“…The laser modification in a nitrogen environment for low power and number of pulses presented in work [60] showed a higher roughness than for the same modification in the presence of air, while in the case of a modification in the presence of argon the modified surfaces-for different laser powers of 5 mJ and 15 mJ and the number of pulses of 50 and 150-were characterized by the highest roughness among all the modified surfaces. The conclusions in [60] are confirmed in [65], where the reason for the lower surface roughness after modification in a nitrogen environment was due to the formation of titanium and nitrogen compounds and the formation of a smaller heat-affected zone. The authors of that article also indicated that for a smaller number of pulses performed, the surface roughness was lower.…”

“…Studies [8,60,65] also indicate that the operating environment of the Nd: YAG laser affects the surface roughness and morphologies. The results of EDS [8] have shown that the presence of argon affects the reduction of oxygen molecules for both commercially pure titanium and Ti13Nb13Zr titanium alloy samples; however, the modification carried out in the presence of air caused a strong passivation of the coating and, thus, increased the amount of oxygen on the surface, while the surface roughness for the modified surfaces in the presence of air was lower.…”

Laser surface modification is a widely available and simple technique that can be applied to different types of materials. It has been shown that by using a laser heat source, reproducible surfaces can be obtained, which is particularly important when developing materials for medical applications. The laser modification of titanium and its alloys is advantageous due to the possibility of controlling selected parameters and properties of the material, which offers the prospect of obtaining a material with the characteristics required for biomedical applications. This paper analyzes the effect of laser modification without material growth on titanium and its alloys. It addresses issues related to the surface roughness parameters, wettability, and corrosion resistance, and discusses how laser modification changes the hardness and wear resistance of materials. A thorough review of the literature on the subject provides a basis for the scientific community to develop further experiments based on the already investigated relationships between the effects of the laser beam and the surface at the macro, micro, and nano level.

“…In practice, heating is commonly used by flame or electrical induction. Recently, they have been focusing on themselves for changes induced by laser irradiation or electron beam techniques [2][3][4][5][6].

The diffusion aluminide coatings are used for high-temperature applications. Structural materials of particular components degrade during service due to fatigue, creep, oxidation, corrosion and erosion. The requirements of higher efficiency of modern industrial applications increase the development of new structural materials, technologies and protective coatings. Properties of many structural materials such ultimate tensile strength, creep strength and fatigue are generally optimized for maximum high-carrying loading with less emphasis on environmental resistance. For these applications, the performance characteristics are limited by the operating conditions, which can be tolerated by the used materials. The main structural materials for high mechanical and thermal loading are superalloys protected against aggressive environment by coatings. Cyclic oxidation is the superposition of thermal cycles in an oxidation environment. The main goal of the experimental work was to compare the cyclic oxidation of protective Al and AlSi coatings deposited on both Inconel 713 LC and MAR-M247 superalloys. The resulting graph revealed that samples from IN 713 LC without coating show good resistance and their mass change is maintained above zero limit. Samples from MAR 247 LC with both Al and AlSi coatings appear to be the most acceptable selection of combination relating to superalloys/coating.

“…Laser irradiation fluence tunes the kinetic energy of species in the plasma plume, influencing surface mobility that impacts nucleation events and deposit growth. Applying a precise amount of laser energy to a restricted area can result in a desired physical modification or chemical reaction, which can be carefully controlled by laser parameters [21,24,25]. When exposed to laser irradiation, a titanium surface rapidly heats up, forming a hightemperature plasma that causes instantaneous chemical reactions.…”

This study proposes a simple and controlled method for producing TiO2 with phase junction, oxygen vacancies, and Ti3+ by combining picosecond pulsed laser irradiation and electrochemical anodization. Ti mesh was pretreated by irradiating with a picosecond pulsed laser technique using an Nd:YAG laser (1064 nm) at two fluencies, 15 J/cm2 and 30 J/cm2. The samples were then subjected to electrochemical anodization to form TiO2 nanotube arrays on the previously laser-treated surface. This study will investigate the possibility of forming TiO2 nanotube arrays on a pre-laser-treated Ti substrate and determine their physicochemical and photocatalytic properties. The samples were characterized by FESEM, XRD, Raman, XPS, and UV-Vis DRS. UV-Vis spectroscopy was used to observe the progress of photocatalytic degradation for all samples, and degradation products were determined using GC-MS. With the synergistic effects of phase junction, oxygen vacancies, and Ti3+, the laser-treated TiO2 with 30 J/cm2 showed a higher photocatalytic degradation rate (85.1%) of the pesticide carbofuran compared to non-laser-treated TiO2 (54.8%), remaining stable during successive degradation cycles, which has promising practical applications.
