WIPO Patent Application WO/2019/045520
Kind Code:
A1
Abstract:
The present invention provides a manufacturing method for a piston ring, the method comprising the steps of: placing a piston ring inside a physical deposition apparatus, introducing inert gas thereinto, and feeding reactive gas containing nitrogen gas (N2) or nitrogen atoms (N), thereby forming a nanocomposite coating film containing nitrogen on a surface of the piston ring through physical deposition of a Zr-Cu-Si based alloy target, wherein the composition of the alloy target is composed of 82-90 at% of Zr, 4-14 at% of Cu, and 4-8 at% of Si.
