In this study, air-blast shot peening was applied to analyze the wear characteristics of CP titanium (Grade II). The specimens were exposed to different plastic-deformation rates via different severe shot-peening conditions in order to determine the wear behaviour of CP titanium. A free-ball micro-abrasion test was performed on the specimens shot peened with different Almen intensities. Nanohardness measurements were also performed to investigate the work-hardened layer -the coarse-grainedstructure transition zone. Light microscopy and scanning electron microscopy (SEM) were used to analyze both the wear tracks and the severely deformed layer. As a result, the plastically deformed layer thickness reaches approximately 100 μm beneath the surface. Moreover, the hardness and wear durability after severe shot peening is increased. Keywords: air-blast shot peening, wear, nanoindentation, plastic deformation, ultra-fine-grain durability V tej {tudiji je bilo uporabljeno peskanje z zrakom za {tudij lastnosti pri obrabi CP-titana (Grade II). Vzorci so bili izpostavljeni razli~nim stopnjam deformacije v razli~nih razmerah peskanja, da bi ugotovili vedenje CP-titana pri obrabi. Izvr{en je bil abrazijski preizkus z mikrokroglicami na vzorcih po peskanju z razli~no Almen-intenziteto. Izvr{ene so bile meritve nanotrdote za preiskavo utrjenega sloja in grobozrnate strukture prehodne cone. Za analizo sledov obrabe in mo~no deformiranih slojev sta bili uporabljeni svetlobna in vrsti~na elektronska mikroskopija (SEM). Debelina plasti~no deformiranega sloja dose`e globino okrog 100 μm pod povr{ino. Trdota in odpornost proti obrabi se po mo~nem peskanju pove~ata. Klju~ne besede: hladno kovanje povr{ine s peskanjem z zrakom, obraba, nanoodtisek, plasti~na deformacija, odpornost ultra drobnih zrn

Gradient nanostructures (GNSs) have been optimized in recent years for desired performance. The diffusion behavior in GNS metals is crucial for understanding the diffusion mechanism and relative characteristics of different interfaces that provide fundamental understanding for advancing the traditional surface alloying processes. In this paper, atomic diffusion, reactive diffusion, and surface alloying processes are reviewed for various metals with a preformed GNS surface layer. We emphasize the promoted atomic diffusion and reactive diffusion in the GNS surface layer that are related to a higher interfacial energy state with respect to those in relaxed coarse-grained samples. Accordingly, different surface alloying processes, such as nitriding and chromizing, have been modified significantly, and some diffusion-related properties have been enhanced. Finally, the perspectives on current research in this field are discussed.

“…Plasma nitriding has been proposed as a possibility for improving the surface properties 17 . Plasma nitriding of titanium alloys results in a thin composed layer of titanium nitrides, and a nitrogen diffusion zone 18 . Titanium nitride has been successfully used as coating materials due to their tribological properties, biocompatibility and affordable price 19 .…”

In recent years, intensive development of dentistry stimulates the demand for new titanium implant materials created by surface engineering. Plasma nitriding is proposed as a solution to improve the biocompatibility. This work investigated the influence of plasma carbonitriding on the roughness and contact angle of Ti6Al4V treated in a Ar / N 2 / CH 4 plasma for 3 h and 6 h at 600 °C. The characterization was made by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Theta Lite Optical Tensiometer, and laser confocal microscopy. The XRD results indicated the formation of Ti 3 N 1.29 and Ti 2 N phase. It was observed that the surface roughness increases from 0.24 to 0.87 μm after 3 h and from 0.24 to 1.09 μm after 6 h of carbonitriding. The contact angle was 38° and 30° for 3 h and 6 h, respectively.
