▎ 摘  要

NOVELTY - Compressor lubricating slide comprises a slide body, a nitriding layer, a nickel-phosphorus layer, and nano-grease microcapsules. The nitriding layer penetrates into the inside and surface of the slide body, and the nickel-P layer is deposited on the surface of the nitriding layer. The nano-grease microcapsules are distributed between the slide body, nitriding layer and nickel-phosphorus layer, and the inside of the nano-grease microcapsules is filled with nano-scale solid grease; the slide body is D-type cast iron, and the pearlite content in the cast iron is less than 15%, The distribution of ferrite is network-type dendrites, and the graphite is distributed in dots. The D-type cast iron has a hardness more than 60 HRC and a strength more than 650 MPa after quenching and low-temperature tempering. USE - Lubricating sliding sheet for a compressor i.e. rotary machine type compressor. Can also be used for a centrifugal compressor. ADVANTAGE - The nickel-palladium plating layer and the sliding sheet main body have high bonding strength, excellent anti-wear property, low manufacturing cost, and small sliding sheet impact noise. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a compressor comprising a lubricating slide sheet.
