“…Applied in this manner, laser heating permits us to increase the plasticity of local sections of the material. The use of laser annealing can be extraordinarily effective for processing materials such as hard alloys, heat-resistant steels and alloys, and hardened or work-hardened alloys [69,70].…”

We considered possibilities of an application of diffractive free-form optics in laser processing of metallic materials in aerospace production. Based on the solution of the inverse problem of heat conduction, an algorithm was developed that calculates the spatial distribution of the power density of laser irradiation in order to create the required thermal effect in materials. It was found that the use of diffractive optics for the laser beam shaping made it possible to obtain specified properties of processed materials. Laser thermal hardening of parts made of chrome–nickel–molybdenum steel was performed. This allowed us to increase the wear resistance due to the creation in the surface layer of a structure that has an increased hardness. In addition, a method of laser annealing of sheet materials from aluminum–magnesium alloy and low-alloy titanium alloys was developed. Application of this method has opened opportunities for expanding the forming options of these materials and for improving the precision in the manufacturing of aircraft engine parts. It was also shown that welding by a pulsed laser beam with a redistribution of power and energy density makes it possible to increase the strength of the welded joint of a heat-resistant nickel-based superalloy. Increasing the adhesion strength of gas turbine engine parts became possible by laser treatment using diffractive free-form optics.

“…In addition, X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) techniques were used to characterize the composition of the oxide films and examine the distribution of key elements, particularly molybdenum which has been not well defined or understood in previous studies. [26,27] Furthermore, colorimetric measurements were taken to quantitatively assess the alterations in color induced by laser processing. Additionally, this research establishes for the first time a correlation between laser morphology and the resultant coloration, giving further insight into how laser surface interaction mechanisms influence both brightness and hue perception.…”

This paper presents the development of a model for Nd:YAG laser surface oxidation of 316L stainless steel. A full factorial design of experiments (DOE) are implemented to produce a model for the prediction of elemental composition and color. The elemental composition of the films produced where measured using an X‐ray photoelectron spectroscopic (XPS) and the color is measured using optical reflectance spectroscopy. Oxide layers produced have a Cr/Fe ratio in the range of 0.13–2.09, and highly controllable color variation via single‐pass laser process. The effect of the process parameters used such as power, frequency, and scan speed on laser‐induced oxides is examined with an aim to produce a model suitable for predictive control of the elemental composition and color of the oxide film. Surface morphology control via alteration of the laser power is an important factor for defining the resulting coloration. A new finding from this work is the discovery that within the range of laser surface processing parameters investigated, the molybdenum concentration is inversely proportional to the chromium concentration. This paper provides data required for control of 316L‐SS surface chemistry, and for the expansion of the current thermokinetic model to incorporate the mechanistic effect of molybdenum.

“…The problem of the biocompatibility of materials is a matter of great importance in medical materials science. To increase the biocompatibility of implants, ______________________________ additional coatings [7], [11] and surface modifications [10], [14] are applied to their surface. There has been a recent growth in interest regarding calcium-phosphate (СаР) and hydroxyapatite Ca 10 (PO 4 ) 6 (OH) 2 (HA) coatings, which significantly increase the adhesive strength of implants with bone tissue [5], [19], [22].…”

Purpose: The main goal of the work was to find the interconnection between the high-frequency magnetron sputtering parameters and the adhesion properties of CaP coatings formed on the surface of titanium substrate. Methods: Calcium-phosphate coatings, similar in composition to hydroxyapatite, were generated by high-frequency magnetron sputtering on titanium substrate at different values of high-frequency specific power over times of one and two hours. Afterwards, the generated coatings were studied using the method of X-ray phase analysis, and sclerometric tests (scratch test) were carried out. The adhesion strength of the deposited coatings was tested for different coating thicknesses from 0.45 to 1.1 × 10–3 mm. Results: According to the results of sclerometry, it was found that with an increase in the high-frequency specific power of plasma to 3.15 W/cm2, the adhesion strength of the calcium-phosphate coating also increases. For all the coatings, the critical loads at which the coating completely exfoliated from the substrate were determined. Conclusions: According to the research results, the most optimal conditions for obtaining high-adhesive calcium-phosphate coatings were determined.
