This paper addresses an experimental investigation on the feasibility of using abrasive water jet (AWJ) for the drilling of small-diameter holes in aeroengines components. These components are sprayed with ceramic thermal barrier coating (TBC). The required holes are typically 0.5 to 1 mm in diameter with a drilling angle of 30 to 90 deg. The parameters of the AWJ were varied to study their effects on both quantitative and qualitative hole drilling parameters.
