A gas turbine engine abradeable seal system is provided comprising a seal assembly and a cooperating interacting turbine blade. The turbine blade has a tip portion containing cubic boron nitride abrasive particles and the seal assembly has a superalloy substrate with a bond coat thereon having a surface roughness of at least 300 RA and a porous ceramic abradeable seal material on the bond coat having a porosity of from 5 to 15 volume %.

Abradeable seal system

A process is provided for producing an abrasive coating on a substrate surface by applying a bond coat by low pressure plasma spraying and anchoring to the bond coat abrasive particles by electroplating and embedding the particles into an oxidation resistant matrix by entrapment plating.

Method for producing abrasive tips for gas turbine blades

A method and apparatus is provided to coat the internal surfaces of a hollow article having gas flow passages by supplying a coating gas to the passages with the coating gas flow rate to at least two of the passages controlled to a different rate to deposit a coating of desired thickness on the internal surfaces of each passage.

An automated, self-contained apparatus for extracting meat from the appendages of crustaceans, such as crabs, the appendages having been severed from the body and cooked. The device includes a plurality of stations which recover and collect the meat in the appendages as well as dispose of the empty shell. The appendages are placed in radially extending recesses of a circular motor driven platter, the platter being used to transport the appendages from station to station. The appendages pass through a cutting station which removes the end of each appendage so that there is an opening large enough to allow the meat to be expelled and recovered when pressurized air is injected into the appendage at the third station, the meat extracting station. Pressurized air is also utilized at a second station to blow the appendage into its preferred position in its recess, and at the fourth station, the shell ejectment station, to remove the empty shells from the platter.
