Abstract
A CFC tile 5 from the JET outer divertor, and CFC tiles from neutral beam shine-through and re-ionisation regions were coated with tungsten and exposed during the 2005-7 JET campaigns in preparation for the ITER-like wall project. Approximately 1.6 microns of coating were eroded from the tile 5 during high-delta discharges when the outer strike-point is on the tile. The coatings on the other tiles were unaffected by NB-heating and divertor discharges, however a tile mounted near the centre of the Inner Wall Guard Limiter lost all its coating from the surface within 10 mm of the tile leading edge; this probably occurred during the ramp-up phase of JET discharges.
