Special Issue Information

Dear Colleagues,

We would like to invite you to submit your work to this Special Issue, “Surface Treatment of Metals II”. The present additional Special Issue is a result of a successful first Issue. The new Issue has a similar focus on surface treatment solutions applied for metallic materials which are cost effective, energy efficient, and safe for operators and the environment. The aim of this Special Issue is to present the latest experimental and theoretical achievements in the field, through a combination of original research papers and review articles from leading research groups around the world. Scientific and technological progress has been achieved on this topic by universities and research institutes worldwide. Further, surface coating is very well known by scientists and can improve the properties of any kind of metallic material.

In particular, the topics of interest include but are not limited to:

  • Mechanical coating/alloying/treatment of metals.
  • Thermal/chemical treatment of metals.
  • Nonconventional treatment applied to metals, such as thermo/mechanical coating, including removal of heavy metals from industrial waste; electrochemical machining; abrasive flow machining; shot blasting; shot peening; turbo-abrasive machining; centrifugal barreling finish; centrifugal isotropic finishing; etc.
  • Biomaterial coatings applied to Ti-based alloys, CoCr alloys, and stainless steels, among others.

The relevance of this study lies in the need to research the wear process of the elements of dynamic systems and to establish the dependence of the geometric and structural characteristics of wheels restored by plasma surfacing with a coating of 15Cr17Ni12V3F on dynamic, cyclically varying loads. The study was aimed to establish the dependencies between the deviation of the wear area, the formation of contact and fatigue stresses, and the change in the phase structure of the wheel defect. It is important to justify the permissible limits of wear of the transverse profile in the contact zone of a wheel and ridge. The object of the study was the dynamic interaction of the “wheel–ridge–rail contact surface” system. To achieve the goal, the following methodology was adopted: kinematic analysis, strength calculation, the use of mathematical analysis in dynamic system modelling, virtual modelling in the SOLIDWORKS software environment of the GearTrax application, experiment planning, and model correction through the results of metallographic studies. The results of the study are presented as reasonable prediction criteria that consider contact cycles during the formation of fatigue stresses at the stage of defect origin. The process of the dynamic interaction of the contact worn profile of a wheel with a railway rail is explored. Polynomial equations are proposed to substantiate the optimal design and technological parameters of designing a railway carriage wheel. The permissible limits of wear of the transverse profile in the contact zone of the wheel and the ridge are justified while taking the coefficient of the reduction of contact stresses in the metal into account. The dependences of the change in static load on the utilization factor of the railway carriage load capacity are established. The dependences of changes in fatigue stresses on the design deviation of the contact area of wheel wear are established. It is confirmed that the stress concentration under cyclic loads is formed in the ferritic layers of the material structure before the appearance of wear. Full article
