“…Ming et al [4] have reported, for laser cladding of Ni based powders on an AISI 1020 substrate (steel), that the dilution increases with the increase of the scanning speed and the decrease of the powder feeding rate (PFR). Moosa et al [5] found the same trend during laser cladding of Ni-10 wt%Al and Ni-30 wt% Al on Inconel 617 substrate. In fact, they showed that dilution depends both on laser scanning speed and on chemical composition of involved materials.…”

et al.. Laser cladding of Ni based powder on a Cu-Ni-Al glassmold: Influence of the process parameters on bonding quality and coating geometry. a b s t r a c tLaser cladding of a Ni based powder on cupro-nickel-aluminum (Cu-Ni-Al) substrate was performed with a 4 kW continuous laser. The Cu-Ni-Al alloy is used for its thermal properties in glass mold industry. The role of the Ni based alloy clad is to protect the mold without affecting its thermal properties by limiting the heat-affected zone. The objective of this research is to produce a well bonded Ni based melted powder without pores or cracks and with a very small dilution zone on a non-planar surface (curved section). The impact of the process parameters such as laser power, scanning speed and powder feeding rate on the coating geometry was investigated with an experimental design technique analysis using the ANOVA (Analysis of variance) method. It was used to determine and represent the influence of each process parameter on the coating geometry (width, height) and the bonding quality. This ANOVA analysis led to a parameter combination to optimize the bonding quality between the Ni coating and the Cu-Ni-Al substrate taking into account the industrial geometrical constraints. More, an analytical calculation allowed to estimate the power necessary for bonding as a function of laser scanning speed and powder feeding rate.

Geometrical dimensions could play a potential role in the function of laser cladding of nickel-base powder on the cold-rolled carbon steel substrate. The geometrical dimensions and their impact on the efficiency of the process of laser cladding of nickel-base powder (Ni -10wt% Al) on cold rolled 0.2% carbon steel substrate was investigated. This work focused on the effect of laser-specific energy input of CO2laser. The geometrical dimensions of cladding regions are including cladding width, cladding height, depth of dilution, contact angle, dilution area, cladding area, and heat-affected zone dimensions determinations. The laser power (1.8 kW) was used at different traverse speeds (1.5, 3.6, 5, 7.1, 8.6, 12.5 mm/s) with (3mm) laser beam diameter. The feed rate was kept constant after many preliminary claddings at approximately 11 g/min. Fluence values ranged from (48-400J/mm2), and the power density value was (255W/mm2). A minimum dilution percentage (25%) was obtained at the highest fluence value (400 J/mm2). Observations were measured using an optical microscope, scanning electron microscopy, and Image software. Obtained results indicated that the increase in the fluence leads to an increase in height of cladding, HAZ region but lower depth of dilution

“…For simple's track, it is suggested to keep values between 10% and 20%. However, for LC, it is generally recommended to limit the dilution percentage to 10% [31]. It is important to consider both laser power and laser speed as key factors in controlling dilution during laser processing [32,33], Moosa, Kadhim, and Subhi [34] emphasize the importance of beam speed, whereas Kusmoko et al [35] prioritize laser power.…”

Additive manufacturing (AM) technology, characterized by layer-by-layer deposition, is emerging as an alternative to produce parts, typically with complex geometries, and has recently become an option for mass production. This technology has been adopted by several industries due to its ability to save material resources and processing time. In addition, it could lead to component weight reduction, design optimization and the development of new materials. Among the AM processes, laser metal deposition (LMD) offers a high build rate and allows for larger deposition volumes compared to powder bed-based technology, resulting in lower manufacturing costs. Several industries, such as aerospace and defense, have focused on the use of LMD due to the opportunities for cost savings, increased productivity, and repair of large mechanical components. In particular, LMD could be used in the aerospace industry for the manufacture and repair of engines, turbines and propulsion systems, space shuttles, communications satellites. Currently, several types of metals, including important engineering materials such as steel, aluminum, and titanium, can be used to produce parts with high levels of precision and excellent properties. The use of martensitic stainless steels has increased in the automotive, aerospace and defense industries, mainly due to their mechanical properties such as high flow resistance and reasonable ductility. However, the deposition of martensitic stainless steels using LMD presents challenges in the selection of parameters, morphology configurations and phase evolutions to ensure the required mechanical properties. The objective of the present work was to evaluate the deposition parameters for laser cladding using LMD with martensitic stainless steel AISI 431 powder. In addition, morphological aspects were analyzed. The microstructural evolution was assessed using optical and electron microscopy. The results show dilution values between 10 and 27% were found for power values between 1400 and 1600 W and laser beam velocities of 9, 14 and 16 mm/s. Microstructural characterization revealed martensite and ferrite phases in the depositions. Several factors influence the geometric and microstructural characteristics of the laser cladded deposits, such as the morphology and size distribution of the filler particles, the chemical composition of the materials, the flow rate and deposition method of the filler, and the power and beam speed of the laser.
