Problems solved by technology

However, conventional ion plating technology has a high energy flow density of charged particles, and the surface temperature of the workpiece rises rapidly during coating, which causes the surface of non-temperature-resistant plastics to soften and deform, and releases impurity gases, making it impossible to coat the surface of non-temperature-resistant plastics.

Abstract

The invention belongs to the technical field of surface science and engineering, and particularly discloses a plastic surface low-temperature vacuum ion plating coating method which comprises the following steps: (1) carrying out ion beam sputtering cleaning and activation on the surface of a plastic workpiece by adopting a Hall ion source; (2) carrying out low-temperature vacuum ion plating on the surface of the plastic workpiece by adopting a vacuum magnetic filtering cathode arc source; and (3) later machining is conducted on the workpiece. The vacuum magnetic filtering cathode arc source is adopted to lead out high-purity ion flow with high energy and low flow density, deposition of the metal coating at the ultralow temperature of 75 DEG C or below on the surface of the plastic which is not resistant to temperature is achieved in the full-vacuum environment through a pure physical method, temperature rise of the plastic surface is effectively controlled, softening and deformation of a workpiece are prevented, and release of impurity gas is restrained; ablation damage of high-temperature large molten drops to a plastic workpiece is avoided, and the metal film prepared on the plastic surface is excellent in binding force and coverage rate.
