Title: John L Chesterfield: Innovator in Anodic Coatings
Introduction
John L Chesterfield is a notable inventor based in Indianapolis, IN (US). He has made significant contributions to the field of anodic coatings, particularly for applications in space environments. With a total of 2 patents, Chesterfield's work focuses on enhancing the performance of materials used in extreme conditions.
Latest Patents
Chesterfield's latest patents include a high-absorptance high-emittance anodic coating. This innovative coating is designed for use on aluminum substrates, where maintaining a high solar absorptance and a high infrared emittance is crucial, especially in low earth orbit space environments. The anodic coating is preferably dark-colored, with black being the most effective option. It ensures that the touch temperature remains within an acceptable design range, preventing burns to astronauts upon contact. The coating achieves a unity ratio of solar absorptance to infrared emittance, which is vital for its intended applications. The invention consists of a first layer that is an acid anodized colored anodic layer for high solar absorptance, and a second layer that is a clear acid anodized layer for high emittance. The entire coating is thin, measuring approximately 1-2 mils, and is stable in the hostile conditions of low earth orbit.
