  • Process for reducing particle defects in arc vapor deposition coatings
    Patent number: 5738768
    Abstract: A process for reducing particle defects in an arc vapor deposition coating on a substrate comprises the steps of providing a metallic wire mesh, providing an arc source adapted to impart a positive charge on coating macroparticles produced during arc vapor deposition, positioning the wire mesh in between the arc source and the substrate, applying a negative bias voltage to the wire mesh and entrapping positively charged macroparticles on the negatively charged wire mesh during coating deposition.
