Abstract

Abstract. Avocado leaves extract (Persea americana M.) is used as an inhibitor to the sample of SS-304 Stainless steel which cures in HCl 1M Corrosive Medium for 168 hours, the inhibitor concentration variation added 0%, 2%, 4%, 6%, 8% and 10% respectively. The corrosion rate is measured by using loss-weight method. The results show the lowest samples is 0,37 mm/y of 6% and the highest 10,75 mm/y of 0%. Inhibitor efficiency to the sample SS-304 Stainless steel potrays the effectively progress to 96,55% with 6% concentration. X-Ray Diffaraction Results accquired BCC and FCC with Fe- dan Fe- phase along with SEM that forms agglomeration, cracked, and hole which result on its corrosion. In addition EDS contains Oxygen (O) and Chlorine (Cl) Element which indicate that stainless still has affected by corrotion. Thus from three samples which characterized and measured show that avocado leaves effectively as an inhibitor to the sample SS-304 stainless steel in HCl 1M corrosive medium.
