“…Shot peening, a widely utilized mechanical cold working technique in industries like automobile manufacturing and aerospace [1,2] significantly enhances the fatigue strength, fracture resistance, corrosion resistance, and wear resistance of materials [3][4][5][6]. During the shot peening process, high-speed projectiles or particles are blasted onto the surface of the workpiece, inducing a degree of elastic-plastic deformation that creates a strengthened layer.…”

Shot peening is a widely utilized surface modification technique, and the surface morphology of the treated materials plays a crucial role in determining their friction and fatigue properties. Surface morphology generation is a pivotal process in simulating shot-peened surface friction and other performance characteristics. However, there are limited available methods for shot-peened surfaces until now. In this paper, we present a method that directly specifies the height probability distribution and power spectrum to generate shot-peened surfaces. Compared to methods that specify height parameters, this method has more flexibility. This approach replaces the traditional Johnson transformation method with an optimization algorithm to generate height data that follows a high probability distribution, while the power spectrum is derived from the Fourier transform of an exponential autocorrelation function. The results show that this approach can generate shot-peened surfaces using any conventional height parameters, with a maximum difference in height parameters between the reconstructed surface and the original surface of no more than 18.63%. Compared to the Johnson transformation method, this method significantly reduces the errors in skewness and kurtosis of the generated surface. It offers rapid surface generation for shot-peened surfaces, leading to significant time and cost savings in experiments.

“…Surface modification is a method to enhance the chemical, mechanical, and biomedical properties of titanium composition. It can be achieved by chemical or mechanical methods (11,12), such as shot penning (13,14), sol gel (15), chemical vapor deposition (16), plasmaassisted chemical vapor deposition (17), thermal sputtering (18), electrochemical plating (19, 20), and physical vapor deposition (21-23). Among the abovementioned techniques, cathodic arc evaporation, due to the creation of uniform properties such as continuous, dense, and homogeneous coating, high adhesion to the substrate, material structure protection, and the possibility of multilayer coating deposition, can be used to form nitride coatings.…”

In recent years, implants are used as prostheses to replace and protect bone. Titanium, as an implantable material, needs to improve corrosion and wear properties for better performance. Therefore, in the current study nitride coatings were applied with the aim of improving corrosion and wear properties. Cathodic arc evaporation physical vapor deposition (CAE-PVD) technique was used to deposit nanolayered CrN/CrAlN coatings on commercially pure titanium and Ti6Al4V substrates for biomaterial applications. X-ray diffraction (XRD) was used to characterize the crystal structure of the coating, and scanning electron microscopy (SEM) and field emission scanning electron microscopy (FESEM) were utilized to observe the surface morphology and cross-section of the coating. The coating adhesion was measured according to VDI 3198 standard using a Rockwell-C indenter. The corrosion behavior was evaluated by potentiodynamic polarization and spectroscope electrochemical impedance in Ringer's solution. The results showed that the nanolayered coating changed the corrosion potential from -0.368 V to -0.054 V for the titanium sample and from -0.405 V to -0.028 V for the Ti6Al4V specimen. Additionally, the corrosion current density was reduced to about eighth -one and a third for the titanium and Ti6Al4V coated samples, respectively. The capacitator circle diameters increased due to the deposition of CrN/CrAlN coating, demonstrating enhanced corrosion behavior of the coated samples compared to uncoated specimens, as the coating acted as a barrier against corrosive liquids accessing the substrate.

“…In kinematic joints (e.g., cylinder-compression rings, flap track-rollers), high-contact pressure limits the application of conventional anti-wear coatings [4]. One possible exception is fan blades, where thick, hard facing coatings protect the blades' root section and mid-span shrouds [5].…”

This study discusses the effect of a duplex aging + nitriding process on the wear resistance of an aged double-phase titanium alloy, BT22. Nitriding was applied simultaneously with the heat treatment of the alloy, which is advantageous over the conventional heat and surface treatment methods applied to titanium alloys. According to the results, the thickness of the case depth of the nitrided samples was 40–50 μm. Moreover, nitrogen was uniformly dispersed in the substrate, which was indicated by the hardness tests. The average microhardness of the substrate material was 300 HV0.01, while the hardness of the top layer was 1190 HV0.01, which is an almost four-fold increase. The applied duplex treatment substantially affected the wear performance of the tested alloy. For the untreated alloy, the maximum coefficient of friction was 0.8, while in the surface-modified sample, the maximum fluctuations reached 0.6. The abrasive wear process was dominant in the nitrided samples, while delamination and adhesive wear were observed for the untreated specimens. The nitrided alloy exhibited double the wear resistance of the untreated samples. The proposed treatment does not require additional time or energy consumption, providing a substantial technological advantage over conventional methods. Though the alpha case reduces the mechanical performance of titanium, the nitriding of only the component sections intended to withstand friction will have a positive effect.
