Comparisons of the two-body abrasive wear behaviour of four different ferrous microstructures with similar hardness levels

Effect of microstructure on the abrasive wear resistance of steels with hardness 450 HV

“…Increasing the surface hardness leads to improved wear resistance within the same microstructure, but different microstructures might show very different wear behavior for a given hardness level [1]. A comparison of bainite, pearlite martensite and tempered martensite with similar hardness level (350HV) revealed that multiphase microstructures might show better wear resistance [2]. Commercial 400 HB wear resistant steels also showed different wear behavior in high-stress abrasive testing despite the same hardness grade [3].…”

Comparison of three-body impact abrasive wear behaviors for quenching–partitioning–tempering and quenching–tempering 20Si2Ni3 steels

“…Typical wear may be divided into five categories as: abrasive, erosive, adhesive, chemical and fretting wear [5]. Abrasive wear mainly exists in the transportation, mining and mineral processing industries [5][6][7][8]. The surfaces of components are damaged by heavy impacts and scratching of hard abrasives trapped between the contacting surfaces during the wear.…”

Effect of Welding Parameters on Nanostructured Fe-(C, B)-(Cr, Nb) Alloys

“…Niobium carbides had not affected on wear resistance because their size was much smaller than the silicon carbide and they were torn off together with the matrix as shown in figures 8 a and c. In Figure 8d it can be seen how the damage on the surface had increased, the SiC penetrated being embedded in the welded material. This would be related to the higher presence of α−Fe as inter-network phase 30 indicated in figure 3.…”

“…The samples with low heat input (L7) formed by eutectic structure with dendrites inter-network of α−Fe phased didn't shown scratch resistance producing an excessive plastic deformation and weight loss. However, when matrix consisted on eutectic carboborides with cluster of α-Fe or needles of M 7 BC 3 (L3) there was observed resistance to cutting and lower ductility at the matrix-carboboride interface which produced the beginning of failure 30 .…”
