Abstract:

High Velocity Oxy-Fuel HVOF technology is being evaluated in this program. A number of materials are being HVOF sprayed, characterized and tested. Preliminary results point to a dramatic enhancement of properties using HVOF technology vs. traditional plasma spraying. It is proposed to offer an extension of HVOF in this proposal for renewal involving a test of the concept that the fatigue life of a machine element can be extended by HVOF coating. HVOF involves the combustion of an oxygen fuel mixture to achieve high gas velocities which are used to heat and accelerate a powdered feedstock to produce a coating. The goal of this project is to evaluate the coatings produced by these HVOF systems relative to various marine-based applications. This proposal will first outline the evaluation methods that are being used and some preliminary results will be presented.
