“…More importantly, however, this process, known as oxidative wear, produces metal ions into the local environment (8,13,14). Under more severe contact wear situations, metal fretting can result, producing micron-sized metal debris in addition to metal ions (15)(16)(17)(18)(19)(20). When the contacting metals are dissimilar, or when a conductor such as carbon is used, a galvanic corrosion response can further accelerate the production of metal ions (21,22).…”

Wear‐Resistant, Hemocompatible Ti‐Nb‐Zr and Zr‐Nb Alloys to Improve Blood Pump Design and Performance

Over the past several years, we have developed novel titanium-niobium-zirconium (Ti-Nb-Zr) alloys to address the long-term performance needs of orthopedic implants. The unique properties of these alloys also render them promising candidates for blood pumps. These properties include excellent biocompatibility in combination with high strength and toughness, and low elastic modulus (low stiffness). Additionally, these metal alloys are readily hot or cold worked into complex shapes including wire, foil, tubing and bar. They are readily machined and polished, and they can be surface oxidized to form a hard, wear-resistant, low-friction ceramic surface layer. In this diffusion-hardened condition, oxygen also hardens the underlying metal to optimize the bone between the ceramic oxide surface and the tough metal substrate. Unlike metal surfaces, oxidative wear, which can alter surface energy, friction, and hemocompatibility, does not occur. Consequently, the combined benefits of a stable, wear-resistant, low-friction ceramic surface layer with the toughness, strength, formability, and thermal conductivity of metal may provide improvements in the design and performance of blood pumps and peripheral graft and percutaneous (power) components of the pump.

“…Some researchers reported that the lubricating effect of seawater was better than distilled water, so under the lubrication of seawater, a lower coefficient of friction was present . However, the influence of seawater on the wear of metals is much more significant than that on friction behaviour, because under most circumstances, this liquid will give rise to a corrosion process which accounts for high wear rate and ultimately for increasing coefficient of friction through the accumulation of trapped corrosion debris . More than that, pitting corrosion may be induced by mechanical attacks , and Burstein argued this induced effect arising both from the exposure of fresh active sites and from the altering of their geometry.…”

Tribocorrosion is often complicated and harmful to metallic components, which depends on the mechanics of the tribological contact, on the electrochemical characters, on the properties of the contacting materials, and on the physico‐chemical properties of the environment. In this work, effects of corrosive media on the friction and wear behaviour, on the corrosion behaviour and on the synergistic effect between them were investigated in detail on a pin‐on‐disc tribometer. Although no electrochemical corrosion occurs in distilled water, its lubricity is so bad that plastic ratchetting effect and abrasive wear are observed on 304SS surface which result in severe material loss. In other three simulated seawater, corrosion and wear interact positively, making the pure mechanical wear and corrosion accelerated wear including abrasion and delamination, be the main reasons for 304SS degradation. Note that solution pH also plays an important role in determining material degradation.

“…Due to their construction and application, wire ropes are prone to fretting damages 1,2 : as tensile loads are applied and released, or the rope runs over sheaves, the contact pressure between individual wires changes and they are subjected to oscillatory motion. The contact pressure and amplitude of the oscillatory motion depends not only on the working conditions, but also on the rope construction: linear contacts (typical between wires of the same layer) can be subjected to fretting and decrease the fatigue life of the rope.…”

“…6,7 This is the case studied in this paper, where high level of wear ( Figure 2) and the presence of wear debris were observed. The fretting behaviour of different wires were studied by several authors: fretting tests accomplished in seawater and in air with wires 5 mm in diameter 1 ; fretting tests with wires 3.4 mm in diameter and with different surface coatings 8 ; fretting tests with bright (as drawn) wires 2.8 mm in diameter in dry conditions and with low viscosity oils [9][10][11] ; and fretting tests with wires 1 mm in diameter. 12 However, all these tests were carried out with quite manageable diameters.…”

Laboratory fretting tests with thin wire specimens

Wire ropes, due to their construction and application, are prone to fretting damages. In order to know the wear behaviour of individual wires under fretting conditions, laboratory tests are required. The present work describes the preliminary fretting tests accomplished with thin steel wires to optimise the testing procedure. The tests were carried out with 'crossed-cylinders' configuration varying the stroke and normal load. Afterwards, the fretted surfaces were characterised by means of an optical and scanning electron microscope, and a diamond stylus. No significant influence of selected parameters was detected and a good correlation was proved for on-line measured parameters and off-line obtained values.
