Composite plastic member and method for producing the same

摘要

A composite plastic member includes a first stacked body comprised of a plurality of chromium layers stacked on a plastic substrate; and a second stacked body comprised of a plurality of chromium nitride layers stacked on the first stacked body. Each of the first and second stacked bodies is formed such that a lower-hardness layer having a lower hardness than upper and lower layers which contact with and sandwich the lower-hardness layer therebetween and a higher-hardness layer having a higher hardness than upper and lower layers which contact with and sandwich the higher-hardness layer therebetween are alternately stacked in a stacking direction; and a thickness of a higher-hardness chromium nitride layer is not more than 40% of a thickness of a lower-hardness chromium nitride layer in the second stacked body. The composite plastic member has high wear resistance and satisfactory sliding performance, and the conductivity and excellent outer appearance.

1. A method for producing a composite plastic member, the method comprising:
a step of forming a first stacked body on a plastic substrate, the first stacked body having multiple chromium layers, the multiple chromium layers being alternately formed by FCVA and by sputtering; and a step of forming a second stacked body on the first stacked body, the second stacked body having multiple chromium nitride layers, the multiple chromium nitride layers being alternately formed by the FCVA and by the sputtering, wherein an uppermost layer of the composite plastic member is one of the multiple chromium nitride layers formed by the FCVA.
