Parameters Development for Optimum Deposition Rate in Laser DMD of Stainless Steel EN X3CrNiMo13-4

Abstract Laser Direct Metal Deposition (DMD) has been developed as a manufacturing process to deposit coatings on existing materials and proves advantageous in Additive Manufacturing (AM) of complex precise components. However, it is necessary carefully determine the proper parameter combinations make this method economically viable for industries. The intent study address enhancement productivity laser DMD stainless steel EN X3CrNiMo13-4. Accordingly, effects main parameters power P , scan speed v powder flow rate $$\dot{\mathrm{m}}$$ m ˙ spot diameter s track geometries build-up are discussed. regression analysis conducted derive correlations between combined set deposition rate. results show good linear correlation R 2 >0.9 geometrical characteristic aspect ratio, dilution, constructed processing map, using equations, presents selection connection with rate, dilution
