A single NEXPLANON implant is inserted subdermally in the upper arm. To reduce the risk of neural or vascular injury, the implant should be inserted at the inner side of the non-dominant upper arm about 8-10 cm (3-4 inches) above the medial epicondyle of the humerus.
Graphitic corrosion is selective leaching of iron from gray cast iron, where iron particles are removed and graphite grains remain intact. Graphitic corrosion is also known as selective leaching, dealloying, demetalification, parting and selective corrosion.
These are examples of steel machines and structures on a farm that show signs of rust (iron oxide) formation, a type of corrosion. Rusting is an example of a process called corrosion. Corrosion means that a chemical reaction has occurred in which metal atoms have combined with oxygen to form an oxide coat.
