The corrosion inhibition of ST37 Carbon Steel in 1.0 M HCl by aquatic extract of coconut has been studied as a possible source of green inhibitor using the potentiodynamic polarization and electrochemical impedance spectroscopy techniques. The aquatic extract of coconut have many advantages over classical techniques of sample preparation of plant gums (such as drying and solvent reflux).Pol...

BACKGROUND Inflammation is often considered to play a crucial role in epilepsy by affecting iron status and metabolism. In this study, we investigated the curative effect of auricular acupuncture and somatic acupuncture on kainic acid- (KA-) induced epilepsy in rats. METHODS We established an epileptic seizure model in rats by KA (12 mg, ip). The 2 Hz electroacupuncture (EA) was applied at au...

these days, most of the marine structures which are constructed and used in persian gulf, are made of st37 steel. due to oil and gas sources excavated, the number of these structures is constantly increasing. on the other hand, these types of structures are exposed to corrosive environments and it is seriously critical for these structures to be used for many years. coal tar epoxy (trade name),...

Nowadays, in order to reach minimum production cost in machining operations, various optimization methods have been proposed. Since turning operation has different parameters affecting the workpiece quality, it was selected as a complicated manufacturing method in this paper. To reach sufficient quality, all influencing parameters such as cutting speed, federate, depth of cut and tool rake angl...

Henna leaves extract (Lawsonia inermis L) is used as a corrosion inhibitor in St37 steel soaked 3% HCl corrosive medium. To find out the effect of concentration on rate steel, variation 0, 3, 5, 7 and 9%. Corrosion testing done by mass loss method. was tested low carbon with without inhibition henna for 6 days. The results showed that greater used, would decrease ability to inhibit increase. gr...

The extract of pandan leaf used as corrosion inhibitor St37 steel in NaCl 3% solution. To determine the effect concentration and immersion temperature on is done with variation there were 0, 1,8, 1,2, 1,4% 27°C 40°C. Corrosion rate testing by weight loss method. Increased along increasing sample loss. Inhbitor most efficient at 1.2% soaking Samples also characterization XRD SEM-EDS. results sho...
