PURPOSE:To manufacture the captioned compressor with ease, and assure excellent wear resistance as well as tolerable structure of the compressor of an increase of capability of the compressor due to high speed rotation by sintering sliding parts by compounding ceramics into sintering powder. CONSTITUTION:Sliding parts such as a blade 10 and bearing blocks 6, 7 are sintered and formed. This employs a sintering powder material of iron or phosphor bronze into which ceramics excellent in wear resistance is compounded. A compounding ratio of the ceramics described above is adapted to range from about 1% or more where effect of wear resistance is manifested to about 50% where a property of finishing is not deteriorated. With use of the sintering powder including the ceramics so compounded, sliding parts are sintered.
