Improving mill productivity with advanced wear protection solutions, Solutions!, Online Exclusives, April , Vol. 88(4) Extended intervals between scheduled outages, shorter shutdown durations and dwindling maintenance budgets have increased the pulp and paper industry’s reliance on advanced wear protection technologies to lengthen conveyance equipment life and maintain production quality. The study introduced a thermal diffusion sealing treatment for arc-sprayed aluminum coating on S carbon steel. The sprayed aluminum-zinc duplex coating was heated to °C, so that the low-melting-point zinc could diffuse into the pores of the aluminum coating. Optical microscope, microhardness, electron probe microanalysis, and x-ray diffraction were used to evaluate the sealing .

During the transportation of natural resources (oil and gas) metal surface is exposed to flowing corrosive environment, in which, the mechanical process of metal removal through erosion and the electrochemical process of corrosion are coupled [1, 2, 3, 4].Here the observed mass loss is higher than the summation of mass loss due to pure erosion and pure corrosion.
Carbon steel is used in large amounts in the construction industry. By their nature of limited alloy content, usually less than 2% carbon of total weight, carbon steels are susceptible to very high corrosion rates in aggressive solutions and atmospheres [11,12].
The traditional surface passivation treatment for steel is obtained by conversion.

Erosion Corrosion • Erosion corrosion is the term used to describe corrosion that is accelerated as a result of an increase in the relative motion between the corrosive fluid and a metal wall. The process is usually a combination of chemical or electrochemical decomposition or dissolution and mechanical wear action.
Solution nitriding [4,5] of stainless steel parts at temperatures between K and K in to 0,3 MPa nitrogen atmosphere is being used to enrich the steel’s surface in a way similar to case hardening of carbon steels.
The nitrogen content achieved by this treatment may be very high, depending on solution nitriding temperatures and. Erosion Corrosion. Erosion corrosion is the increase in the rate of metal deterioration from abrasive effects.
However, if oxygen is present, the corrosion potential increases in the noble direction and the corrosion rate decreases significantly.

The composition of a commercial duplex stainless steel was modified with boron additions (,and wt.%) and processed by rapid-quenching techniques: Melt-spinning, copper-mold casting, and high-velocity oxygen fuel (HVOF). Spray deposition was also used to produce alloys as the process may induce rapid-solidified-like microstructures.
These processing routes led to microstructures. Carbon steel is composed of roughly 99 percent iron to 1 percent carbon, while cast iron normally contains 2 to 3 percent carbon and 97 to 98 percent iron.
Cast iron has more compressive strength, and carbon steel is more tensile. Carbon steel is. In this study, erosion–corrosion behavior of API pipeline steel has been assessed in 2 g l−1 NaCl solution purged with CO2 as the corrosive media and aluminum oxide as the erodent.

The effect of temperature on the corrosion of aluminum The Correlation Between Conductivity and Corrosion Potential of Solutions in Simulation of an Oil Field Environment [ E ] Observe and record the corrosive nature of oxidation-reduction reactions and determine the electro-chemical series of.
Aqueous corrosion requires a liquid that can form ions. Residual water and other liquids that ionize and are not fully drained from equipment during shutdowns present the potential for pitting, crevice and all forms of aqueous corrosion.
Attention to details of construction during initial design can minimize this issue. But inspectors should be. Carbon steel and stainless steels are some of the most common metals used in construction. Carbon steel is an alloy between carbon and iron. Also known as mild steel, carbon steel is one of the most commonly used engineering materials.
It is favored because it is relatively cheap and widely available. It also has good tensile strength and. Scale or deposits can build up in the well-bore tubulars and other down-hole components causing considerable damage to the well.
Infrastructure provides the supports for the well's system and with oil and gas consumption on the rise and transportation needed to feed the demand, all petroleum and pipeline engineers must have accurate corrosion and scaling information.
Copper corrosion is the corrosion of materials made of copper or copper alloys. When exposed to the atmosphere, copper oxidizes, causing bright copper surfaces to tarnish. After a few years, this tarnish gradually changes to dark brown or black, and finally to green.
Copper corrosion occurs at negligible rates in unpolluted air, water and. In view of the scientific and technical challenges as well as the considerable economic stakes (amounting to millions of U.S. dollars), this chapter focuses on the recent developments on the corrosion of steel by sulfidogenic anaerobes.
The corrosion layer is an active membrane where a looped interaction between the corrosion electrochemistry and the chemistry and transport of reactants and. The corrosion behaviour of S duplex and martensitic stainless steel was studied through weight loss and potentiodynamic polarization in 1–6 M HCl solutions.
Results show that S steel has significantly lower corrosion rates than steel from both tests at all concentrations with highest values of mm/y and mm/y in comparison to martensitic steel with corrosion.The flow rate of liquid chlorine through carbon steel pipework is restricted to 2 m/s to avoid removing the ferric chloride coating on the pipe surface which protects against erosion / corrosion of the carbon steel.
