Abstract:
An ion beam deposition method is provided for manufacturing a coated substrate with improved abrasion resistance, and improved lifetime. According to the method, the substrate is first chemically cleaned to remove contaminants. In the second step, the substrate is inserted into a vacuum chamber, and the air in said chamber is evacuated. In the third step, the substrate surface is bombarded with energetic ions to assist in the removal of residual hydrocarbons and surface oxides, and to activate the surface. Alter After the substrate surface has been sputter-etched, a protective, abrasion-resistant coating is deposited by ion beam deposition. The ion beam-deposited coating may contain one or more layers. Once the chosen thickness of the coating has been achieved, the deposition process on the substrates is terminated, the vacuum chamber pressure is increased to atmospheric pressure, and the coated substrate products having improved abrasion-resistance are removed from the vacuum chamber. The coated products of this invention have utility as plastic sunglass lenses, ophthalmic lenses, bar codes scanner windows, and industrial wear parts that must be protected from scratches and abrasion.

Abstract:
A process for stabilizing strip in a plant for coating strip material, in which a metal strip is taken through a container holding molten coating material that has, below the melt surface, a through channel, in which induction currents are induced by an electromagnetic travelling field in the coating material and, in interaction with the electromagnetic travelling field, generate an electromagnetic force to retain the coating material. In the region of the through channel, a controllable magnetic field superimposed on the modulation of the electromagnetic travelling field is applied, whose field strength and/or frequency are adjustable as a function of sensor-detected position of the strip in the coating channel.

An apparatus and method for spraying an atomized liquid compound onto a sheet material traveling along a material coating process line. The apparatus and method heats and mixes a liquid compound then atomizes and sprays the atomized liquid compound to coat the sheet material. The apparatus and method selectively provide an atomized liquid compound which improves coating, dries quickly on the sheet material, and increases process line productivity.
Abstract:
A method of determining direction-dependent properties of coatings, in which measurements of coating properties are made along a test track (4a, 4b) on a sample coating using one or more measuring instruments and at least one measurement is recorded in relation to direction (6). The course of the sample coating is such that there are points of identical coat thickness (2) with different coat-thickness gradients (5) along the test track.
