The article is devoted to the research of the opportunity for the increasing corrosion resistance of steel. The results of the experiments of laser processing of model samples made of carbon steel with CW ytterbium fiber laser at a wavelength of 1.06 micron. It is shown that laser processing can form resistant protective film with a thickness of 2-3 microns on the steel surface, which improve anticorrosion properties of metal. One of the possible reasons for the increase in corrosion resistance of steel is the microstructuring of its surface to form a thin film of iron carbide (Fe 3 C), which is formed as a result of heating in the temperature range from 600 to 1000 °C. Besides, the exposure to laser radiation leads to reduction of surface roughness (from R a = 0.53 μm to R a = 0.48 μm). Optimal (from the point of view of the degree of resistance to corrosion) steel processing mode corresponds to the density level of laser radiation power density of 1.5 • 10 5 W cm −2 , the conducted research allows to conclude that the use of CW fiber lasers is a promising method of improving the corrosion resistance of carbon steel.

“…Corrosion is the main problem of all metal structures and buildings. The main damage it causes is not the damage to the metal itself, but the enormous cost of the products it damages [2]. According to experts, annual corrosion losses in industrialized countries range from 2% to 4% of the gross national product.…”

“…The results show that the S–S Surface has a larger R ct and smaller CPE dl in both solutions and exhibits better corrosion resistance. The reason for this is that, on the one hand, during the laser texturing process of the Co 28 Cr 6 Mo surface, the oxidation reaction of the base metal and the generation of metal oxide layers have been shown to have a barrier effect on the soaking of corrosive ions. , In addition, the superhydrophobic and slippery surface coatings on the S–S Surface reduce the adhesion of droplets on the surface, block corrosive ions from corroding the substrate, and reduce the contact area between the sample surface and the corrosive medium to reduce the corrosion effect . Moreover, the presence of slippery properties gives the surface a self-healing property and strong protection against surface pitting .…”

“…In contrast, laser texturing has been increasingly used in the preparation of superhydrophobic surfaces and corrosion-resistant fields in recent years due to its advantages, such as processing efficiency, strong controllability, and low pollution. By imitating examples of superhydrophobicity in nature, such as lotus, water strider leg, fish scale, reed leaf, and so on, a micronanocomposite structure was established on the surface using laser texturing, and a superhydrophobic surface was prepared by adsorbing organic matter to reduce surface energy. − The general methods for adsorbing organic matter can be divided into placing and using modifiers in the air, with the latter having better effectiveness and rapidity. − Further research has found that superhydrophobic surfaces have enhanced salt corrosion resistance compared to the pristine surface, improving the service life of metals in production and usage. − There are several reasons for this corrosion resistance effect. First, the surface structure is a significant factor.…”

Cobalt−chromium−molybdenum alloy is used as a material for artificial human body components such as artificial hip joint and artificial denture and is often affected by electrochemical corrosion in human body fluids and saliva, which leads to inflammatory reactions and damage to the surrounding tissues as well as loosening and failure of the body components themselves. Few studies have been conducted to prepare corrosion-resistant coatings on the surface of Co 28 Cr 6 Mo. In this study, we used laser texturing to process a bionic 3D micronanocomposite structure on the surface of Co 28 Cr 6 Mo and quickly prepared a superhydrophobic and slippery surface coating with excellent corrosion resistance using polydimethylsiloxane solution and silicone oil modification. This surface had ultralow surface adhesion and good robustness of durability and abrasion resistance, reducing bacterial colonization or tissue adhesion and solving the problem of the lack of stability of the superhydrophobic surface. Microgrid grooves and layered nanoparticles were structurally responsible for the variation in wettability. The formation mechanism and composition of the prepared coatings were further analyzed. Electrochemical corrosion experiments were conducted on the surface in simulating body fluid and saliva environments, which showed the enhanced corrosion resistance of the prepared surface in the human body. These findings can further develop the surface functional modification of Co 28 Cr 6 Mo, accelerating basic and applied research studies on artificial human components.

Metal substrates are widely used in engineering production. However, material life reduction and economic loss due to chemical and electrochemical corrosion are a major problem facing people. Electrochemical corrosion is the main corrosion mode of metals, such as seawater corrosion. It is found that the superhydrophobic surface treated by laser texturing plays an important role in the corrosion resistance of the substrate, with the laser texturing process and post-treatment affecting the corrosion resistance. The corrosion resistance is positively correlated with the superhydrophobic property of the surface. For the mechanism of corrosion resistance, this paper summarizes the effect of micro-nano structure, surface-modified coating, oxidation layer or new product layer, surface inhomogeneity, crystal structure, and slippery surface on corrosion resistance. Superhydrophobic surface and slippery surface are two common types of bioinspired, special wetting surfaces. In order to prepare better superhydrophobic and corrosion-resistant surfaces, this paper summarizes the selection and optimization of laser parameters, surface structure, processing media, and post-treatment from the point of view of mechanism and law. In addition, after summarizing the corrosion resistance mechanism, this paper introduces a series of characterization experiments that can measure the corrosion resistance, providing a reference for preparation and evaluation of the surface.
