Effect of Indium Alloying with Lead on the Mechanical Properties and Corrosion Resistance of Lead-Indium Alloys in Sulfuric Acid Solution

2018-10-04 19:42:32 Keywords corrosion resistance, , Corrosion Rate, Electrochemical Impedance Spec, Corrosion Potential, Corrosion Current Density,
Effect of Indium Alloying with Lead on the Mechanical Properties and Corrosion Resistance of Lead-Indium Alloys in Sulfuric Acid Solution
Effect of indium alloying in various concentrations with lead on both microhardness and crystallite structure of lead-indium alloy was investigated. The corrosion behavior of leadindium alloys in 4 M H2SO4 acid solution was investigated by Tafel plot and electrochemical impedance spectroscopy (EIS) methods. The results of both Tafel plot extrapolation and EIS measurements exhibited the same trend. Generally, the corrosion ... Read more

Effect of DC-pulsed magnetron sputtering power on structural, tribological and biocompatibility of Ti–Zr–N thin film

2018-09-30 14:12:20 Keywords Ti-Zr-N film, Dc Pulsed magnetron sputtering, microhardness, wear rate, Surface Energy, corrosion resistance, Biocompatibility, osteoblasts cells,
Effect of DC-pulsed magnetron sputtering power on structural, tribological and biocompatibility of Ti–Zr–N thin film
The Dc. pulsed magnetron sputtering was employed to deposit Ti-Zr-N thin film on AISI 316 substrates. All the plasma parameters were kept to be constant except the plasma-processing power which was varied from 125 W to 250 W. The structure, tribological, electrochemical and biocompatibility properties of Ti-Zr-N films have been investigated. X-ray patterns confirmed the formation of solid solution phase ... Read more

Effect of rf Plasma Carbonitriding on the Biocompatibility and Mechanical Properties of AISI 321 Austenitic Stainless Steel

2018-09-30 14:16:40 Keywords Plasma Carbonitriding, Surface Energy, Wear, corrosion resistance, Blood Culture, Protein Adsorption,
Effect of rf Plasma Carbonitriding on the Biocompatibility and Mechanical Properties of AISI 321 Austenitic Stainless Steel
AISI 321 austenitic stainless steel was treated using rf plasma carbonitriding with the intention of use low-cost orthopedic implant material in biomedical applications. The treatment process was carried at low working gas pressure of 0.075 mbar in nitrogen-acetylene gaseous mixture to form a superficial carbonitrided layer. The samples were treated using rf inductively coupled at a fixed plasma-processing power of ... Read more

Role of Ni content in improvement of corrosion resistance of Zn–Ni alloy in 3.5% NaCl solution. Part I: Polarization and impedance studies

2018-09-27 18:01:18 Keywords Zn–Ni alloy, Ni content, corrosion resistance,
Role of Ni content in improvement of corrosion resistance of Zn–Ni alloy in 3.5% NaCl solution. Part I: Polarization and impedance studies
Zn plays an important role in the protection of iron and steel from corrosion in sea water, and the alloying of Zn and Ni can improve its corrosion resistance. The corrosion behavior of Zn–Ni alloys in synthetic sea water (3.5% NaCl, mass fraction) was studied using Tafel plot and electrochemical impedance spectroscopy (EIS) techniques. The corrosion resistance of the investigated ... Read more
