Conclusion

Laser additive manufacturing was used to synthesize AlCoCrFeNiCu and AlTiCrFeCoNi coatings on a steel base plate and the effect of laser parameters on both compositions were studied. The laser power was varied between 600-1600 W with the laser scan speed varied from 4-12 mm/s while the powder feed rate and the gas flow rates were kept constant at 2 rpm and 3 I/min respectively. The study deduced that:
