Special Issue Information

Dear colleagues,

One of the greatest current concerns in surface engineering is the reduction in and/or inhibition of material deterioration in harsh working environments. Metallic materials are susceptible to specific atmospheres that can lead to great material losses due to corrosion in a wide range of applications and industrial sectors (materials processing, transportation, offshore technologies for renewable energy, aerospace, biomedicine, etc.). In fact, the costs of corrosion in developed countries are estimated to be around the 3–4% of GNP. The situation is considerably aggravated when mechanical solicitations are combined to create aggressive environments, which may involve a synergistic effect that results in unpredictable premature failures of materials and components. This is the case for tribocorrosion, which involves the simultaneous action of mechanical (wear) and electrochemical (corrosion) processes, resulting in a total material loss that is greater than the sum of the two processes taking place alone. This is a consequence of the damage caused to the passive layer (depassivation) under mechanical actions, resulting in the acceleration of corrosion, which, in turn, can lead to accelerated wear.

Tribocorrosion is a common degradation phenomenon in industry. In the last decade, a great effort has been made expand our knowledge of tribocorrosion mechanisms, as well as their inhibition or minimization through the use of coatings.

The scope of this Special Issue will serve as a forum for papers in the following areas:

  • The latest developments in test methods, considering the interplay between mechanical, chemical, and electrochemical interactions for the assessment of tribocorrosion;
  • Understanding the tribocorrosion mechanisms of metallic alloys and coatings;
  • Theoretical and experimental research, knowledge, and new ideas in the field of protective coatings and surface treatments for protection against tribocorrosion;
  • Computer modelling and simulation to predict the performances of materials and/or protective coatings under tribocorrosion working conditions.

SAE 5160 steel, classified as high-strength, low-alloy steel, is widely used in the automotive sector due to its excellent mechanical strength and ductility. However, its inherently low corrosion resistance limits its broader application. This study explores the application of the cathodic cage plasma deposition (CCPD) technique to enhance the corrosion resistance of SAE 5160 steel. The treatment was performed using a Hastelloy cathodic cage under two atmospheric conditions: hydrogen-rich (75%H2/25%N2) and nitrogen-rich (25%H2/75%N2). Comprehensive analyses revealed significant improvements in surface properties and corrosion resistance. The hydrogen-rich condition (H25N) facilitated the formation of Cr0.4Ni0.6 and CrN phases, associated with a nanocrystalline structure (37.6 nm) and a thicker coating (45.5 μm), resulting in polarization resistance over 290 times greater than that of untreated steel. Conversely, nitrogen-rich treatment (H75N) promoted the formation of Fe3N and Fe4N phases, achieving a dense but thinner layer (19.6 μm) with polarization resistance approximately 20 times higher than that of untreated steel. These findings underscore the effectiveness of CCPD as a versatile and scalable surface engineering technique capable of tailoring the properties of SAE 5160 steel for use in highly corrosive environments. This study highlights the critical role of optimizing gas compositions and treatment parameters, offering a foundation for advancing plasma-assisted technologies and alloying strategies. The results provide a valuable framework for developing next-generation corrosion-resistant materials, promoting the longevity and reliability of high-strength steels in demanding industrial applications.

The objective is to address the issue of gas-carrying particles generated by erosion wear problems in the transportation process of gas storage reservoir pipelines. In accordance with the principles of the multiphase flow theory, the particle discrete phase model, high temperature, high pressure, water volume fraction, and other pertinent factors, this paper presents a three-phase gas–liquid–solid erosion mathematical model of a three-way gas storage reservoir. The effects of temperature, pressure, water content volume fraction, gas extraction, particle mass flow rate, and particle size on the tee’s erosion location and erosion rate were investigated based on this model. The findings indicate that, as the pressure and temperature decline, the maximum erosion rate of the tee exhibits a decreasing trend. Gas storage reservoir water production is relatively low, and its maximum erosion rate of the tee exerts a negligible influence. Conversely, the maximum erosion rate of the tee is significantly influenced by the gas extraction rate, exhibiting an exponential relationship with the maximum erosion rate and the rate of gas extraction. It was observed that, when the volume of gas extracted exceeded 70 × 104 m3/d, the maximum erosion rate of the tee exceeded the critical erosion rate of 0.076 mm/a. The maximum erosion rate of the tee caused by the sand mass flow rate remained relatively constant. However, the maximum erosion rate of the tee exhibited a linear correlation with the salt mass flow rate and the maximum erosion rate. The maximum erosion rate of the tee is greater than the critical erosion rate of 0.076 mm/a when the gas extraction volume is greater than 37.3 × 104 m3/d and the salt mass flow rate is greater than approximately 25 kg/d. As the sand and salt particle sizes increase, the maximum erosion rate of the tee initially rises, then declines, and finally stabilizes. The findings of this study offer valuable insights into the mechanisms governing tee erosion under elevated temperatures and pressures within storage reservoirs. Full article
