Effect of cathodic arc PVD parameters on roughness of TiN coating on steel substrate

In Vitro Analysis of the Efficacy of Ultrasonic Scalers and a Toothbrush for Removing Bacteria from Resorbable Blast Material Titanium Disks

“…Roughness average (R a ) is one of the most widely used surface parameters. 23 R z (the arithmetic mean of the positive predominant crest and the analog absolute value of the negative crests) is also one of the most frequently used roughness parameters in the industry. 24 There are some limitations, given that R a averages all peaks and valleys of the roughness profile, which neutralizes some outlying points.…”

Wear behavior of γ-irradiated Ti6Al4V alloy sliding on TiN deposited steel surface

“…The SEM morphology of the TiN surface (Figure 2 (a)) shows the dense arc deposition with the smaller voids and macro droplets due to the high velocity of the Ti particle from the cathode [25]. The difference in the droplet phase of the TiN deposited surface was caused by the nitrogen flow rate and coating roughness parameter [26].…”

Tribological performance of TiN coatings deposited on 304L stainless steel used for olive-oil extraction

“…In the same context, Grun [17] reported in his study that a good adhesion for coatings could be obtained when using pulse bias. Ali et al [18] studied the effects of substrate bias; temperature, nitrogen flow rate, and metal ion etching in surface roughness mainly depend on the conditions of sample preparation, surface treatment and other parameters. Akkaya et al [19] have shown in their study the effects of pulse bias in structure and mechanical properties of TiN coatings, that i) the crystal prefers orientation changing from (111) to (220) accompanied by structural transition and ii) there is significant improvement of tribological properties with the application of pulse bias.…”
