The internal stress of these repeated expansions and contractions results in microfissures
within the stone which serve as channels for water migration and its corrosive effects," wrote A.
In conifers, impact brittleness is attributed to anatomical factors characteristic of earlywood; in fact, when wood is subjected to impact, it undergoes a local deformation at the point of contact, giving rise to microfissures
which do not propagate easily due to the differences in the nature of its anatomical elements.
Since then, various anatomic studies have been performed on temporal bones, and theories have arisen about the significance of microfissures

in the material, which often led to catastrophic failure in long-term implanted devices such as pacemaker leads.
Wear in metal surfaces relates to some extent to the movement of microfissures
around in the metal.
This coating increases the durability of these devices, protecting them from the chip-outs and microfissures
