Abstract: A bonding wire according to the invention contains a core having a surface and a coating layer which is at least partially superimposed over the surface of the core. The core contains a core main component selected from copper and silver and the coating layer contains a coating component selected from palladium, platinum, gold, rhodium, ruthenium, osmium and iridium. The coating layer is applied on the surface of the core by depositing a film of a liquid containing a coating component precursor onto a wire core precursor and heating the deposited film to decompose the coating component precursor into a metallic phase.

Abstract: The cook top includes a colorless transparent glass ceramic plate, which is provided with an opaque coating extending over its underside, except that in at least one window area a window coating is provided on the underside of the glass ceramic plate area instead of the opaque coating. In order to optimize colored displays arranged under the at least one window area and to facilitate the use of capacitive touch sensors, the window coating is a burned-in noble metal preparation with an electrical surface resistance of 1 M?/? and in the at least one window area the glass ceramic plate coated with the window coating has a transmission in a range from 1.0 to 21.0% and a light scattering in a range of from 0.0 to 1.0% for visible light with wavelengths of from 400 nm to 750 nm.

Abstract: The glass ceramic plate for a cooking apparatus is transparent to visible light and IR radiation and has a noble metal film on its underside. The noble metal film is composed of an alloy of gold, platinum and/or palladium, which imparts a reflective property to it. It contains from 0 to 5 percent by weight, in relation to a total metal content, of silver, copper, silicon, bismuth and other metals that are not noble metals. The glass ceramic plate coated with the noble metal film has a spectral transmission of 0 to 12% in the infrared region of the spectrum. When a decoration consisting of a grid of unsymmetrically distributed elements is provided on the topside of the glass ceramic plate, defects in the glass ceramic material can be concealed. The invention also includes a method of coating.
