Abstract
A spray nozzle is provided having a body with a flow passage. At least along a portion of the flow passage the body has a depth-wise compositional variation having a cemented carbide first region and a cemented carbide second region closer to the flow passage than the first region, and having a higher boron content than a boron content, if any, of the first region. Also provided is a method of manufacturing such a spray nozzle whereby a boriding powder is placed into a passageway of a cemented carbide precursor of the spray nozzle and the precursor is heated so as to cause boron from the bonding powder to diffuse into the precursor.
