Introduction
Metals and alloys used for implants are exposed to synergistic influence of corrosive environment of human organism and mechanical factors.
The aim of this study was to determine the influence of the modified artificial plasma solutions on corrosion resistance of Ti6Al4V ELI alloy subjected to anodic oxidation and steam sterilization.
The use of these compounds allows for more accurate analysis of biomaterials degradation process.
For the R-SBF solution, the presence of calcium phosphate compounds positively influence long-term results.

Amorphous Fe-based alloys are known as soft magnetic materials of low loss, high saturation magnetization, high permeability and low coercivity.
After annealing, the alloys cooled in the air.
Magnetic hysteresis loop of alloys using VSM before and after annealing (two-step and one-step) are show in Fig. 2.

The present study aims to investigate the combined effects of cross rolling and 0.7% Ca additions during hot deformation on the microstructure and thermal properties of AZ31 magnesium wrought alloys.
This may be due to formation of different intermetallic compounds with different thermal stability and reactivity, leading to a higher exothermic reaction during heating.
Moreover, the addition of Ca to the AZ31 alloy also affect the morphology and distribution of the intermetallic compounds in the alloy, which might result the amount of the heat absorbed during the thermal processes.

For the production of additive methods used a range of materials, the main of them is
pure titanium, Ti-6Al-4V alloy Co-Cr , Al alloys , heat resisting alloys and etc.
Powder-based alloy Co-Cr, is one of the most common, being present in the range of almost all manufacturers of powder compounds for additive machines is quite expensive, the price on the Russian market comes to 350 euros per kg.
