A Novel Corrosion-Resistant Internal-Coating Method Provides Improved Hardness

摘要

A novel technology has been developed for coating the internal surfaces of parts ranging from small components to production pipe.The coating is appropriate for use in many environments for corrosion,erosion,and wear reduction.The process technology that enables the coating of interior surfaces with a hard,wear-and corrosion-resistant silicon-containing diamond-like carbon(DLC-Si)layer is described.Hardness greater than 25 GPa has been achieved while maintaining a high deposition rate.
