“…There has been extensive research on the processing technique developments in laser cladding and additive manufacturing, including blown powder cladding [3, 32-34], coincident wire and powder feeding [35,36], pre-placed powder cladding [37][38][39], powder feeders and nozzles [40][41][42], the influences of the main cladding parameters (laser power, energy distribution, beam diameter, scanning speed, powder feeding rate, and so on) on the clad geometry, defects (cracks and porosity), microstructure, phases and properties and hybrid laser cladding (laser plus induction, plasma, thermal spray, and so on) [43,44]. Also there have been investigations on the comparison of cladding with different lasers and other methods, cladding process monitoring and control [5,20,[45][46][47], modelling and simulation [11,[48][49][50][51][52][53][54], and practical industrial applications [55][56][57][58][59][60][61][62]. In addition, laser cladding has been extensively investigated for the repairing and manufacture of 3D components [63][64][65][66][67][68][69][70][71][72]…”

Laser cladding is a process whereby a new layer of material is deposited on a substrate by laser fusion of blown powders or pre-placed powder coatings. Multiple layers can be deposited to form shapes with complex geometry. This manufacturing process has been used for material surface property modification and for the repair and manufacture of three-dimensional components. Laser cladding has attracted extensive research over the past 30 years. Over 2000 research papers have been published in journals and international conferences. Research in laser cladding covers many scientific issues, including processing techniques, physical and chemical properties of deposited materials and clad—substrate interfaces, microstructure and phases, rapid solidification phenomena, modelling and simulation, and systems engineering and applications. This article, focusing on the rapid heating/cooling processes and material response, summarizes the state of the art on two fundamental scientific aspects: rapid solidification and the material characteristics. The article includes a review of the microstructural refinement, extended solid solution, metastable phases, amorphous structure, and directional solidification. In addition, the article discusses the progress and state of the art in laser cladding of commercial alloy powders, carbides and intermetallics, in-situ synthesized particulate reinforced metal matrix composite coatings, compositional gradient materials, and alloy development. Laser cladding is capable of producing materials with designed macro/microstructures and properties.
