“…In contrast, for the Ti-Si-C-N coated samples, SN1, SN2, and SN4, the erosion rate is lower at the low incident angle of 30°. These trends are consistent with the theoretical predictions and experimental observations that the erosion rate of ductile materials peaks at about 15-30°, while the erosion rate of brittle materials peaks at 90° [77][78][79][80][81]. As for the best coatings (SN5, SN6 and SN7), the trend is reversed and the erosion rate at 90°is basically zero.…”

Because of the serious consequences of turbomachinery erosion on their performance and life, it is important to have reliable methods for predicting their erosion when solid particles are ingested with the incoming flow. This is a very challenging problem since turbomachinery erosion is affected by many factors such as blade passage geometry, blade row location, rotational speed flow conditions, blade material and particles’ characteristics. Several studies which are essential to predicting blade surface erosion intensity and pattern, have been conducted at the University of Cincinnati’s Propulsion Laboratory over the past twenty-five years. This paper describes only some of the work done on erosion testing at high temperatures and velocities for different materials and coatings. The testing has been performed with a special high temperature erosion wind tunnel which simulates the aerodynamic conditions on the blades. The coated substrates reveal one order of magnitude less wear compared to some commercial non-CVD coatings on the same alloys. This study demonstrates that some coatings provide an excellent erosion resistance to INCO 718, LNCO 738, MAR-246, X-40 and Tungsten Carbide.

“…In particular, the group of Tabakoff have evaluated many different coatings found in aerospace applications (Pt-Al, Rd-Pt-Al, CrC, NiCrC, Cr, WC-Co, TiC, TiN, Al 2 O 3 and CVD diamond) in a specially constructed high temperature erosion test rig that simulates, as closely as possible, the particle impact conditions found in the engine [5,121,128,[138][139][140][141][142][143][144][145][146][147][148][149][150][151]. Although most of their studies were comparative, they have shown that in many cases the increased ductility at high temperature is beneficial for erosion resistance of hard coatings.…”
