    Abstract: A swash plate type compressor that provides long lasting high lubricating performance to the sliding contact surfaces of a swash plate end shoes. The surface of the swash plate or the shoes on which the swash plate comes in sliding contact with the shoes is provided with an alloy plating layer, in which tin is the main component, as a surface treating layer. An coating layer, in which molybdenum disulfide is the main component, is formed as a solid lubricant layer on the foregoing plating layer. Preferably, the swash plate is made of aluminum or an aluminum alloy, and its surface is provided with the plating layer and the coating layer. More preferably, the coating layer contains graphite.

    Abstract: An electrochemical method of modifying the surface hardness of a non-allotropic metal member 10, comprising: (a) forming the member to near net-shape with at least one surface 12 to be hardened; (b) subjecting the surface 12 to rapid melting and resolidification by incidence of an electrical discharge between an electrode 16 and the surface 12 closely spaced thereto, the spacing containing an electrolyte with plasma forming capability, the surface 12 being hardened by crystallographic change of the globules resulting from substitutional alloying; and (c) cropping the surface grains 29 of the surface to increase load bearing capacity while retaining liquid retention capacity.
    The invention, in another aspect, is a unitary aluminium based swashplate member useful in a compressor, comprising: (a) a plate drivingly rotatable about an axis through its centre but canted to the plane of the plate; (b) integral shoulders on opposite sides of the plate, each presenting a thrust surface for receiving a plurality of rolling bearing loads, the thrust surfaces being centred about such axis and being in a plane normal to such axis; and (c) each thrust surface having (i) a hardness enhanced thermochemically by electric discharge to a depth of 100 Mm, and (ii) a surface hardness of 1.5 MmRa or less, the thrust surfaces being effective to substantially reduce the cost of swashplate fabrication and reduce load bearing failures.
