“…Reciprocating pin-on-plate wear tests have been previously conducted using 7.94 mm diameter cemented carbide (WC-6Co) and alumina (99.5 per cent) balls on a range of Cr-based and stainless steel-based coatings on AISI 316L substrates [14][15][16][17][18]. These coatings were investigated as a means of improving the limited tribo-corrosion resistance of the stainless steel.…”

The most worrisome failure for coated surfaces in tribological contacts is premature coating detachment (adhesive failure). This article presents, by way of case studies, attempts to understand such failures encountered in tribological testing of coated components. Numerical modelling has been used to help understand what stresses at the coating-substrate interface are most detrimental to long interface lifetimes.

“…The increased use of SS films in diverse technological areas has been driven by their magnetic properties 5,6 , electrical properties 7,8 , corrosion resistance 2,3,9 , biocompatibility performance 10 , and surface reflective properties [11][12][13] . Aldrich-Smith et al 19 compared the antiwear performance of SS films with typical CrN tribological films, and saw that sputtered SS films are neither intrinsically anti-scratch nor antiwear materials. However, at different structural applications, moderate capacity of bearing contact loads is essential for avoiding in-service film degradation.…”

UNS S31603 stainless steel (SS) substrates were covered by reactive magnetron-sputtering with protective SS coatings of the same steel specification. A mechanical characterization study (through nano-, micro-and macro-hardness tests) of samples obtained under two different sputtering conditions and varying the N 2 gas flow rate was carried out. This contribution aimed at appraising the effects of varying the nitrogen flow rate on hardness, elastic modulus, and susceptibility to indentation-induced crack formation of the coated SSs. Nitrogen-free samples displayed body-centered cubic (BCC) films with 9.0-9.4 GPa hardness and 203-206 GPa elastic modulus, while their susceptibility to indentation-induced cracking varied between superior and moderated among the two sets of sputtering conditions studied. Samples alloyed with 4-6 N at-% displayed a predominantly face-centered cubic (FCC) structure, 9.4 GPa hardness, 196-218 GPa elastic modulus, and superior resistance to crack formation. Samples with 11.5-22.0 N at-% were fully composed of the FCC structure, displayed 12.4-15.2 GPa hardness, 188-193 GPa elastic modulus, and moderated resistance to indentation-induced crack formation. Samples with 47.0 N at-% displayed FCC compound nitride structure, for which hardness and elastic modulus were 8.1 GPa and 139 GPa, respectively. These samples displayed low resistance to crack formation.

“…Indeed, many efforts have been made to improve the tribocorrosion performance of biodemical alloys by surface coatings, including diamond‐like carbon coatings, ion implantation, TiN and TiC based coatings, CrN based coatings and surface alloying . In particular, detailed studies have been performed on the potential of S‐phase coating and CrN coating to improve the tribocorrosion behavior of biomedical alloys .…”

Response of duplex Cr(N)/S and Cr(C)/S coatings on 316L stainless steel to tribocorrosion in 0.89% NaCl solution under plastic contact conditions

Two duplex coatings, Cr(N)/S and Cr(C)/S, were deposited on 316L stainless steel by magnetron sputtering. The effectiveness of these duplex coatings in improving the tribocorrosion behaviour of medical alloys under elastic contact conditions has been demonstrated in a recent publication. The present work focused on the response of these duplex coatings to tribocorrosion under plastic contact conditions. Tribocorrosion tests were conducted in 0.89 % NaCl solution at 37 o C at an initial contact pressure of 740 MPa and under unidirectional sliding conditions for sliding duration up to 24 h. The results showed that during sliding in the corrosive solution, the duplex coatings were plastically deformed into the substrate to a depth about 1 m. The Cr(C)/S duplex coating had sufficient ductility to accommodate the deformation without cracking, such that it was worn through gradually, leading to the gradual increase in open circuit potential (OCP) and coefficient of friction (COF). On the other hand, the Cr(N)/S duplex coating suffered from cracking at all tested potentials, leading to coating blistering after prolonged sliding at OCP and stable pit formation in the substrate beneath the coating at applied anodic potentials.
