Cooling Hole Re-Opening

WAM has developed a highly innovative technique for salvaging blades and vanes that have cooling holes blocked or restricted by the coating process. The technique utilises multiple processes as required by the type of coating and the severity of the blockage or restriction. The yields from this recovery process are particularly high and offer a cost effective and rapid route to component salvage.
