Band structures for binding and holding of objects made from recycled metallic materials
ArticleThe aim of the present research is the investigation of the possibility and effectiveness
of using the band structures made from recycled metallic materials for binding and holding of
objects (in particular, tubular objects as pipelines or shells). The using of band elements and
structures as such is a perspective way to increase the safety and bearing capacity of the pipelines
and vessels. Nowadays during repair works the outer surfaces of the mentioned objects are
braided by the steel tapes, i.e. the objects are strengthened by the binding. The mentioned steel
bands are specially produced for binding purpose. From the other hand after stamping of smallsize
details (like the elements of supply chains for different apparatus) the metallic waste in the
shape of perforated metallic tapes are received and needs to be reused in compliance with the
good practice in effective resource using and recycling. The band structures for binding and
holding of tubular objects, produced from the perforated metallic tape by the longitudinal
profiling, multilayer and spiral winding are presented. It is proposed to apply in industry the
composite band structures made from perforated metallic materials and epoxy matrix for binding
and holding of tubular objects as pipelines or shells, which allows simplifying and speeding up
the repair works especially in the cases of the local damages

Promising Methods for Corrosion Protection of Magnesium Alloys in the Case of Mg-Al, Mg-Mn-Ce and Mg-Zn-Zr: A Recent Progress Review
High specific strength characteristics make magnesium alloys widely demanded in many
industrial applications such as aviation, astronautics, military, automotive, bio-medicine, energy, etc.
However, the high chemical reactivity of magnesium alloys significantly limits their applicability
in aggressive environments. Therefore, the development of effective technologies for corrosion
protection is an urgent task to ensure the use of magnesium-containing structures in various fields
of application. The present paper is aimed to provide a short review of recent achievements in
corrosion protection of magnesium alloys, both surface treatments and coatings, with particular
focus on Mg-Al-Mn-Ce, Mg-Al-Zn-Mn and Mg-Zn-Zr alloys, because of their wide application in
the transport industry. Recent progress was made during the last decade in the development of
protective coatings (metals, ceramics, organic/polymer, both single layers and multilayer systems)
fabricated by different deposition techniques such as anodization, physical vapour deposition, laser
processes and plasma electrolytic oxidation
