Lacking osseointegration and peri-implantitis induced by bacterial infiltration are the pivotal issues for long-term clinical success of implants. In order to improve bioactivity antibacterial properties implant materials, volcano-shaped microporous TiO2 coatings doped with Zinc (Zn) were fabricated via a micro-arc oxidation (MAO) method on pure titanium (Ti). The microstructure, morphology, ch...

The paper considers possibilities to increase the wear resistance, corrosion and service life for parts of machines mechanisms via their hardening renovating using electric arc coatings characterized by high density, adhesion strength, micro hardness. Also, possibility controlling properties restored surfaces owing choice related equipment with required structure characteristics in order prolon...

Steam reforming integrated with oxidation of methanol was considered with numerical simulation. The parallel micro-channels with circular cross sections were used. Because when the catalytic deposited inside the rectangular micro-channels, it fills up the edges. Hence, the approximation of a cylindrical channel is appropriate. Effect of this changing in cross section was considered and results ...
