NDT is one of the many methods used to detect the presence of discontinuities (disabled) deep, surface defects, defects near the surface (sub-surface) of equipment made of metal or alloy. These defects can be cracks (crack), disability gases, penetration [...]

The examinations were used to detect surface defects on porous solids are not porous. Defects that occur may arise because the manufacturing process or because of fatigue (fatigue) on the object that has been in use long enough. Cracks in investigating [...]

Magnetic particle inspection - for basic
Posted by metal on
A way of knowing the existence of cracks or defects that exist on the surface (surface or sub surface discontinuities) in ferromagnetic materials. The working principle of this test is based on the nature of ferromagnetic objects that will give the [...]

Arrangement of atoms in solids can be expected if the inter-atomic known whether or not to have directional properties. The atoms in the belt by bonding lead (covalent bonds, permanent dipole) lined up in one particular rule to satisfy the valence angle. [...]

In the crystal complex, plays a variety of atoms and the bond is a bond mix in many ways. The crystal structure thus can be understood when considering that the crystal is composed of a combination of coordination polyhedron, in which small stuan of [...]

The number of adjacent atoms covalently bonded to specific atoms, in the limit by covalent valence of the atom. Covalent valence is usually small, most of the covalent structures of molecular crystals, in which covalent bonds are found only on the molecule [...]
