In this work, the technique of Direct Laser Interference Patterning (DLIP) was used to fabricate micrometric structures at surface Cobalt-Chromium-Molybdenum and AZ91D magnesium alloys. Line-like patterns with spatial periods 5 μm were textured using an ultra-short pulsed laser (10 ps pulse duration 1064 nm wavelength) a two-beam interference setup. The topography, morphology, chemical modifica...

Herein, a NiCrAl coating was prepared on the AZ91D magnesium alloy by cold spraying technology. The microstructure, wear resistance, and corrosion resistance of sprayed were studied compared with two coatings plasma spraying. results showed that porosity two-plasma 3.21% 2.66%, respectively, while only 0.68%. hardness (650 HV0.1) higher than those (300 HV0.1, 400 HV0.1). In abrasion test, lower...

In the present research work, friction stir processing (FSP) has been adopted for fabri­cation of nano-hydroxyapatite (nHAP) reinforced AZ91-D Mg-alloy matrix surface com­posite (NMMSC). The NMMSC was developed to replace conventional bio-implants materials short-term usage. prepared by adding nHAp rein­forcement in 12.5 % volumetric proportion alloy using grooving technique followed FSP. FSP p...
