Abstract

Papaya leaf extract used as an inhibitor in carbon steel sample AISI 1020, was immersed in a 3% carboxy NaCl medium. By varying the immersion time of 4 days and 8 days, and also the concentration of inhibitor 0%, 3%, 5% and 7%. After the treatment of the sample obtained the slowest corrosion rate calculation results in AISI 1020 4.5 samples and the fastest in the AISI 1020 8.7 sample. The inhibitor used has the most efficient efficiency value in the AISI 1020 4.5 sample and the inefficient value in the AISI 1020 4.7 sample. The XRD characterization results show that the crystalline structure formed is BBC with pure Fe phase. The SEM characterization shows the surface morphology of the steel sample, visible in the sample without the addition of more inhibitors than the sample with the added inhibitor. In addition, cracks do not appear on the AISI 1020 4.5 sample. Characterization of EDS in the sample seen elements of Oxygen (O) and Clorin (Cl) which indicates that the sample has been corroded.

Abstract. Research on the effect of Pb doping is 0; 0.1; 0.2; 0.3 and 0.4 to the phase growth of the Bi-2212 Ca 1,10 superconducting material was carried out by the solid method at a calcination temperature of 800°C for 10 hours and sintering temperature of 830°C for 20 hours. The effect of Pb doping on the phase growth of superconducting material can be seen by volume fraction, impurity, and degree of orientation. The results showed that samples without doping Pb (Pb 0) had lower volume fraction values than samples with doping Pb (Pb 0.1-0.4). Addition of Pb doping (Pb 0.1-0.4) will increase the volume fraction. The highest volume fraction (Fv) in doping Pb 0.4 was 80.99%, whereas the lowest volume fraction on doping Pb 0.1 was 67.73%. Samples without doping Pb (Pb 0) had a lower orientation grade value than samples with doping Pb (Pb 0.1-0.4). The addition of Pb doping 0.1 and 0.4 has a higher orientation degree compared to Pb doping of 0.2 and 0.3. The sample with doping Pb 0,1 has the highest orientation degree value that is 24,87%. Based on the SEM results all the seals have shown layers arranged in a direction (oriented) with empty space between the slab (void) is relatively small.

Abstract

Corrosion inhibition of areca nut extract (Areca catechu) as the resistor of corrosion rate in low carbon steel with HCl and NaCl corrosive medium concentrated at 3% had been reasearched. The C-Mn steel corrosion rate was examined during a 96 hours of submersion with and without the addition of areca nut extract with the concentration rate at 10%, 15%, and 20% respectively. The examination was done with the weight loss method. The result of the research shows that the use of higher the concentration of areca nut extract resulted in the decrease of corrosion rate and the increase of corrosion inhibition capability. The highest rate of corrosion effectiveness was found in the 20% concentration in both HCl and NaCl with the rate of 86,06% and 85,62% respectively. The result of X-Ray diffraction (XRD) characterization showed that the phase formed was pure Fe. Scanning Electron Microscopy (SEM) characterization showed uneven clusters with smaller size. Holes and cracks were not formed that the corrosion rate was lower compared to the sample without inhibitor addition. The characterization Energy Dispersive Spectroscopy (EDS) in the sample without inhibitor showed the presence of Cl substance.
