance spectroscopy (EIS) tests. Scanning electron microscopy (SEM) with Energy Dispersive Spectrometer (EDS) was used to observe the dispersion of MoS2 on the surface and cross section. In addition X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FT-IR) methods were performed to evaluate corrosion resistance of coating materials.
