Metal reinforced refractory ceramic coating systems have been developed to successfully withstand temperatures in excess of 4000F while providing insulative values for the supporting substructure. Eighty coating compositions were formulated and thermally evaluated in the plus 4000F range. Refractory coating of model nose cones and leading edges has been accomplished by utilizing a vibratory casting technique and the feasibility of this approach has been demonstrated. Twelve small scale leading edge models and six small scale nose cone models were coated in addition to one 500 square inch leading edge and one 500 square inch nose cone model. Thicknesses ranged from 0.3 to 0.75 inch. Mechanical data and thermophysical properties of an advanced coating system were obtained. An up-to-date bibliography of reinforced refractory ceramic systems and allied subjects is included. Author
