Corrosion and wear resistance has always been among the highly important parameters forequipment and piping in oil and gas facilities. The corrosion is considered as the deteriorationof materials as a result of electrochemical reaction with surrounding environment or containedservice. Wear is defined as the removal and deformation of material due to mechanicalinteraction between two or more objects. Increased demand for surface protection and reducedoperative costs touts for protective coatings with improved mechanical, electrochemical, andtribological properties.
This paper describes the deposition of various Ni-P composite coatings over an AISI 1012steel sample through an electroless coating process. The composite coatings wereprepared using various ternary additives namely carbon nanotubes, titanium, and alumina.Coated samples were characterized over alongside surface and cross-sections usingenergy dispersive spectroscopy. Corrosion behaviors of composite coatings werecharacterized using potentiodynamic polarization. Mechanical and tribological attributeswere evaluated using Vickers hardness and nano-indentation, respectively. Among thecandidate additives, Titanium reached the maximum incorporation (upto 30 wt.%). Aluminaparticles showed competing compromise between surface smoothness and deposition rate.Carbon nanotubes improved lubrication effects by reducing co-efficient of friction (checkedusing universal micro tribometer). Alumina manifested the highest hardness and the leastcorrosion rate in comparison to the candidate additives.
In this paper, a case study is presented for a marine structure for which modelling has been used to predict the protection potentials over the life of the structure.
The aim of any digital transformation of integrity management and in particular corrosion control is the improvement of communication efficiency, planning efficiency and maintenance efficiency. Key issues are predictive maintenance and clarity of the information available so engineers can make informed decisions. Therefore it is not just a question of collecting more information but also the way that information is used and shared with the decision-makers.

Duplex stainless steels (DSSs) are based on the Fe-Cr-Ni system and are constituted of 30 to 70 % ferrite and austenite. They combine high tensile strength, good toughness, weldability, and excellent corrosion resistance including stress-corrosion cracking and resistance to localized corrosion.1-3 DSSs can be classified according to the Pitting Resistance Equivalent Number (PREN = Cr + 3.3 Mo + 16 N) in lean duplex (PREN= 22-27), standard (PREN = 28-38), super duplex (PREN = 38-45) and hyperduplex (PREN > 45).
The threshold hydrogen content of a material regarding hydrogen embrittlement plays an increasingly important role in corrosion research. This value indicates the hydrogen content to which the material can be used without failure. However, when determining the threshold hydrogen content, different test methods, different analysis methods and different interpretations of the results come together. This paper is intended to provide a guideline for the determination of the critical hydrogen concentration of high strength steel wire samples.
