Abstract: An improvement for a turbocompressor having a rotor, a stator and a casing, and an abradable coating provided between the rotor blades and the casing, or between the stator vanes and the rotor, such that the blades make initial contact with the coating to abrade the coating and produce a minimal clearance. The abradable coating is formed on a member having a first layer of carbon-fiber reinforced graphite adapted for attaching the coating member to the casing or rotor, and a second layer of graphite in the region in which the blade tips are intended to rub. The second layer may optionally contain, preferably radially oriented brush-type graphite-fiber reinforcements, or be entirely composed thereof.

Abstract: A rotor for axial-flow turbomachines with a locking pin connection for the blade roots. The blade roots are suspended in fiber-reinforced retaining rings and evidence cylindrical circumferential surfaces at their lower side. These cylindrical surfaces contact a correspondingly conformed circumferential surface on the metallic rotor disc.

Abstract: For the encapsulation of a molded ceramic member for high-temperature isostatic pressing, the molded member, which preferably is of silicon ceramic, is covered with a dense surface coating of an Si melt. Thereafter, the coating is exposed to an N.sub.2 atmosphere at a temperature of within about 800.degree. to 1400.degree. C. for so long until the Si coating is converted into a Si.sub.3 N.sub.4 coating.

Abstract: A shaped metal base component is formed, such as by casting or forging. The component is then thinly coated with a material, such as a ceramic material, having a higher melting point than the material of the shaped component. The coated component is then heated under zero gravity conditions up to a temperature which is below the melting point of the coating, but which is high enough to soften the component, the coating maintaining the shape of the component during the heating step. After completion of the heating step, the coated component is cooled under zero gravity conditions. The forming and coating of the component take place on earth, and the steps of heating and cooling the coated component are performed in space. After cooling the coated component, the coating is either stripped off the component or left on the component to form an integral part of the shaped body.
