through super-hard wear-resistant surface electrode surfacing D707 in Low-carbon steel. We have analysis the effect of welding process parameters and post-weld heat treatment process on low carbon steel surface hardness of cladding layer. The experimental results show that: after quenching hardness value no significant change; But after annealing the hardness value decreased and after annealing the crystal grain of the underlying tissues uniformization become tiny. micro-hardness testing is carried out in the weld cross-section, we have find out that from the base metal to the cladding layer the surface hardness values is getting higher and higher, while the indentation is getting smaller and smaller. Because hardness is a measure of wear resistance materials, thus it can indirectly show that when low-carbon steel surface electrode in the super-hard wear-resistant surfacing welding layer, it can improve the surface hardness of low carbon steel and improve wear resistance of low carbon steel surface.

Corrosion inhibitors are vital in industry for protection and prevention of surfaces from corrosion attack. There is need to have green inhibitors that are environmentally friendly and not hazardous to use. Extract from stem of banana (Musa species: Musa-Acuminata) was considered as green inhibitors. Extracts from the stem of banana was subjected to physico-chemical, phytochemical screening and corrosion test using gravimetric measurement with a low carbon steel flat bar coupon. The corrosion inhibition mechanism of the plant extract on the low carbon steel surface in 1M HCl and H2SO4 acid at different temperatures (30 to 60oC) showed that the inhibition efficiency (IE) increased with increase in concentration of the inhibitor (15ml to 75ml) but decreased with increase in temperature (303K to 333K) for the inhibitors throughout the test period, indicating a physisorption of extract on the carbon steel surface. The adsorption on the low carbon steel surface agrees with the Langmuir adsorption isotherm. The inhibition efficiency of the extract was above 50% in both media with banana extract having 69.55% inhibition efficiency in H2SO4 solution
