Title: Denis William Hazelden: Innovator in Coating Technologies
Introduction
Denis William Hazelden is a notable inventor based in Bishops Stortford, GB. He has made significant contributions to the field of coating technologies, holding 2 patents that showcase his innovative approach to materials science. His work primarily focuses on enhancing the performance and cost-effectiveness of electrolytic capacitors.
Latest Patents
Hazelden's latest patents include a method for coating powder with valve-metal. This process involves rotating the powder in a drum to expose it to valve-metal vapor, which is generated by evaporating a source of valve-metal. In particular, when coating with aluminum, the vapor is produced by directing aluminum wire onto a heater, while controlling the admission of oxygen or air to manage agglomerate formation. Additionally, he has developed an anode electrode for an electrolytic capacitor that utilizes tantalum-coated alumina particles. This innovation provides improved breakdown properties compared to pure tantalum particles, resulting in substantial savings in tantalum material costs. The coating features both anodized and unanodized portions, with the thickness of the unanodized portion not exceeding 0.5 microns.
