“…Hamelynck et al found a huge reduction of Cr ion release from CoCrMo hip component due to TiNbN coating deposited by physical vapour deposition [8]. Recently, Coatings 2021, 11, 867 2 of 12 the reduction of Co, Cr, and Mo ion release from CoCrMo knee implant has been achieved by depositing CrN/NbN nanoscale multilayer structured coatings by high power impulse magnetron sputtering (HIPIMS) [9]. To the best of the authors' knowledge, the literature available on the surface engineering of CoCrMo alloys by HIPIMS is scarce.…”

This study describes the performance of nanoscale multilayer TiN/NbN coatings deposited on CoCrMo medical-grade alloys by utilising novel mixed high power impulse magnetron sputtering (HIPIMS) and direct current unbalanced magnetron sputtering (UBM) technique in an industrial size vacuum coater. Scanning electron microscopy analysis showed that these coatings were extremely dense without any intercolumnar voids. The coating exhibited high hardness of 28 GPa, as well as low friction and wear coefficient of 0.7 and 1.4 × 10−14 m3·N−1·m−1, respectively, as compared to the bare material. Scratch tests revealed superior coating to substrate adhesion due to the HIPIMS etching prior to coating deposition. Energy-dispersive X-ray analysis of the wear debris generated during the impact test together with focused ion beam cross-section analysis in different locations of the impact crater revealed the coating failure mechanism and further confirmed the excellent coating to substrate bonding strength. Potentiodynamic polarisation tests in NaCl and Hank’s solutions revealed the clear passivation behaviour, several orders of magnitude lower corrosion currents, and high pitting potentials of the coating, which guarantee excellent protection to the base alloy in such aggressive environments. Inductively coupled plasma mass spectrometry analysis of Hank’s solution containing corrosion debris of the coated sample revealed that the leaching of harmful metal ions from the base material was reduced to below the detection limit of the technique, thus demonstrating the high barrier properties of the coating.

Wear resistance, which is one of the main technological quality features of machine parts and tools, is determined by the properties of their surface layer. The demand for high-quality products forces manufacturers to use modern structural and tooling materials as well as efficient and cost-effective methods of their treatment. The paper presents the results of research on selected properties of tools made of tool steels and sintered carbides, as well as parts made of aluminum alloy subjected to selected surface treatment processes, such as mechanical (grinding, turning, milling, burnishing) and thermo-chemical (nitriding, sulfonitriding) processes, and physical vapor deposition (PVD) of coatings. The presented results, including analyses of the surface geometric structure, microstructure, and microhardness, as well as tribological and machining properties of selected materials, indicate the possibility of improving the functional quality of tools and machine parts.

“…In all groups, cast cobalt chrome (CoCr) femoral heads and monobloc CoCr acetabular cups were manufactured by Mat Ortho Ltd (Leatherhead, Kent, United Kingdom). The femoral heads and acetabular shells used in the SLC‐MoM group were coated by Zimmer‐Biomet Ltd (Swindon, United Kingdom), where a 5 μm multilayered CrN/NbN superlattice‐structured ceramic coating was applied using High Power Impulse Magnetron Sputtering technology (HIPIMS) (HTC 1000‐4, four cathode system (Hauzer Techno Coatings, Europe B.V. Venlo, The Netherlands) that provided a highly dense, hard and adherent coating on the bearing surface . The superlattice structure consisted of repeating CrN and NbN layers and the advantage of applying a nano‐layered, inhomogenous columnar shaped crystal structure is that the hardness values of the coating is improved combined with excellent corrosion behavior due to the presence of the highly electrochemically stable niobium as a partner material.…”

“…A chromium nitride/niobium nitride (CrN/NbN) coating utilizing a nanoscale multilayer/superlattice (SLC) structure was applied onto CoCr bearing surfaces to increase hardness, wear and corrosion resistance. A high power impulse magnetron sputtering technology deposited dense and adherent coatings onto the bearing surfaces and the aim of the study was to use an animal model to investigate the performance of coated MoM bearings compared with non‐coated MoM and MoP bearing combinations. Our hypothesis was that a SLC applied to the femoral head and acetabular cup surface would result in a reduction in volumetric wear, a decrease in blood chromium and cobalt ion levels and reduce any potential adverse reactions to metal debris (ARMD).…”

An ovine total hip arthroplasty model was developed to evaluate metal ion release, wear, the biological response and adverse tissue reaction to metal-on-metal (MoM) bearing materials. The performance of an advanced superlattice ceramic coating (SLC) was evaluated as a bearing surface and experimental groups divided into; (1) MoM articulating surfaces coated with a SLC coating (SLC-MoM), (2) uncoated MoM surfaces (MoM), and (3) metal on polyethylene (MoP) surfaces. Implants remained in vivo for 13 months and blood chromium (Cr) and cobalt (Co) metal ion levels were measured pre and postoperatively. Synovial tissue was graded using an ALVAL scoring system. When compared with the MoM group, sheep with SLC-MoM implants showed significantly lower levels of chromium and cobalt metal ions within blood over the 13-month period. Evidence of gray tissue staining was observed in the synovium of implants in the MOM group. A significantly lower ALVAL score was measured in the SLC-MoM group (3.88) when compared with MoM components (6.67) (p = 0.010). ALVAL results showed no significant difference when SLC-MOM components were compared to MoP (5.25). This model was able to distinguish wear and the effect of released debris between different bearing combinations and demonstrated the effect of a SLC coating when applied onto the bearing surface.
