Tribological behavior of DLC-coated articulating joint implants

Diamond like carbon coatings for potential application in biological implants—a review

“…Thorwarth et al [49] used a spine disk simulator and compared a DLC (a-C:H) with various surface finishes against another DLC coated surface and compared them to uncoated CoCrMo coupling of similar surface roughness, at a high loading of 1200 N in bovine serum. Although for hips this is not high, it is for a spine disk.…”

“…Out of 14 reports [4,27,[39][40][41][42][43][44][45][46][47][48][49][50] there appeared to be no standardisation between choice of testing conditions and counter surface.…”

Tribocorrosion behavior and ions release of CoCrMo alloy coated with a TiAlVCN/CN multilayer in simulated body fluid plus bovine serum albumin

“…But DLC coatings have shown a sudden failure of layers whose interfaces are too weak with respect to the stress-corrosion cracking mechanism [14]. Amorphous carbon (a-C) films have shown a poor adhesion to the substrates, which is caused mainly by high residual stresses in film and high diffusion of carbon into the substrate (i.e.…”

Application of Low-Temperature Plasma Processes for Biomaterials

“…Particularly for implants where inertness of the surface is required, they are therefore an attractive option for coating of medical implants in a number of applications in reconstructive surgery and dentistry (Roy & Lee, 2007). Diamond-like carbon coatings have for example been examined for ureteral stents (Laube et al, 2007), orthodontic archwires (Kobayashi et al, 2007), joint implants (Thorwarth et al, 2010) or cardiovascular stents (De Scheerder et al, 2000).…”
