HIGH TEMPERATURE OXIDATION RESISTANT COATINGS FOR TANTALUM BASE ALLOYS. Second Quarterly Progress Report, September 1, 1960 to November 30, 1960
Aluminide and beryllide coatings were applied to pure tantalum and Ta- 10% W sheet and evaluated. Some work was done with niobium alloys and with tantalum compounds. Methods of application included hot dipping in aluminum and tin base baths, slurry painting of aluminum alloys, and vapor-solid reactions for beryllium. Both types of coatings appear promising for 10 hours at 2500 deg to 2600 deg F and for somewhat shorter times at 2700 deg to 2800 deg F. Tin base baths gave duplex coatings which appear self healing and resistant to damage in handling. Anomalous aluminide coating behavior was noted below 2500 deg F. Several methods of oxidation testing were used and compared. Stability of surface compounds was investigated metallographically. (For preceding period see SCNC-315.) (auth)
