Electrochemical synthesis of poly ortho toludine (POTD) was achieved on Teflon coated cylindrical stainless steel electrodes with base diameter 2mm . Aniline in 2-propyl pentatonic acid solution was polymerized on the surface of stainless steel using cyclic voltametry technique. Adherent and red polymer films were obtained on the electrodes.. The corrosion inhibitive performance of POTD+2PPA , ...

The effect of chloride ions concentration on the electrochemical behavior of AISI 410 stainless steel in the simulated concrete pore (0.1 M NaOH + 0.1 M KOH) solution was investigated by various electrochemical methods such as Potentiodynamic polarization, Mott–Schottky analysis and electrochemical impedance spectroscopy (EIS). Potentiodynamic polarization curves revealed that increasing chlori...

The press formability of a dual-phase stainless steel sheet consisting of ferrite and austenite phases was estimated from a viewpoint of texture using plastic strain ratios (r-values). From the comparison of the mechanically obtained r-values by tensile test and the r-values calculated from the crystal orientation distribution functions (ODFs) of each phase, we found the ferrite phase contribut...

In this research work a series of tests were conducted in order to determine flank wear and cutting force FY on hard AISI 440 C martensitic stainless steel and SCM 440 alloy steels. The operating parameters are cutting speed, feed rate and a constant depth of cut to investigate the flank wear and cutting force. No cutting fluid was used during the turning process. The cutting tool used was CBN ...

Purpose: To evaluate the effect of carvacrol against Salmonella saintpaul biofilms on stainless steel surface. Methods: The effect of carvacrol on planktonic cells of S saintpaul was evaluated by determining the minimum inhibitory concentration (MIC) and minimal bactericidal concentration (MBC). The action of carvacrol on S. saintpaul biofilms on stainless steel surface was evaluated on establi...

PURPOSE To compile a survey of the longevity and reasons for failure of stainless steel crowns, amalgam, glass-ionomer, composite and compomer restorations in stress-bearing cavities of primary molars. METHODS This work reviewed the dental literature of 1971 up to July 2003 for longitudinal, controlled clinical studies and retrospective cross-sectional studies. Only studies investigating the ...

PURPOSE This study was conducted to evaluate the effects of full-coverage all-ceramic zirconia, lithium disilicate glass-ceramic, leucite glass-ceramic, or stainless steel crowns on antagonistic primary tooth wear. MATERIALS AND METHODS There were four study groups: the stainless steel (Steel) group, the leucite glass-ceramic (Leucite) group, the lithium disilicate glass-ceramic (Lithium) gro...

This paper demonstrates flexible and stretchable microneedle patches that combine soft and flexible base substrates with hard and sharp stainless steel microneedles. An elastomeric polymer base enables conformal contact between the microneedle patch and the complex topography and texture of the underlying skin, while robust and sharp stainless steel microneedles reliably pierce the outer layers...

Anodes of 304 stainless steel have been processed by a continuous wave Yb fiber laser with a wavelength of 1.064 lm and subjected to 50 keV electron bombardment in order to determine the extent to which hydrogen outgassing is reduced by the laser surface melting treatment. The results show a reduction in outgassing, by approximately a factor of four compared to that from untreated stainless ste...
