Title: Philip Warrington: Innovator in Coating Technologies

Introduction

Philip Warrington is a notable inventor based in Harwell, GB. He has made significant contributions to the field of coating technologies, particularly through his innovative patent related to sputter ion plating.

Latest Patents

Warrington holds a patent for "Coating improvements." This invention involves a process where a coating is formed on a substrate by sputter ion plating. A DC glow discharge is generated under soft vacuum conditions in the presence of the substrate and a cathode made of the coating material. This process releases material at the cathode through ion bombardment, allowing the released material to diffuse to the substrate and form the coating. To control the coating, especially when it is an alloy containing aluminum and the substrate has sharp edges, a potential is applied to the substrate in the form of an AC bias ranging from 20 to 200 volts. This method enables ion polishing during the negative part of the cycle and retention of coating material during the positive part.
