Corrosion and tribological properties and impact fatigue behaviors of TiN- and DLC-coated stainless steels in a simulated body fluid environment

Surface Modification of AISI 440B Stainless Steel and its Influence on Surgical Drill Bits Performance

“…Unlike the reference material, DLC-and TiN-modified samples showed no measurable wear during the test. However, it should be noted that in the literature, cases of TiN fatigue cracking and spalling from martensitic stainless steels are described [11]. …”

“…Nevertheless, the use of ferrous alloys in medical applications is still a concern due to their questionable corrosion and wear resistance. To extend their biocompatibility, improve stability in variable environmental conditions, improve ease of handling, and maximize their performance, diffusion layers and coatings are applied to the surface [8,9] Both diamondlike carbon (DLC) and titanium nitride (TiN) coatings are considered to be promising surface modification techniques in biomedical applications [10][11][12][13].…”

“…DLC coatings are believed to be biocompatible with the human body [10,14], chemically inert [10], and corrosion [11,15] and wear [14,16,17] resistant. A number of studies describe the effect of DLC application in industry and above all in medicine positively [16,18].…”

Effect of Ultrasonic Surface Impact on the Fatigue Behavior of Ti-6Al-4V Subject to Simulated Body Fluid

“…Liu et al [33] studied the HCF behavior of TC4 in simulated body fluid (SBF), the endurance limit at 1 × 10 8 cycles of TC4 decreases by 7%. The fatigue properties of magnesium alloy [34,35], ZrCuFeAlAg bulk metallic glass [36], niobium alloy [37], stainless steel [38], TiN-and DLC-coated stainless steel [39] in simulated body fluid have been studied in the recent five years. Bai et al [40], Huang et al [41], and Li et al [42,43] reported that nanocrystal surface layers by SSN are conducive to the corrosion resistance, because of the high density grain boundaries and the deeper passive film.…”

A comparative study of the corrosion performance of titanium (Ti), titanium nitride (TiN), titanium dioxide (TiO2) and nitrogen-doped titanium oxides (N–TiO2), as coatings for biomedical applications

“…These issues must be addressed because preventing early failure of implants caused by corrosion is crucial. Recent methods with considerable potential include the deposition of a protective ceramic coating (e.g., TiN, DLC, TiAlN, TiN/TiAlN, TaN, and ZrN coatings) on the metal surface [5][6][7][8][9][10][11][12][13][14].…”
