Title: Stephen Moray Bagnall: Patents in Alloy Testing and Coating Assessment.

Introduction

Stephen Moray Bagnall is an inventor associated with Bristol, Great Britain. His work includes methods for evaluating alloy oxidation resistance and assessing the degradation of protective coatings. He is named on 3 patents.

Latest Patents

One of Bagnall’s latest patents describes a method for testing an alloy’s resistance to oxidation. The process applies salt to the alloy’s surface, heats the alloy in an oxygen-containing atmosphere at a temperature of at least 1,000°C, and repeats the heating and cooling cycle while maintaining a specified salt level. Periodic weighing helps determine oxidation resistance. The salt accelerates testing and is intended to reproduce conditions that alloys may encounter in gas turbine engines.

Another patent presents a non-destructive method for assessing degradation in an oxide-forming coating. It measures the component’s surface roughness after operational use and uses the relationship between roughness and depletion of the coating’s oxide-forming element to estimate the extent of degradation.
