“…3.1). As previously reported 31 , 44 , the carbide content influences the width and depth of the wear track as well as the micro-abrasive wear mechanisms. However, the carbide content was insufficient to protect the matrix at 10 N, resulting an increase in the wear rate.…”

“…A ball-on-plate tribometer (Bruker Universal Mechanical Tester Tribolab, USA) was employed to perform dry reciprocating wear tests, with a configuration detailed elsewhere 31 . The test parameters were as follows: 3 N load, 1 Hz frequency, 3 mm stroke for 1 h according to ASTM G133-05 standard 32 .…”

The dry sliding wear behaviour of a high carbon martensitic stainless steel (HCMSS) consisting of ~ 22.5 vol% of chromium (Cr)- and vanadium (V)-rich carbides processed by electron beam melting (EBM) has been captured. The microstructure consisted of martensite and retained austenite phases with a homogeneous distribution of sub-micron-sized V-rich and micron-sized Cr-rich carbides, leading to relatively high hardness. The CoF decreased ~ 14.1% with increasing load in the steady-state, due to the material transferred from the wear track over the counterbody. The wear rate of the HCMSS compared to martensitic tool steel processed in the same manner, and it was nearly identical under low applied load. The dominant wear mechanism was removal of the steel matrix through abrasion, followed by the oxidation of the wear track, while three-body abrasive wear occurred with increasing load. A plastically deformed zone beneath the wear track was revealed through cross-sectional hardness mapping. Specific phenomena occurred with increasingly aggressive wear conditions were described with carbide cracking, pull-out of V-rich carbides and matrix cracking. This study revealed the wear performance of the additively manufactured HCMSS, which could pave the way for producing components for wear-related applications ranging from shafts to plastic injection moulds via EBM.

“…The oxygen content is significantly higher than that of the matrix. [31,32] The friction form of 17Cr2Ni2MoVNb steel was mainly of oxidation wear and abrasive wear, while 20Cr2Ni4A steel contained severe adhesive wear, abrasive wear, oxidation wear and a small amount of stress fatigue wear [33][34][35][36][37].…”

The effects of cryogenic treatment and low temperature tempering on the microstructure, mechanical properties and distortion of the 20Cr2Ni4A and 17Cr2Ni2MoVNb carburized gear steels were investigated. The results showed that the case hardness of the experimental steels was increased after the cryogenic treatment, due to the decrease of the retained austenite content and the precipitation of the tiny carbides. The wear resistance of the two steels after cryogenic treatment was improved, although the wear mechanisms were different for 17Cr2Ni2MoVNb and 20Cr2Ni4A steels. The distortion of the Navy C-ring specimens underwent shrinkage before expansion during the cryogenic process, and the distortion of 17Cr2Ni2MoVNb steel was smaller than that of 20Cr2Ni4A steel.

“…It is well known that the tribological behaviour of steels is influenced by their microstructure, particularly the size and the distribution of the hard phases, typically carbides [11][12][13][14][15]. Karlsson et al [16,17] showed that fine carbides, homogenously distributed into the matrix, typically enhance the wear performance of stainless and tool steels.…”
