Title: Richard Tooth: Innovator in Trivalent Chromium Technologies

Introduction

Richard Tooth is a notable inventor based in the West Midlands, GB. He has made significant contributions to the field of trivalent chromium technologies, holding a total of four patents. His work focuses on methods that enhance the properties and applications of chromium deposits.

Latest Patents

Among his latest patents is a method for the passivation of micro-discontinuous chromium deposited from a trivalent electrolyte. This innovative method involves treating a substrate that has a layer deposited from a trivalent chromium electrolyte. The process includes providing an anode and using the chromium(III) plated substrate as a cathode in an electrolyte that contains a trivalent chromium salt and a complexant. An electrical current is then passed between the anode and cathode to effectively passivate the chromium(III) plated substrate. Additionally, the substrate may be initially plated with a nickel layer, allowing the chromium(III) layer to be deposited over it.

Another significant patent by Richard Tooth addresses the color control of trivalent chromium deposits. This method outlines steps for measuring the color of a trivalent chromium deposit standard and adjusting the color of the deposits by adding color-enhancing additives to the electrolyte. The process includes measuring the color of the enhanced deposit and making necessary adjustments to achieve the desired optical variation from the standard.
