CARRIER WITH VERTICAL GRID FOR SUPPORTING SUBSTRATES IN COATER

Various embodiments herein relate to carriers for supporting one or more substrate as the substrates are passed through a processing apparatus. In many cases, the substrates are oriented in a vertical manner. The carrier may include a frame and vertical support bars that secure the glass to the frame. The carrier may lack horizontal support bars. The carrier may allow for thermal expansion and contraction of the substrates, without any need to provide precise gaps between adjacent pairs of substrates. The carriers described herein substantially reduce the risk of breaking the processing apparatus and substrates, thereby achieving a more efficient process. Certain embodiments herein relate to methods of loading substrates onto a carrier.

METHOD OF ION-PLASMA APPLICATION OF CORROSION-RESISTANT FILM COATINGS ON ARTICLES MADE FROM ZIRCONIUM ALLOYS

A method of ion-plasma application of corrosion-resistant film coatings on articles made from zirconium alloys includes placing articles in a planetary carousel mechanism, heating the articles, and ion-beam etching and surface activation of the articles using water-cooled unbalanced magnetrons. In addition, the surface of the articles is activated using an ion source which generates gas ions with an accelerating voltage of up to 5000 V and with feeding of a bias voltage to the articles. The coating is applied by using unbalanced and balanced magnetrons simultaneously with a residual induction of the magnetic field from 0.03 T to 0.1 T. The coating is applied to articles which are made from zirconium alloys and are placed vertically in a planetary carousel mechanism. The articles are heated in the coating application process to a temperature of 150-600° C., wherein the heaters are accommodated along the entire length of the articles. This produces corrosion-resistant film coatings of uniform thickness along the outer surface of articles made from zirconium alloys and raises productivity due to an increase in the discharge power density of magnetrons.
