摘要：

In the present study the influence of substrate material on the erosion resistance of three different TiN coated tool steels (two high speed steels and one cold work steel) has been investigated. The particle velocity was 20 m s(-1), two angles of impingement (20 degrees and 30 degrees) were used and silicon carbide was used as erodent. The results showed that, the carbide volume fraction and the impact toughness of the substrate material controlled the erosion rate of both coatings and substrates. It was concluded that as long as the test parameters allow the impinging particles to significantly affect the substrate material during erosive testing of a coated composite, the substrate material will influence the erosive response of the coating.
