“…The XRD after sandblasting contained (α + β) and SiO 2 , Figure 1 b. The XRD of the SB sample revealed a broadening of the peaks in comparison to the M sample, reflecting a reduction in crystallite size, corroborating earlier findings [ 5 , 49 ]. The XRD patterns of the MT and SBT Ti64 alloy reveal the existence of TiO 2 (rutile) along with α -Ti and β -Ti peaks.…”

“…Specimen SB exhibited a nearly identical behavior, characterized by a substantial fluctuation in the anodic branch. It has already been reported that the active surface with high surface roughness caused by the SB treatment normally exhibited some fluctuation in the anodic region of the PDP curve [ 5 ].…”

“…Ti6Al4V(Ti64) has been used in bio-implant applications in orthopedic and dental applications [ 1 ]. Surface characteristics of the bio-implants such as surface microstructure, coarseness, surface wettability, and energy of implants influence corrosion protection [ 5 ], and implant longevity [ 6 ]. Surface treatment can be performed on biomedical implants to alter their surface wettability and surface energy [ 7 ], and improve osseointegration [ 8 ].…”

“…Blasting is an effective method for increasing the surface roughness of metallic biomaterials and encouraging osseointegration. Blasting Ti6Al4V alloy has been identified as a low-cost method of increasing surface roughness [ 5 , 31 , 32 , 33 ]. Heat oxidation of commercially pure Ti implants appears to increase the percentage of bone-implant contact by the oxidized surface in vivo [ 34 ].…”

The biomedical Ti6Al4V alloy was thermally treated under sandblasting and mirror finish surface preparation conditions. The surface morphology, structure, roughness, wettability, and energy were characterized. Microhardness and in vitro corrosion studies were carried out. X-ray diffraction results showed a formation of rutile TiO2 phase for thermally treated samples under different pretreated conditions. The thermally oxidized samples exhibited an increase in microhardness compared to the untreated mirror finish and sandblasted samples by 22 and 33%, respectively. The wettability study revealed enhanced hydrophilicity of blasted and thermally treated samples. The surface energy of the thermal treatment samples increased by 26 and 32.6% for mirror surface and blasted preconditions, respectively. The acquired in vitro corrosion results using potentiodynamic polarization measurement and electrochemical impedance spectroscopy confirmed the surface protective performance against corrosion in Hank’s medium. The enhanced surface characteristics and corrosion protection of treated Ti6Al4V alloy give it potential for bio-implant applications.

“…When testing materials used in biomaterials, corrosion resistance is as important as surface topography. The corrosion resistance of these materials can be tested in reagents that simulate body fluids, such as a simulated bovine serum [4], artificial saliva [5], Ringer solution [6], or Tyrode solution [7]. Nitriding is one of the methods related to the production of surface layers used in surface engineering to improve the properties of the surface [8,9].…”

Evolution of the Geometric Structure of X39Cr13 Steel upon Thermochemical Treatment Specific to Medical-Grade Steels

This paper presents the results of the multi-aspect surface characterization of X39Cr13 steel samples subjected to technological processes specific to medical instrumentation, such as heat and thermochemical treatment, as well as sterilization, which are implemented in corrosion resistance measurements. The application of numerical methods of fractal analysis to averaged profiles obtained from SEM images resulted in double-log plots of structure function, from which the determination of the fractal parameters of interest was possible. The discussion was focused on the fractal dimension D, which governs relative height variations upon scaling in length, and corner frequency fc, which separates the scaling behavior of different-order structures (particles and their aggregates). The obtained results show that the heat treatment leaves behind a granular structure of steel (D2 = 2.43; fc2 = 1.97 nm), whereas corrosion tests reveal the appearance of pits (D1 = 2.17; fc1 = 0.303 nm; D2 = 2.59; fc2 = 4.76 nm). In turn, the ion nitriding improves the resistance of steel X39Cr13 to local corrosion. The fractal analysis also shows that the structure of the nitrided layer differs insignificantly from that of the untreated material, seen only as a shortening of the radius of the self-similarity area by a factor of two (fc2 = 1 nm).
