In this study, niobium carbidestainless steel 304 (SS304) metal matrix composite was processed using laser engineering net shaping (LENS). By laser bonding NbC particles with SS304, the NbC dispersed at the grain boundaries and in the lattice. XRD results showed that NbC addition caused lattice strain, which resulted in the strengthening of the matrix metal, increase hardness, and a >75% decrease in wear rate. The carbides became abrasive particles in the metal during wear, which increased the wear resistance along with the coefficient of friction (COF). Such coating approach via LENS™ could be utilized in specific locations to protect existing steel parts or be added to new ones that may be sensitive to wear degradation as opposed to treating the entire part surface.

“…Stiffened parts and reinforced panels can be formed by laser beam irradiation [120][121][122]. The laser beam can be used in various processes like laser peen forming (LPF) [123][124][125][126][127], laser shock peening (LSP) [128,129], Laser solid forming (LSF) [130,131], laser folding [132], modification of mechanically bent parts (correction of spring back, over-bending or distortion of sheet [133]) and measuring the bending angle [134].…”

Laser forming is an emerging manufacturing process capable of producing either uncomplicated and complicated shapes by employing a concentrated heating source. The heat source movement creates local softening, and a plastic strain will be induced during the rise of temperature and the subsequent cooling. This contactless forming process may be used for the simple bending of sheets and tubes or fabrication of doubly-curved parts. Different studies have been carried out over recent years to understand the mechanism of forming and predicting the bending angle. The analysis of process parameters and search for optimized manufacturing conditions are among the most discussed topics. This review describes the main recent findings in the laser forming of single and multilayer sheets, composite and fiber-metal laminate plates, force assisted laser bending, tube bending by laser beam, the optimization technique implemented for process parameters selection and control, doubly-curved parts, and the analytical solutions in laser bending. The main focus is set to the researches published since 2015.

“…The element is heated by the energy from the laser beam acting on it. The appropriate geometry and trajectory of the laser beam leads to the desired shapes of the element [8][9][10][11][12]. MEJ with combined bellow-lens shape, are made of a metal tube with an appropriate diameter and wall thickness.…”
