Abstract: Numerous applications for hollow glass bodies made from low melting glass material require an increase in the chemical resistance of the interior surface of the glass body. In order to avoid a disadvantageous de-alkalizing process the hollow glass body must be provided with an interior coating in a comparatively expensive prior art process. In an improved process according to the invention a glass tube acting as a semifinished product from which the hollow glass body is made is provided with an interior coating of oxide material, preferably SiO2, Al2O3, TiO2 or mixtures thereof, having a predetermined coating thickness according to the required chemical resistance or working conditions for forming the glass body and then the hollow glass body is made from the glass tube. The coating is advantageously provided by means of a PICVD process.

Abstract: A PCVD process for producing coating layers of uniform thickness of domed substrates. The substrate surface to be coated is arranged in relation to the gas passage surface of a gas showerhead. In order to determine the appropriate processing parameters, in a first series of tests for one type of substrate to be coated, the size of the gas passage surfaces and the gas mass flows through the gas passage surfaces are kept constant, while the intervals between plasma impulses are gradually modified, from an initial value t.sub.A until an optimum value t.sub.eff is determined, and until the uniformity of the thickness profile of the layers generated on the substrate may no longer be improved. If required, during a second series of tests, the value t.sub.eff may be kept constant, while the thickness profile of the layers is further modified by further optimizing the local parameters and/or the gas mass flows until layer uniformity may no longer be improved.

Abstract: A process and a device for coating the inner surface of a greatly arched, essentially dome-shaped substrate by CVD are described. In the process, the reaction gases, which contain the layer-former molecules, are conveyed into the reaction chamber containing the substrate(s) to be coated, through at least one gas inlet, placed facing the vertex of the dome at a distance from the surface to be coated. Deposition of the layer material on the substrate is brought about in a way known in the art by producing a reaction zone on the inner surface of the substrate to be coated. According to the invention, the reaction gases do not, as is usual for known processes, flow slowly into the reaction chamber. Instead, for production of a uniform coating, the reaction gases are introduced into the reaction chamber at a high speed such that the product of Reynolds number, R, of the gas jet in or in the immediate vicinity of the gas inlet and the distance, h, between the gas inlet and the dome vertex is:400<R.times.
