Abstract: Shoes for operatively connecting a swash-plate with the compression pistons of a swash-plate type compressor are made from a novel Cu-based alloy. Improved shoes are characterized by a combination of high heat conductivity and excellent wear resistance properties particularly when subjected to a lubricating condition so severe that no lubricating oil is supplied to the surface of the shoes at the initial period of the compressor operation. At least three alloying elements are selected from Mn, Si, Pb, Sn, the IVb and VIb groups of the periodic table, and added in predetermined amounts to the Cu-based alloy, so that the properties mentioned above are simultaneously obtained. The compressor according to the present invention can be reliably employed, without the occurrence of seizure over a long operational period for air-conditioning vehicles, in which the sliding condition of the shoes is drastically varied with the rotation of the engine.

Abstract: Carbon dioxide compressors having one or more coatings with wear surfaces having electroless surface coatings are provided. Alternatively, propane compressors are contemplated having wear surface coatings. The coating is electrolessly applied and may comprise nickel and wear resistant particles, such as boron nitride. The electroless surface coatings for use with compressor machines improve corrosion and wear resistance, as well as anti-friction properties for compressors processing CO2 or C3H8 containing refrigerants. In certain aspects, a scroll machine has an Oldham coupling and/or lower bearing comprising aluminum and has an electroless surface coating comprising nickel boron nitride particles disposed on one or more wear surfaces. In other aspects, a reciprocating compressor has a wear surface, such as on a connecting rod and/or piston coated with an electrolessly applied nickel and boron nitride particle layer. Methods for making the electroless surface coatings are also provided.

Abstract: In a Ni-base alloy, an area-equivalent diameter D is calculated. D is defined by D=A1/2 from an area A of a largest nitride in a field of view when an observation area S0 is observed. This process is repeated in n fields of view for measurement, where n is the number of the fields of view for measurement, so as to acquire n pieces of data on D, and the pieces are arranged in ascending order D1, D2, . . . , Dn to obtain a reduced variate yj. The obtained values are plotted on X-Y axis coordinates, where an X axis corresponds to D and a Y axis corresponds to yj. In a regression line yj=a×D+b, yj is obtained when a target cross-sectional area S is set to 100 mm2. When the obtained yj is substituted into the regression line, the estimated nitride maximum size is ≦25 μm in diameter.
