Comparative tribological study of chromium coatings with different specific hardness

Tribological and electrochemical behavior of thick Cr–C alloy coatings electrodeposited in trivalent chromium bath as an alternative to conventional Cr coatings

“…Nowadays, some researchers [17][18][19][20] expressed the wear behavior with elastic modulus (E) and hardness (H). High H/E ratio generally implies excellent fracture toughness [21] and good wear resistance [16]. Enlightened by the literature studies [17][18][19][20], in this study, the E and H/E ratio were also estimated by nano-indentation investigation as shown in Table 2.…”

Mechanical and tribological properties of CrN/Ag and CrSiN/Ag nanoscale multilayers

“…This slight decrease could be attributed to the solid lubrication provided by silver in the films. In fact, during the friction tests wear debris (in our case mainly composed of silver) remains in the track [20] and contributes to the lubrication and to the decrease in the friction coefficient. The lowest friction coefficient is observed for the CrN/Ag multilayer having the largest thickness of CrN nanolayer.…”

Tribological characteristics and cutting performance of Crx%C-coated carbide tools

“…Recent research on chromium carbides coatings emphasized its oxidative and corrosive resistance. Some studies showed that chromium carbides with superior hardness, adhesion strength and wear resistance demonstrate great potential for replacing electroplated hard chrome as mold protection [3][4][5][6][7]. Applications of chromium carbide on working tools are rapidly increasing in commercial products.…”
