“…Following the literature analysis regarding the failure of personal protective equipment as part of a fall arrest system as a result of damage to the connecting elements, it was found that carabiners' durability is affected by several factors which are related to the load conditions, environment or their geometry [1]. Therefore, it was observed that the decommissioning of carbon steel carabiners is due to the appearance of iron oxides on their surface or doubts regarding the appearance of internal cracks [7,8].…”

This study approaches the issues which appear during carabiner use and analyses the possibility to eliminate them. Therefore, to improve the corrosion resistance of carbon steel, used in carabiners manufacturing, three different insoluble phosphate layers were deposited on the samples’ surface. The layers were obtained by immersion in zinc-based phosphate solution, zinc/iron-based phosphate solution and manganese-based phosphate solution, Afterwards, to protect against mechanical shocks, a layer of elastomer-based paint was deposited. Furthermore, to reduce rope wear by decreasing the value of the coefficient of friction, the samples were impregnated in molybdenum disulfide-based lubricant. This study aims to analyse the corrosion behaviour of the layers deposited on the carbon steel surface in three of the most common corrosive environments (rainwater, seawater and fire extinguishing solution) by linear and cyclic polarisation. The overall results show that all types of deposited layers increase the corrosion resistance of C45 steel. The experimental results revealed that the samples coated with a phosphate layer obtained by immersion in the zinc-based phosphate solution possess the highest corrosion resistance among the phosphate samples.

“…Corrosion is the external disintegration of metals or alloys in particular condition. Several metals evidence a great corrosion resistance than others and this can be ascribed to a few particular points such as their chemical elements, the environment of electrochemical reactions itself and others [1,2]. The problem that causes by corrosion not only intrude the economic, but it might also disturb the social environment and the safety and health of the people, that live nearby corrosion environment or working in the industries.…”

The analysis of anticorrosion coating by using Andrographis paniculata (kalmegh) leaves extract (KLE) as an additive to protect stainless steel 316L that immersed in seawater environment was successfully carried out. The anti-corrosive coating is the combination of selected binder, pigment, solvent, and additive. Andrographis paniculata leaves extract was selected as an additive due to excellent antioxidant properties. There are five types of coating with different concentration which are C1 (0 wt.%), C2 (3 wt.%), C3 (6 wt.%), C4 (9 wt.%) and C5 (12 wt.%). The coated substrate the immersed in seawater for 30 days and taken out for each subsequent 10 days for analysis. The analysis involves optical, electrochemical, and morphology studies. A few techniques involve including of Fourier transform infrared spectroscopy (FTIR), ultraviolet-visible spectroscopy (UV-Vis), electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PP) and scanning electron microscope with energy-dispersive X-ray spectroscopy (SEM/EDS). The result of FTIR shows several functional group presence in the KLE that can enhance anti-oxidation properties such as phenol, carboxylic acid, carbonyl, and amide. The presence of andrographolide compound obtained from UV-vis analysis at peak absorption spectrum 229 nm. Electrochemical analysis result from EIS, the most efficiency coating was predicted at C3. Hence, it has higher R ct value and low C dl value. The result in EIS is corresponding to PP; hence the result of corrosion rate at C3 is the lowest value, which is 0.00211 mm/year at 30 th day immersion. The observation on the surface morphology of the coating also shows that C3 that has a smooth surface with less pitting, cracks, and salt precipitate when compared to another coating. The addition of KLE increases the efficiency of anticorrosion coating with optimum concentration, which is 6 wt.%.

“…Numerous coatings have been developed to prevent corrosion and enhance the service life of engineering components [17][18][19][20][21]. The effects of nanoscale can be used to create coatings with significantly optimized or enhanced corrosion properties.…”
