  • Publication number: 20160138171
    Abstract: The present invention proposed manufacturing device of coating layers with good conductivity and corrosion resistance at high productivity comprising etching the oxide layer on the stainless steel substrate by plasma etching to activate the surface and prevent from decreasing it's conductivity, coating metal nitrides like CrN or TiN in nano size thickness on the etched surface and coating carbon layer at nano size thickness on top of it. According to the present invention, it is possible to produce manufacture fuel cell bipolar plate, electrode material and stainless steel with reinforced conductivity and corrosion resistance in mass.

  • Patent number: 9267201
    Abstract: The invention is upon anti-static wrapper; specifically upon a new technology to manufacture anti-static wrapper using new materials which is different from those manufacture by spreading a surfactant or metallic materials. The aim of this invention is to manufacture a new and semi-permanent anti-static wrapper with excellent electric dissipation and adhesion to polymer film by depositing DLC film on polymer film. This invention also supplies the magnetic enhancing ion gun (MEIG) depositing device and high productive Roll-to-Roll device in which DLC film can be deposited on polymer film.

  • Patent number: 6346181
    Abstract: Disclosed is an Ni-plated layer of biaxial texture, which is formed by electroplating. In the Ni-plated layer,peaks measured on a &thgr;-rocking curve have a FWHM of 7° or less in terms of the misorientation on the c-axis; and peaks measured on &phgr;-scan have a FWHM of 21° or less in terms of the misorientation on the plane formed by the a-axis and the b-axis. Also, a process of electroplating a Ni layer are disclosed. The process comprises forming a Ni-plated layer of biaxial texture under a magnetic field by electroplating and subjecting the Ni-plated layer to thermal treatment to develop the biaxial texture. This electroplating process is expected to give a significant contribution to the development of the electroplating technology and to replace the vacuum deposition used for the preparation of thin film magnetic materials or thin film piezoelectric materials.
