Aluminum-magnesium samples prior spraying were prepared with mechanical treatment (blasting with Al2O3). 95Ni-5Al coatings on aluminum-magnesium alloys were sprayed with different parameters of process and coating‘s thickness, porosity, microhardness and microstructure were evaluated.
It is crucial for bioabsorbable magnesium alloys to control the corrosion rate depending on the condition of affected parts. The morphology and composition of anodized films of pure magnesium was then varied with the anodizing voltage and composition of electrolytes. It was revealed that the corrosion rate of pure magnesium in a simulated body fluid noticeably decreased by the incorporation of

Magnesium based alloys gained great interest for medical biodegradable appliions. Limitations arise from high corrosion rates and mechanical properties of the Mg based alloys. In recent work it was shown that the corrosion rate of a precipitate free Mg-6Ag thin film can be reduced by a factor of three compared to pure sputtered Mg. As Mg-6Ag coines the very promising corrosion results
High cycle fatigue properties of high-pressure die-cast magnesium alloys AZ91 hp, AM60 hp, AE42 hp, AS21 hp and of similarly produced cast aluminium alloy AlSi9Cu3 have been investigated. Ultrasonic fatigue tests up to 109 cycles show mean fatigue limits of approx. 38–50 MPa (magnesium alloys) and 75 MPa (AlSi9Cu3) in the tested casting
