Improved Process Capabilities for Groove Repair
Advanced selective plating techniques have been developed for the challenging application of repairing internal grooves that have experienced severe corrosion. Many groove configurations require uniform, high-thickness deposition of a plated deposit onto any, or all, of the surfaces with a minimal need for intermediate machining steps. This paper demonstrates how a combination of an engineered, wrap-less anode design along with optimized computer controlled operating parameters has led to reduced downtime, high quality and repeatable selective plating repairs.

Laser-Induced Selective Deposition on Metal Using Electroless Gold
Originally published as H.R. Khan, M.U. Kittel and Ch. J. Raub, Plating and Surface Finishing, 75 (8), 58-64 (1988), this paper was awarded the 1989 AESF Gold Medal. The idea was to see if shining a laser on the substrate during electroless gold plating had any significant effect. The results are presented here.

Electrocodeposition of MCrAlY Coatings for Advanced Gas Turbine Applications - 7th Quarterly Research Report
This NASF-AESF Foundation research project report covers the seventh quarter of project work (July-September 2019) on the AESF Foundation Research project at the Tennessee Technological University. The objective of the work is to study and optimize the MCrAlY electro-codeposition process to improve the coating oxidation/corrosion performance. In this quarter, the effect of the particle size of gas-atomized CrAlY powders on electro-codeposited Ni-CrAlY composite coatings was studied.
