Mechanical Properties of Materials and Their Erosive Wear

Abstract

In this paper, the authors analyse the impact of selected mechanical properties of materials on their erosive wear caused by a steady stream of solid particles. A wear process is a function of the material properties of two materials that interact with each other in a given environment, i.e. the construction material and the particles that cause erosion. Erosive losses occur upon reaching a critical condition of damaging an element of the material’s surface under the influence of kinetic energy that result from incident particles of an abrasive material. It is proposed that the critical condition that accompanies the formation of erosion losses should be represented by the toughness (U) and the specific work of the deformation of the sample in the tensile strength test (W). The study involved the following materials: NC6, 42CrMo4, 20MnCr5, and S235JR.

“…As the consequence of the influence of particles carried by a stream of air or liquid, a surface degradation occurs. It is much bigger and more irregular than that the degradation resulting from other wear mechanisms [10]. Additionally, the eroded area may cause a disturbed medium flow.…”

“…It is also used in quality control of microprocessor and solar panel surface manufacturing. In the area of technology and utilization research the aforementioned technique is used to determine the wear of cutting tools and to examine the condition of the surface after abrasion and corrosion tests [9][10][11]13]. As can be readily seen, there are no results showing its application in the assessment of the condition of surface layers of materials subjected to erosion.…”

“…Erosive wear is a process occurring in many industries [10,11,14]. We can encounter it in pneumatic transport systems, air ducts, jet engine blades, mills, fans, and many other systems [11,12,14].…”
