The corrosion tests were conducted in brine solution saturated with H2S and two type of iron compounds (FeS and FeSO4).
The present work aims to investigate the effect of ferrous ion on the corrosion behavior of 410SS and further understand the corrosion mechanism of martensite stainless steel in H2S environment, through weight loss test, scanning electron microscopy (SEM) and X-ray diffraction (XRD).

Common commercial fertilizers contain “mobile” nitrogens that can be easily transformed into other nitrogen compounds.
This is because nitrogen can be easily transformed into other nitrogen compounds that can not be absorbed by plants in the form of available nutrients such as ammonium ion (NH4+) dan nitrate ion (NO3-).
The polyurethane multilayer method aimed to withhold nitrogen as nutrition longer than uncoated granular fertilizer.
Then, devarda alloy was added into 10 ml of sample to perform distillation in Nitrogen Analyzer GERHARDT type Vapodesk.
This is also in line with statements on a research journal about nitrogen release behaviors on field tests [18].

Chemical composition analysis of green plantain peel ash (GPPA) shows the presence of compounds such as SiO2, Al2O3, MgO, K2O, CaO, SO3 and Fe2O3 [34,35].

The present investigation aims at revealing corrosion mechanism of this steel in different environments.
Owing to the restricted resolving power of XRD, a lot of crystallite contained in rusts could not be identified, which along with some actual amorphous compounds are called as “X-ray Amorphism” in the present investigation.
It is well established that enrichment of alloy elements in rust layers originates from selected corrosion of iron.

Carbonaceous compounds, such as activated carbon, single-walled carbon nanotubes (SWCNT), double walled carbon nanotubes (DWCNT), and multi-walled carbon nanotubes (MWCNT) have attracted a considerable attention as raw materials for nano-scale, nanocomposite in particular, enhancement [5-7].
Continuously, PPy/f-MWCNT is considered as an excellent NCs compounds in which cost-effectiveness, high mechanical strength and chemical stability as well as relatively high electrical conductivity can be obtained; the latter is mainly attributed to the considerable surface area and good adhesion to substrate [9].
This was accompanied with energy dispersive x-ray (EDS) to examine the elemental compositions of the used compounds. 3.

Although there are several magnesium alloys, AZ alloys, such as AZ31B, that are widely used in industrial applications, as they have higher plasticity with lower aluminum content [1].
Many experiments have been carried out with the aim of improving the mechanical properties of the AZ31B alloy.
Mg alloys offer a lightweight alternative to comparable alloys, such as aluminum, which provides great potential for reducing the weight of systems.
