Abstract

1,243,279. Tungsten base alloy; powder metallurgy; coating by spraying. METALLWERK PLANSEE A.G. & CO. K.G. Oct. 21, 1969 [Dec. 2, 1968], No.51456/69. Headings C7A, C7D and C7F. A target for X-ray tubes, consists, at least at the electron impact area, of an alloy comprising:- Pt 0À05-5% Ir 0-2% Os 0-5% and Re 0-10%, the balance being tungsten. The target may be made by powder metallurgy from powders which have been produced by simultaneous reduction. The example refers to forming a layer of the above composition as a powder on Mo powder in a die, compacting at 4 tons/cm<SP>2</SP> and then sintering in vacuo or in a neutral atmosphere at over 2000‹C. Spraying of the alloy on to a Mo or graphite substrate, preferably with a Re or Os interlayer in the latter case, is referred to.
