Abstract
A compressor is disclosed, including an outer casing and a fluid guide around a cavity within the casing. An inlet is in operative fluid communication with the cavity, and an outlet is also in operative fluid communication with the cavity. A prime mover includes an actuator disposed in the cavity. The actuator includes a surface arranged to receive fluid in the cavity from the inlet, impart compression to received fluid in the cavity, and discharge compressed fluid to the outlet. A surface of the compressor includes a cladding of a second aluminum alloy over a core of a first aluminum alloy, wherein the second aluminum alloy is less noble than the first aluminum alloy and includes an alloying element selected from tin, indium, gallium, or combinations thereof.
