ABSTRACT:
A scroll type fluid displacement apparatus is disclosed in which the scrolls are made of aluminum or an aluminum alloy to reduce the weight of the apparatus. The scrolls are finished by end milling and then electrolytically or chemically polished to reduce the roughness of the mating surfaces. Thereafter, at least one scroll is treated with alumite to reduce wearing due to contact between the scrolls. As a result, sealing of the fluid pockets between the scrolls during extended use of the apparatus can be maintained.
