Abstract

1298293 Electrode materials METALLWERK PLANSEE AG & CO KG 11 May 1971 [2 June 1970] 14343/71 Heading H1D A rotary X-ray target consists of a Mo alloy body containing 50-500 p.p.m. B coated at least in the area of electron impact with W or W alloy. The Mo alloy body may include Hf, W, Ti and Zr; the W alloy coating may contain Re, Os and Ir. A target is made by filling a die with a powdered mass of Mo, MoB and HfB, adding a layer of powdered W containing 10% Re, compressing at 4 tons/cm.<SP>3</SP> sintering at 2000‹ C. in H 2 , forging and grinding.
