In this study, Al-containing coatings were prepared on the surface of AZ31 magnesium alloy by pack-cementation through box-type furnace heating (BFH) and induction (IH) methods. Phases, microstructure, composition, performance characterized X-ray diffraction technique (XRD), secondary electron imaging (SEI), backscattered (BSEI), energy dispersive spectroscopy (EDS), Vickers hardness test poten...

The electrochemical behavior of 304 austenitic stainless steel (304ASS) was studied by different methods such as potentiodynamic polarization, EIS, SEM, and Raman spectroscopy. Potentiodynamic polarization data suggest that ASS could be more susceptible to corrosion due the presence H2S. coexistence H2S Cl?-type ionic species in lead a decrease resistance compared H2S-free condition. It is seen...

In this paper, the role of nickel-20 chromium and TiO2 nanoparticles additions for enhancement corrosion resistance microhardness organic zinc-rich coatings were investigated. Three coating samples prepared by new in different amounts that experimentally predicted. Particle sizes micrographs examined scanning electron microscope (SEM) chemical composition was analyzed energy dispersive spectros...

The performance of an Imidazoline based commercial corrosion inhibitor on CO2 corrosion of mild steel was investigated in a Cl- containing solution employing linear polarization resistance (LPR), potentiodynamic polarization and monitoring corrosion potential techniques. Experimental results showed that an increase of the commercial inhibitor concentration up to 500 ppm increases the RP value a...

Nickel films of 300 nm thickness were deposited by electron beam evaporation at room temperature on 316 stainless steels. Corrosion studies of Ni coated 316 SS have been performed after N+ ion implantation at different energies of 20, 40, 60 and 80 keV. The structure and surface morphology of the films were evaluated using X-ray diffraction (XRD), atomic force microscope (AFM) an...

Alkaloids are aromatic hydrocarbons with nitrogen as heteroelements in the ring structure that responsible for bonding metal surface and help to reduce corrosion of metals such mild steel (MS) an acidic medium. In this study, alkaloid Rhynchostylis retusa (RR) was extracted by solvent extraction method confirmed chemical test well FTIR spectroscopic test. Extracted alkaloids were tested green i...

This laboratory study aimed to reveal the inner connects between microstructure and corrosion properties of a RE microalloyed ultra-thin cast strip (UCS) steel. The mainly consisted homogeneous polygonal ferrite (PF) with small amount pearlite (P), while adding multiple alloying elements led appearance granular bainite (GB) bainitic (BF). strongly promoted homogenization refinement by segregati...

The present research investigates the influence of surface roughness imparted by cold finishing processes on localized corrosion resistance stainless steel. Five different alloys were studied: ferritic AISI 430, martensitic 430F, austenitic 303, 304L, and 316L. It was demonstrated that grinding process, executed previously drawn bars, leads to an improvement in according results obtained with e...
