Investigation of Wettability Properties of Laser Surface Modified Rare Earth Mg Alloy

摘要: Abstract Mg and its alloys are used in various application areas, where the wetting property is a special requirement. For example, surface wettability of biomaterial plays vital role cell adhesion proliferation. In this context, rare earth alloy (WE54), potential biomaterial, was studied to examine behavior. order tailor properties, laser melting (LSM), single process method, adopted. paper, effective change on properties WE54 after LSM under deionized water simulated body fluid. A 500 watt nanosecond pulse Nd:YAG having wavelength 1064 nm modify properties. Microstructure morphology were examined by scanning electron microscope profilometer, respectively. Cellular structure some buds observed melted WE54. Evaporation enrichment Y up 12.10% 13.43% observed. The contact angle reduced from 81 o 41.03 treatment, whereas SBF solution it 23.13 . It indicates that also has bio-wettability characteristic, which very important for bio-applications.
