Document Type and Number:
Japanese Patent JP2017053341
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration compressor excellent in reliability without deteriorating abrasion resistance, even with low viscosity of lubricant and downsizing of a slide part.SOLUTION: At least one slide member constituting a compression element comprises a base material 150 made of a ferrous material, and an oxide film 151 formed on the surface of the base material 150. The oxide film 151 contains a portion having a larger amount of silicon (Si) that the base material 150. Consequently, abnormal abrasion due to agglutination or the like can be prevented, and reliability can be improved.SELECTED DRAWING: Figure 2
