Title: Innovations of Stephen F Corbin

Introduction

Stephen F Corbin is a notable inventor based in Kitchener, Canada. He has made significant contributions to the field of engineering with a total of five patents to his name. His work primarily focuses on advanced materials and processes that enhance manufacturing techniques.

Latest Patents

One of his latest patents is a "System and method for closed-loop control of laser cladding by powder injection." This invention involves a system that monitors and controls the laser cladding process in real-time. It combines laser cladding techniques with automated direct feedback control to ensure high-quality clad characteristics. The system utilizes optical CCD-based detectors and a pattern recognition algorithm to assess the clad's dimensions, solidification rate, and roughness. These parameters are then fed into a closed-loop control system to adjust laser power and table velocity, ultimately producing the desired clad quality.

Another significant patent is for "Variable melting point solders and brazes." This invention features compositions that include a low melting point metal or metal alloy powder combined with a higher melting point metal powder. The in-situ alloying that occurs upon heating allows for solidification at the solder or braze temperature, creating a new, higher solidus temperature with minimal intermetallic formation. For instance, a solder comprising Sn powder mixed with a Sn-Bi eutectic powder has an initial melting point of 140°C and a re-melt temperature of 220°C after heating due to in-situ alloying.
