How does laser metal deposition work
WebAug 6, 2002 · Physical vapour deposition (PVD) is fundamentally a vaporisation coating technique, involving transfer of material on an atomic level. It is an alternative process to electroplating. The process is similar to chemical vapour deposition (CVD) except that the raw materials/precursors, i.e. the material that is going to be deposited starts out in ... Web2 days ago · The LMD process begins when a high-wattage fiber laser focuses on the workpiece, heating the point into a so-called melt pool. The nozzle (s) then deposit a spray …
