Abstract: The present invention provides a blade tip for a rotary blade, the blade tip comprising a first portion and a radially-recessed second portion. A radially outermost surface of the first portion comprises a first abrasive coating e.g. a composite material comprising cubic boron nitride embedded in a matrix of nickel alloy. A radially outermost surface of the second portion comprises a second abrasive coating which has a greater resistance to oxidation than the first abrasive coating. The increased oxidation resistance of the second abrasive coating is achieved by providing a radially outer protective layer and/or using a material having a greater inherent oxidation resistance.

Abstract: The present invention provides an agitator for agitating a liquid (e.g. an electrolyte solution) containing particles (e.g. abrasive particles) within a tank. The agitator comprises an agitator body having an upper surface and a lower surface with at least one aperture extending through the agitator body. There is a one-way valve for allowing liquid flow through at least one aperture from the upper surface to the lower surface and for blocking liquid flow through at least one aperture from the lower surface to the upper surface.
