- Description: Abstract: Henicosyl-1,1,2,2-tetrahydrododecyltricholrosilane is a hydrophobic silane compound coated on AISI 304 substrate. The surface of the substrate was treated in two ways (silicon oxide and plasma oxide) for adhesion and interface between the inorganic substrate and organic coating. The wear performance of the coating as a comparison to the AISI 304 was investigated using vacuum tribometer and characterized by scanning electron microscope and atomic force microscope. The result showed that the silane compound did improve the wear property of the AISI 304 stainless steel. It also proved that silane can be used as wear resistance agent.

- Description: Abstract: The effects of Organofunctional moieties and the adhesion properties of hydrophobic [Tris(trimethylsiloxy)silyethyl]dimethylchlorosilane (Alkyl)] coated on AISI 304 to determine the corrosion resistance were investigated and presented. Two different types of adhesion, namely: silicon oxide and plasma silicon oxide films were grown on AISI 304 with the aid of an atomic‐layer deposition technique. The effects of the surface preparations on the functionality and the properties of the hydrophobic silane coating were characterized, using the scanning electron microscope (SEM) and the atomic force microscope (AFM) for morphology and topography. X‐ray diffraction (XRD) and attenuated Fourier‐transform infrared (FTIR‐ATR) were used for the chemical composition and the bonding structure, the water contact angle were measured and processed, as well as the determination of electrochemistry of the coated and uncoated surfaces. The results showed that the silicon oxide treated surface improved the durability of the silane film in the corrosive medium; and that has more chemical stability with the coating, when compared with the plasma silicon oxide and base material, which was distinctly discussed.

- Description: Abstract: INCONEL® nickel-chromium alloy 625 is widely used for its high strength, excellent corrosion resistance and creep resistance on prolonged exposure to aggressive environment. However, despite its properties and industrial application, its wear resistance is not entirely satisfactory. The article investigates and presents the tribological performance of Inconel 625 coating using reciprocating scratch test. High velocity oxyfuel (HVOF) method was used to deposit Inconel 625 film onto 304 stainless steel surfaces. The frictional behavior and wear data were studied in order to observe the effect of coating thickness on wear failure. The results revealed that coatings of higher thickness showed lower coefficient of friction, better adhesion and good wear resistance in comparison to the low coating thickness.
