Method for making a high temperature, high pressure, erosion and corrosion resistant composite structure |
摘要 |
The present invention is a metallic composite which is resistant to erosion and corrosion at the high temperatures and pressures which are encountered in gun tubes, including projectile launchers. This composite comprises a ductile layer of rhenium or a rhenium alloy containing more than 20 percent rhenium, and a layer of a lower cost high strength material such as steel, nickel, nickel alloy, cobalt, or cobalt alloy. A solid solution of the two metals is formed between the two layers making a metallurgical bond. The metallurgical bond may be enhanced through the use of a bond promoter having solubility with both metallic layers.
