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.
Corrosion between anodized aluminum and steel. Aluminum is a reactive metal (un-noble), which should have a low corrosion resistance according to thermodynamics. The high corrosion resistance found on aluminum nevertheless, is due to the presence of a thin, compact film of adherent aluminum oxide on the surface.he galvanic series for metals shows that aluminum will be the anode of the galvanic cell in contact with almost all other metals and hence the one which suffer from galvanic corrosion. The galvanic corrosion performance of the different aluminum alloys is quite similar, so that changing alloys cannot solve the problem.
