Abstract:

Metallic and ceramic refractory coatings are being considered to extend the useful life of titanium under conditions of high temperatures and erosive atmospheres. The effects of the refractory composite system of flame-sprayed nickel-chrome, aluminum oxide, and copper, on the thermal characteristics of a titanium tube were investigated. The refractory composite system was examined metallographically for adhesion of coating to coating, and coating to substrate, porosity of coatings, and effect of deposition on the structure of the titanium substrate. A comparison of the weights of the composite titanium tube system and a similar size steel tube was made. A weight reduction of 19 percent is effected by the use of the coated titanium system. The advantages and disadvantages of each coating are discussed, and suggestions for future work are presented.
