CHAMBERS FOR PROMOTING SURFACE ADHESION UNDER VACUUM AND METHODS OF USING SAME

摘要

In one aspect, the present invention provides a method of depositing a layer of surface coating material. The method is carried out in a vacuum chamber and comprises the steps of depositing a layer of surface adhesion promotion material on a surface of a substrate; and depositing a layer of a surface coating material on a surface of the layer of the surface adhesion promotion material so that the layer of surface coating material has an adhesion of greater than about 3.75 pounds per inch according to the hesiometry test. In another aspect, the present invention provides an article of manufacture. The article comprises a substrate, a layer of surface adhesion promotion material and a layer of a surface coating material. The layer of surface adhesion material is supported by the substrate, and the layer of a surface coating material is supported by the layer of surface adhesion promotion material. The surface coating material has an adhesion of greater than about 3.75 pounds per inch as measured by the hesiometry test. In a further aspect, the present invention provides a vacuum chamber. The chamber comprises a body, a reservoir and plumbing. The body has an orifice with a diameter of less than about 75 mils disposed therein. The reservoir is capable of containing a surface adhesion material. The plumbing is disposed along the perimeter of the orifice of the body to physically connect the plumbing to the body. The plumbing is also physically connected to the reservoir. The plumbing has an orifice disposed therein such that the reservoir is in fluid communication with the body.
