6. FIG. 409 Muscles connecting the upper extremity to the vertebral column. (See enlarged image). The clavicular insertion of this muscle varies in extent; it sometimes reaches as far as the middle of the clavicle, and occasionally may blend with the posterior edge of the Sternocleidomastoideus, or overlap it.
In typical commercial aluminium anodizing processes, the aluminium oxide is grown down into the surface and out from the surface by equal amounts. So anodizing will increase the part dimensions on each surface by half the oxide thickness.
The anodizing current varies with the area of aluminium being anodized and typically ranges from 30 to 300 A/m 2 (2.8 to 28 A/ft 2). Aluminium anodizing is usually performed in an acid solution, which slowly dissolves the aluminium oxide.
