“…This structure results in an exceptional combination of strength, ductility, wear resistance [2,3] and impact resistance [4,5]. The austempering heat treatment converts ductile iron into ADI, bringing about excellent strength, toughness and fatigue characteristics [6][7][8][9][10][11][12][13][14][15]. This heat treatment cycle involves two steps.…”

“…However, studies about PVD coatings applied to ADI are very scarce. All existing references correspond to a single research group and do not reach a dozen [11][12][13][14][15][16][17][18][19][20]. Besides, the results obtained on other metal substrates cannot be forwardly extended to ADI because of the presence of the graphite nodules on ADI microstructure.…”

This work studied the sliding wear performance of TiAl-based nitride coatings synthesized on austempered ductile iron (ADI) by cathodic arc deposition (CAD) and plasma-based ion implantation and deposition (PBIID). Monolayer CAD TiAlN films and bilayer CAD and PBIID TiAl/TiAlN films deposited on an experimental device were analyzed and benchmarked against a commercial bilayer CAD film. Sliding wear was evaluated in a pin-on-disc tribometer. Two test conditions were employed, one intended to prevent damage (low load, short distance) and another intended to promote damage (higher load, longer distance). Regarding low load tests, all coated samples showed friction coefficients of 0.40-0.45 and negligible wear. Regarding high load tests, all coated variants exhibited lower or equal disc and pin wear rates with respect to uncoated ADI. In addition, coated samples displayed steady-state friction coefficients between 0.2 and 0.6 while uncoated ADI steady-state coefficients between 0.6 and 0.85.

Ti-6Al-4V material is generally used in biomaterial applications. However, this material is difficult to supply and an expensive material. Instead of Ti-6Al-4V material; It is investigated whether the use of 316 L material as an alternative is easier and more economical. In this study, Ti-6Al-4V and AISI 316 L test specimens made of the material subjected to the test under the same conditions wear performance were investigated using the ball on disc experimental setup. The experiments were carried out in three replicates in a dry and liquid medium. As a result, in the experiments; AISI 316 L samples are coated with PVD method compared to other samples in wear rates and abrasive wear marks on the surface of the samples were found to decrease. In studies using sodium hyaluronate fluid, it was found that the rate of abrasion and wear traces decreased compared to the dry environment. It was determined that 316 L samples coated with PVD method showed better wear performance compared to uncoated Ti-6Al-4V material. Considering the density differences of Ti6Al4V and 316L materials, 316L can be used instead of Ti6Al4V material.
