“…Initial simulations suggested that the peak temperature of free electrons should fall within the range of 1000 to 10,000 K. Additionally, upon reaching a density of free electrons of 4.5 × 10 21 cm −3 , the computed repulsive tension in Eq. ( 11) becomes sufficiently potent to cause damage to martensite phases of bronze in high temperatures [33]. Consequently, the critical density of free electrons in this particular study is determined to be 4.5 × 10 21 cm −3 .…”

Comprehending the laser ablation mechanism is fundamental in determining how diverse laser parameters affect the quality of the ablation process. A finite difference model was developed in this study to investigate the ablation depth and temperature distribution in picosecond ablation process. The investigation involved conducting single-point laser experiments on bronze material using an ultrashort pulse laser with a pulse duration of 12 ps. The experiments were carried out with varying numbers of pulses, ranging from 1 to 80 pulses. The calculated depths of ablations were compared with experimental results. The variation of the ablation mechanism on the workpiece's surface during laser radiation was also investigated. The model established the laser-material interaction mechanisms under different incident pulses. The ionization temperature and ablated material temperature during laser processing are also determined. The results show that for the number of pulses higher than 10, the laser-material interaction changes from Multi-Photon Ionization to ablation, while in lower numbers, there are no effects of thermal damages adjacent to the laser points. The relationship between variations in the ablation depth and changes in the incidence angle was also investigated. As the incidence angle increases, the removal mechanism changes from MPI to the thermal.

“…This helped to identify individual peaks when overlapping occurred. [17,38] Furthermore, dilatometer tests were conducted on a NETZSCH DIL 402C apparatus. Dilatometer tests consisted of a reheating stage up to 1200 C followed by cooling down to room temperature to detect metastable phases that had been formed at high cooling rates during LC.…”

Microstructural and Thermal Characterization of 316L + WC Composite Coatings Obtained by Laser Cladding

Herein, a metal matrix composite (MMC) composed of 316L stainless steel and 20% in volume of tungsten carbides (WC), fabricated by laser cladding (LC) is considered. LC is an additive manufacturing technique, characterized by ultrafast cooling rates and limited diffusion, thus giving rise to out-of-equilibrium microstructures. The microstructure of the MMC is found to consist of partially dissolved WC well distributed in an austenitic matrix reinforced by a network of reaction carbides. Those mixed reaction carbides are formed from a liquid enriched in W and C due to the dissolution of the original WC in contact with the molten metal during deposition. Distribution, chemical composition, crystallographic features, and stability of the different phases are characterized in details by combining electron microscopy, electron backscattered diffraction, and dilatometry. This combination of techniques allows to distinguish among M 6 C, M 23 C 6 , M 4 C, and WC 1-x carbide, belonging to the FeW -C system and all exhibiting a face-centered cubic lattice. Moreover, results of reverse thermal analyses are considered together with microstructural data to elucidate the genesis of this complex microstructure, differentiating the phases formed in the melt pool, in the vicinity of partially dissolved WC and in the heat-affected zone between two successive tracks.

“…Due to its attractive color, this alloy material has also a large extent of use in making utensils, pottery, coins, vessels, ornaments, monuments, sculptures, statues etc. [6,7]. Bell metal alloys are conventionally found in gear, bushing or bearing type applications due to its ability to endure high strengths and heavy loads [8].…”

The electrochemical corrosion property of ternary Al and quaternary Zr added Bell metal in 0.1M Sodium Chloride solution has been experimentally conducted at room temperature. Electrochemical impedance spectroscopy (EIS) method and Potentiodynamic polarization technique are used to carry out the electrochemical investigation. Microhardness test is also conducted for all three alloys and it reveals that Al addition increases the hardness of bell metal due to the formation of different intermetallic precipitates of Cu and Al. Optical Micrograph as well as Scanning Electron Micrograph have also been studied to characterize their surface condition. It is found that Zr addition refines the grain structure of the alloy and results in increase of hardness. The EIS study reveals that the corrosion resistance is seem to be augmented with the addition of ternary Al and quaternary Zr to bell metal. The potentiodynamic polarization curves disclose that both ternary Al added and quaternary Zr added alloy show better corrosion performance than the base bell metal alloy due to the formation of stable aluminium oxide film. The currentdensity (Icorr) of base bell metal showed higher value than both ternary Al added and quaternary Zr added bell metal alloys. The corrosion potential (Ecorr) and the open circuit potential (OCP) were seen to be moved to the more positive direction for the Al and Zr added alloys. Microstructure and SEM study of the alloys after corrosion revealed a formation of an oxide film on the surface of the ternary A and quaternary Zr added alloys, the probable cause of which is the presence of Al in the respective alloys.
