The report covers activities accomplished to develop an electrophoretic coating method for the application of SERMETEL W to all critical surfaces of the exhaust diffuser, air diffuser and combustion chamber housing of the T-53 engine. SERMETEL W has been classified by various engine manufacturers and DOD agencies as the best coating available for corrosion protection. During this phase the coating tanks with associated recirculation system were run for an extended period, cleaned and adjusted. The humidification chamber installation also was completed and checked for proper performance. Studies of coating dispersion characteristics were begun. Two characteristics, the effect of cathode area on current density and the effect of the age of the dispersion on current, were studied. Utilizing representative segments of the three components, dummy coating runs were made to determine coating coverage. Electrode design was modified as determined necessary to provide complete coverage. Based on successful dummy runs with the sectors, fabrication of electrodes for the full size components was initiated. The electrodes for the combustion chamber housing were completed during this period. Author
