It is one of the most common materials that are used in building construction industry.
Concrete can be readily moulded into virtually any required shape compared to other materials.
This type of materials called as fly ash.

Laser shaping of sheet materials is a flexible process and is carried out without force contact on the material, it allows forming, among other things, brittle, elastic and difficult-to-deformed materials.
It does not require heavy metal-intensive equipment and tools, allows formation of rigid, elastic materials and brittle materials.

Subsequently, the relative movement causes the cold-weld junctions to be broken and eventually led to tear off of materials from both side. 3.1.3 Fatigue wear Figure 4 shows a typical contact fatigue wear debris characterized in irregular shape, intercrossing and enrichment of fatigue micro-cracks, coarse surface appearance, large in thickness, evidence of sliding scars.
In the process of relative movement of two contact bodies, corrosive media may cause chemical or electrochemical reactions that result in materials loss.
